4 A <strong>STEM</strong> APPROACH iii


Introduction<br />

What is <strong>STEM</strong>?<br />

In a nutshell, <strong>STEM</strong> is the integration of science,<br />

technologies, engineering and mathematics<br />

concepts using project-based and cooperative<br />

learning. Educators have been integrating learning<br />

areas since the beginning of time, so although the<br />

idea behind <strong>STEM</strong> is not new, this series hopes<br />

to make it easier for you to execute learning<br />

integration in the classroom.<br />

The Australian Government, and governments around the world, have placed a high priority on<br />

<strong>STEM</strong> skills. The future workforce will require current students to be creative and critical thinkers who<br />

can collaborate and design solutions to problems. The skills utilised in <strong>STEM</strong> have never been more<br />

valued.<br />

<strong>STEM</strong> education aims to prepare students for the roles of the future with skills such as innovation,<br />

creativity, reasoning, problem-solving, and technical science skills such as questioning, observing,<br />

systematic experimentation, and analysis and interpretation of data.<br />

Format of this book<br />

This series focuses on delivering a comprehensive and contemporary science program, culminating in<br />

a <strong>STEM</strong> project which applies the scientific knowledge acquired during the science lessons. The series<br />

incorporates the use of online <strong>res</strong>ources, digital devices and iPad® applications where appropriate, in<br />

order to enhance the use of technology in the classroom.<br />

The units<br />

The science units are organised by sub-strand—Biological sciences, Chemical sciences, Earth and<br />

space sciences and Physical sciences. At the start of each sub-strand unit, keywords, a unit overview<br />

and curriculum scope and sequence are provided, as shown be<strong>low</strong>.<br />

Each unit contains a term’s worth of work with 5–7 lessons, a summative assessment of the science<br />

knowledge with teacher notes, and a <strong>STEM</strong> project.<br />

THE CYCLE OF LIFE<br />

Living things have life cycles (ACSSU072)<br />

Living things depend on each other and the environment to survive (ACSSU073)<br />

Lesson 1<br />

Students use their prior knowledge to explore what<br />

What is an ecosystem? What<br />

an ecosystem is through focusing on the Daintree<br />

is the Daintree Rainfo<strong>res</strong>t<br />

Rainfo<strong>res</strong>t. Students answer questions about what kinds<br />

ecosystem?<br />

of living things exist there, why they exist there and how<br />

they might interact with each other, using an application<br />

like Popplet.<br />

Lesson 2<br />

Students explore the relationships between living<br />

What role does the cassowary<br />

things, focusing on the mutual relationship between<br />

play in the Daintree Rainfo<strong>res</strong>t?<br />

the cassowary and plants in the Daintree Rainfo<strong>res</strong>t and<br />

What is a mutually-beneficial<br />

conducting <strong>res</strong>earch using QR codes. Students p<strong>res</strong>ent<br />

relationship?<br />

their <strong>res</strong>earch using PowToon.<br />

Lesson 3<br />

Students <strong>res</strong>earch to find definitions for producer,<br />

What is a producer, consumer<br />

consumer and decomposer. Students practise sorting<br />

and decomposer and why are<br />

living things into these categories using a pyramid and<br />

they important to each other?<br />

an online game, and also sort living things from the<br />

Daintree Rainfo<strong>res</strong>t.<br />

Lesson 4<br />

Students act as biologists and <strong>res</strong>earch the life cycle of<br />

What is the life cycle of a<br />

a cassowary and one other animal from the Daintree<br />

cassowary?<br />

Rainfo<strong>res</strong>t. They then compare the life cycles using a<br />

Venn diagram.<br />

Lesson 5<br />

Students <strong>res</strong>earch the life cycle of a cassowary plum<br />

What is the life cycle of the<br />

using the internet. Students p<strong>res</strong>ent their life cycle by<br />

cassowary plum tree? How<br />

either drawing it or using a digital application. Students<br />

does the life cycle of a fruiting<br />

then discuss questions about the similarities and<br />

tree compare to that of an<br />

differences between plant and animal life cycles.<br />

animal?<br />

Lesson 6<br />

Students conduct online <strong>res</strong>earch to find out how<br />

How does human activity<br />

human activity impacts the Daintree ecosystem and<br />

impact an ecosystem like the<br />

p<strong>res</strong>ent their findings using a digital application.<br />

Daintree Rainfo<strong>res</strong>t?<br />

Summative assessment Students complete a written assessment covering what<br />

a mutually beneficial relationship is; offering examples<br />

of producers, consumers and decomposers; drawing<br />

life cycle diagrams of a cassowary and a fruiting plant;<br />

and describing human activities that have an impact on<br />

the Daintree Rainfo<strong>res</strong>t.<br />

<strong>STEM</strong> Project<br />

Students work in pairs to design and create a simple<br />

A web page for the Daintree<br />

web page to raise awareness about the endangered<br />

Daintree Rainfo<strong>res</strong>t ecosystem. The web page will<br />

include a survey to obtain information about which way<br />

people are willing to offer assistance to this cause.<br />

Background information<br />

• A habitat is a place where a living thing lives.<br />

• An ecosystem may consist of many habitats, and<br />

includes the interaction of living things. See for more information.<br />

• A set of ecosystems that have similar characteristics<br />

can be grouped into biomes such as wetland, desert,<br />

tundra, grassland, fo<strong>res</strong>t, rainfo<strong>res</strong>t and marine. At this<br />

stage students can refer to them as ecosystems rather<br />

than biomes.<br />

• The Daintree Rainfo<strong>res</strong>t is located on the north-east<br />

coast of Australia. It is a tropical rainfo<strong>res</strong>t which<br />

has existed for over 100 million years. It is unique<br />

because it reaches right to the coastline of the sea. The<br />

ecosystem is very complex and contains many diverse<br />

plant species and native animals such as the cassowary,<br />

and many other bird species, insects and amphibians<br />

such as the Northern barred frog.<br />

Answers<br />

Pages 29–30<br />

1. (a) A mutually-beneficial relationship (or mutualism) is one where both organisms benefit from the<br />

activities of the other.<br />

(b) Some examples include: a sea anemone and c<strong>low</strong>n fish, as c<strong>low</strong>n fish live in the tentacles<br />

of sea anemone for protection, while the c<strong>low</strong>n fish eat algae and clean the anemone; the<br />

cassowary and the cassowary plum, where the cassowary eats the fruit whole and disperses the<br />

seeds through excretion; termites and flagalettes, where the flagellates help digest the wood<br />

that the termite eats and get fed themselves; humans and animals breathe out carbon dioxide,<br />

while plants absorb the carbon dioxide and produce oxygen for humans to breathe; bees<br />

and f<strong>low</strong>ers, where the bees are attracted to the nectar of the f<strong>low</strong>ers and carry the pollen to<br />

other f<strong>low</strong>ers causing pollination; bull-horn acacia and ants, where the ants nest in the plant for<br />

protection, while protecting the plant from attack by other herbivo<strong>res</strong>; spider crabs and algae,<br />

where the algae grows on the shell of the crab and this serves to camouflage the crab; the redbilled<br />

ox-pecker and the impala, where the ox-pecker eats the ticks on the impala’s coat which<br />

provides food for it, while it grooms the impala and removes harmful parasites; pistol shrimp<br />

and goby, where the shrimp makes a burrow for protection, while the goby acts as a lookout<br />

because the shrimp has poor eyesight.<br />

Lesson plan<br />

Lesson 1<br />

Introduction:<br />

1. Go to Google Earth and show students the Daintree Rainfo<strong>res</strong>t<br />

by typing it into the search function. Zoom into various spots of the rainfo<strong>res</strong>t such as the river or<br />

tree canopies. Revise what a habitat is by asking students to name a habitat they can see; e.g. tree,<br />

river. What habitats can you see? What living things call these habitats home? What lives in the river?<br />

What lives in the tree canopy? QP<br />

Note: This is to establish what the students think they know, including any misconceptions, so it is<br />

important to not correct them at this stage.<br />

Development:<br />

2. Zoom out of the rainfo<strong>res</strong>t and show its expansive coverage. Describe the rainfo<strong>res</strong>t as an<br />

ecosystem. What is an ecosystem? How is it different to a habitat? What living things would you find<br />

in a rainfo<strong>res</strong>t ecosystem like the Daintree? Why do certain plants and animals live there? QP<br />

3. Watch a video describing what an ecosystem is at . Write a class<br />

definition and display it on a word wall. Students may wish to check for a definition using an online<br />

dictionary. PC<br />

4. Display an image of the fo<strong>res</strong>t growth of the Daintree such as . Place<br />

a large piece of poster paper at four stations, each labelled with one of the questions from page 6.<br />

Divide the class into four groups, with one at each station. Students discuss and write one answer<br />

to the question in five minutes, before passing the paper to the next group in a clockwise motion.<br />

Students read the previous group’s answer, discuss and then write their own answer. No answers<br />

can be repeated. At the end of the activity there will be four answers to each question. Each group<br />

sha<strong>res</strong> their predicted answers for each question. Alternatively, an application such as Popplet may<br />

be used to record answers in a concept map; just place one iPad ® at each station, with the question<br />

typed in for students to add their answers. QP PA<br />

Differentiation<br />

• Less capable students can draw pictu<strong>res</strong> in <strong>res</strong>ponse and contribute to the discussion.<br />

• More capable students can write more detailed <strong>res</strong>ponses, or take the role of scribe.<br />

Reflection:<br />

5. What would you like to find out about the Daintree ecosystem? Students name one thing they want<br />

to find out. As a class, add the questions to an online concept map such as . Type ‘Daintree Rainfo<strong>res</strong>t’ as the starting ‘node’, add a ‘child node’ for the first question,<br />

then a ‘sibling node’ for each question added. Print out the file and display on a word wall. QP<br />

<strong>STEM</strong> project<br />

The <strong>STEM</strong> project provides students with the opportunity to apply what they have learned in the<br />

previous science lessons while incorporating technologies, engineering and mathematics concepts<br />

where possible. The project entails group collaboration and an extended learning period of<br />

3–4 weeks. This gives students a real-life experience of working with ‘colleagues’ to share ideas<br />

and test designed solutions. Each <strong>STEM</strong> project contains an overview listing <strong>STEM</strong> concepts and<br />

ecosystem.<br />

Concepts overview:<br />

<strong>Science</strong><br />

• Apply knowledge of the relationships that exist between living things that interact in the Daintree<br />

Rainfo<strong>res</strong>t environment.<br />

• Apply knowledge of life cycles of plants and animals from the Daintree Rainfo<strong>res</strong>t.<br />

• Conduct an investigation of environmental awareness campaigns and why the Daintree needs to<br />

be saved.<br />

• Communicate findings in the form of a web page.<br />

• Understand the impacts people may have on an ecosystem and how science helps explain this.<br />

Technology/Engineering<br />

• Produce drawings to show featu<strong>res</strong> of a web page design.<br />

• Evaluate design ideas, based on criteria.<br />

• Sequence steps to produce a web page.<br />

• Use a digital photography device to upload images to a computer.<br />

• Recognise that text and images are forms of data when stored using a digital system.<br />

• Collect information from online sources, and p<strong>res</strong>ent and organise information in a web page.<br />

• Explore and incorporate common navigation elements on a web page.<br />

• Use a web page and online survey to collect data to help meet a community need.<br />

• Manage a project to publish a web page safely with appropriate privacy settings.<br />

Mathematics<br />

• Use survey questions to collect data about the level of awareness of the Daintree Rainfo<strong>res</strong>t.<br />

Alternative project ideas:<br />

• Students grow a tomato plant over the course of a term and track its development using a<br />

camera or video recording, in order to compile a documentary. The documentary can then be<br />

shared by emailing to friends and family.<br />

• Students make a stop-motion video based on When the fo<strong>res</strong>t meets the sea by Jeannie Baker, to<br />

raise awareness of the human impact on the ecosystem of the Daintree Rainfo<strong>res</strong>t. An example<br />

can be seen at . Students share the link to their video or upload it<br />

to a class blog or website.<br />

• Students explore the activity at Scootle Education , which al<strong>low</strong>s<br />

them to design an enclosure for an injured cassowary. Students then apply their knowledge of<br />

the cassowary’s life cycle and mutually-beneficial relationships with plants, to construct a 3D<br />

model of a sanctuary for injured or sick cassowaries.<br />

THE CYCLE OF LIFE<br />

Teacher notes<br />

<strong>STEM</strong> project:<br />

Create a web page to help raise awareness about the endangered Daintree Rainfo<strong>res</strong>t<br />

ecosystem.<br />

Estimated duration: 3-4 weeks<br />

Notes: Prior to commencing it is advised to send<br />

a note to parents such as the one provided on<br />

page 38, requesting permission for their child to<br />

create a website, if permission has not yet been<br />

given as part of a whole school policy already.<br />

If some parents do not al<strong>low</strong> permission then<br />

students can simply create a design and layout<br />

of a web page using paper and markers.<br />

Teachers will also need to set up a teacher<br />

website account at and add a class and student names.<br />

Students can then be provided with individual<br />

login details to enter into in order to create their web page.<br />

Be sure to set the class settings to private.<br />

1. Introduce the project<br />

• Display page 34 and read through the<br />

problem, ensuring students understand<br />

what the challenge is.<br />

• Display a website that is about saving the<br />

Daintree Rainfo<strong>res</strong>t, such as , in order to illustrate what<br />

current web pages have done to help raise<br />

awareness.<br />

2. Investigate<br />

• Students <strong>res</strong>earch and explore existing web<br />

pages to decide what featu<strong>res</strong> they like,<br />

using the links on page 36.<br />

• Students should also revisit their previous<br />

science work to ensure they understand<br />

what life cycles are affected in the Daintree<br />

and how, as well as how the relationships<br />

between the living things are affected.<br />

• Students should also spend some time<br />

familiarising themselves with weebly and<br />

the components of a web page, by logging<br />

in and exploring.<br />

Teacher notes<br />

<strong>STEM</strong> project<br />

3. Design, plan and manage<br />

• Students plan and search for impactful<br />

images/photographs to use on their web<br />

page.<br />

• Students write a catchy title for the web<br />

page and plan the content for the text,<br />

including the keywords. Students also write<br />

three appropriate survey questions to find<br />

out how people are willing to help save the<br />

Daintree. Students should be able to come<br />

up with questions such as ‘Would you be<br />

willing to take part in a tree planting day?’,<br />

‘Would you be willing to donate money?’,<br />

‘Would you be willing to hold a fundraiser<br />

activity?’, ‘Would you be willing to sponsor<br />

a cassowary?’.<br />

• Using an A3 piece of paper students plan<br />

the layout of their web page, placing the<br />

location of the headline, text, images and<br />

survey.<br />

4. Create<br />

• Students create their web page based on<br />

their design. Explain that the web page is<br />

set to private, and discuss the meaning of<br />

and the reasons for this.<br />

• Students will need to upload images and<br />

enter text and survey questions. Note: The<br />

answers to the survey questions will be sent<br />

to the email add<strong>res</strong>s linked to the account.<br />

5. Evaluate and refine<br />

• Students check that their web page does<br />

not contain any errors, and that it contains<br />

sufficient text including the keywords, as<br />

well as appropriate images to make it eyecatching.<br />

6. Communicate<br />

• Students publish their website and share<br />

the URL with friends and family, along<br />

with any passwords required to access the<br />

private web page.<br />

A WEB PAGE FOR THE DAINTREE<br />

The problem<br />

In the 1970s developers wanted to tear down the Daintree Rainfo<strong>res</strong>t.<br />

Protestors joined together and stopped them, but the threat from all kinds of<br />

human activity still remains. This has a devastating effect on the animals and<br />

plants that depend on each other to survive in the Daintree.<br />

How can you help raise awareness to protect this important ecosystem?<br />

The task<br />

You need to design and create a simple web page to explain which living<br />

things exist in the Daintree, how they are in danger and why they need<br />

protection.<br />

Things to consider<br />

• You must work in pairs.<br />

• The web page must have a catchy title<br />

www.thekidzsite.com<br />

and be easy to navigate.<br />

NEWS<br />

• The web page must have an engaging<br />

description of the living things that are<br />

in danger and how their life cycles and<br />

relationships are affected by human<br />

activity.<br />

• You must include the keywords<br />

producer, consumer, decomposer,<br />

mutually-beneficial, ecosystem and life<br />

cycle in your text.<br />

• The web page must contain at least one image or photograph.<br />

• You will need to include a survey on your page to collect data about how<br />

people would be willing to help protect the Daintree.<br />

• You will need to write three survey questions.<br />

Parent letter<br />

During this term the class has been learning about the life cycle of the<br />

cassowary and plants in the Daintree Rainfo<strong>res</strong>t. We have also been learning<br />

about the relationships that exist in ecosystems and how living things depend<br />

on each other for survival.<br />

As part of this, the students are going to raise awareness of the endangered<br />

Daintree Rainfo<strong>res</strong>t ecosystem, and the plants and animals within that<br />

ecosystem that are threatened due to human activity.<br />

The students have been assigned a project to create a simple web page<br />

containing information about this issue, which you will receive a link to once<br />

complete.<br />

For your child to be able to create a web page, I require your permission. The<br />

page will be secure and set to private, for which a password will be required.<br />

No images of the students will be used and the students will be monitored at<br />

all times. The web page is created under a teacher educational account, which<br />

can only be accessed by the assigned students. See for more information.<br />

<strong>STEM</strong> project<br />

A web page for the Daintree<br />

Students use their prior knowledge to explore what<br />

an ecosystem is through focusing on the Daintree<br />

Rainfo<strong>res</strong>t. Students answer questions about what kinds<br />

of living things exist there, why they exist there and how<br />

they might interact with each other, using an application<br />

like Popplet.<br />

Students explore the relationships between living<br />

things, focusing on the mutual relationship between<br />

the cassowary and plants in the Daintree Rainfo<strong>res</strong>t and<br />

conducting <strong>res</strong>earch using QR codes. Students p<strong>res</strong>ent<br />

their <strong>res</strong>earch using PowToon.<br />

Students <strong>res</strong>earch to find definitions for producer,<br />

consumer and decomposer. Students practise sorting<br />

living things into these categories using a pyramid and<br />

an online game, and also sort living things from the<br />

Daintree Rainfo<strong>res</strong>t.<br />

Students act as biologists and <strong>res</strong>earch the life cycle of<br />

a cassowary and one other animal from the Daintree<br />

Rainfo<strong>res</strong>t. They then compare the life cycles using a<br />

Venn diagram.<br />

Students <strong>res</strong>earch the life cycle of a cassowary plum<br />

using the internet. Students p<strong>res</strong>ent their life cycle by<br />

either drawing it or using a digital application. They<br />

then discuss questions about the similarities and<br />

differences between plant and animal life cycles.<br />

Students conduct online <strong>res</strong>earch to find out how<br />

human activity impacts the Daintree ecosystem and<br />

p<strong>res</strong>ent their findings using a digital application.<br />

Students complete a written assessment covering what<br />

a mutually beneficial relationship is; offering examples<br />

of producers, consumers and decomposers; drawing<br />

life cycle diagrams of a cassowary and a fruiting plant;<br />

and describing human activities that have an impact on<br />

the Daintree Rainfo<strong>res</strong>t.<br />

Students work in pairs to design and create a simple<br />

web page to raise awareness about the endangered<br />

Daintree Rainfo<strong>res</strong>t ecosystem. The web page will<br />

include a survey to obtain information about which way<br />

people are willing to offer assistance to this cause.<br />

Background information<br />

• A habitat is a place where a living thing lives.<br />

• An ecosystem may consist of many habitats, and<br />

includes the interaction of living things. See for more information.<br />

• A set of ecosystems that have similar characteristics<br />

can be grouped into biomes such as wetland, desert,<br />

tundra, grassland, fo<strong>res</strong>t, rainfo<strong>res</strong>t and marine. At this<br />

stage students can refer to them as ecosystems rather<br />

than biomes.<br />

• The Daintree Rainfo<strong>res</strong>t is located on the north-east<br />

coast of Australia. It is a tropical rainfo<strong>res</strong>t which<br />

has existed for over 100 million years. It is unique<br />

because it reaches right to the coastline of the sea. The<br />

ecosystem is very complex and contains many diverse<br />

plant species and native animals such as the cassowary,<br />

and many other bird species, insects and amphibians<br />

such as the Northern barred frog.<br />

Assessment focus:<br />

• Use the four posters as a diagnostic<br />

assessment to gauge the level<br />

of understanding regarding the<br />

four questions posed about the<br />

Daintree ecosystem.<br />

THE CYCLE OF LIFE<br />

Lesson 1<br />

Lesson plan<br />

Introduction:<br />

1. Go to Google Earth and show students the Daintree Rainfo<strong>res</strong>t<br />

by typing it into the search function. Zoom into various spots of the rainfo<strong>res</strong>t such as the river or<br />

tree canopies. Revise what a habitat is. What habitats can you see? What living things call these<br />

habitats home? What lives in the river? What lives in the tree canopy? QP<br />

Note: This is to establish what the students think they know, including any misconceptions, so it is<br />

important to not correct them at this stage.<br />

Development:<br />

2. Zoom out of the rainfo<strong>res</strong>t and show its expansive coverage. Describe the rainfo<strong>res</strong>t as an<br />

ecosystem. What is an ecosystem? How is it different to a habitat? What living things would you find<br />

in a rainfo<strong>res</strong>t ecosystem like the Daintree? Why do certain plants and animals live there? QP<br />

3. Watch a video describing what an ecosystem is at . Write a class<br />

definition and display it on a word wall. Students may wish to check for a definition using an online<br />

dictionary. PC<br />

<strong>Science</strong> inquiry focus:<br />

What role does the cassowary play in the Daintree Rainfo<strong>res</strong>t?<br />

What is a mutually-beneficial relationship?<br />

• Questioning and predicting QP<br />

• Planning and conducting PC<br />

• Processing and analysing data and information PA<br />

• Communicating C<br />

<strong>Science</strong> as a Human Endeavour:<br />

• Students make predictions about the important role of the<br />

cassowary to the Daintree ecosystem.<br />

• Students describe the relationship between the existence<br />

of the cassowary and the existence of plants in the Daintree<br />

ecosystem.<br />

Technology/Engineering/Mathematics links:<br />

• using an internet search engine to find information<br />

• using a QR code reader to find information<br />

• writing a plan for the summary of key facts to be p<strong>res</strong>ented<br />

• p<strong>res</strong>enting information using a digital tool such as PowToon<br />

or PowerPoint ®<br />

Background information<br />

• A cassowary is a large, flightless bird found in Papua New<br />

Guinea, while the Southern cassowary is found in the<br />

Daintree Rainfo<strong>res</strong>t in Queensland.<br />

• The cassowary is an important part of the Daintree<br />

Rainfo<strong>res</strong>t ecosystem and is considered a keystone<br />

species.<br />

• A keystone species is one which has a large effect on the<br />

ecosystem it is found in. It has a vital role in maintaining<br />

the function of the ecosystem and without that species,<br />

the ecosystem may cease to exist. The cassowary is vital<br />

in terms of its propagation of the plant species within<br />

the Daintree. Without the cassowary many plant species<br />

would die out. The cassowary consumes seeds and fruits<br />

whole and disperses the seeds through its excretions as it<br />

moves through the rainfo<strong>res</strong>t. Some of these seeds might<br />

not otherwise be able to reach these varied locations. The<br />

cassowary has been called the ‘rainfo<strong>res</strong>t gardener’.<br />

• The relationship between the fruit plants and the<br />

cassowary is considered to be mutually beneficial. They<br />

depend on each other for survival; the cassowary spreads<br />

the fruit seeds, after it eats the fruit whole.<br />

THE CYCLE OF LIFE<br />

Lesson plan<br />

Introduction:<br />

1. Introduce the cassowary by playing a guessing game with students. Give them clues about this<br />

animal by saying the fol<strong>low</strong>ing. QP<br />

• I am a flightless bird that lives in the Daintree Rainfo<strong>res</strong>t.<br />

• I am the third-largest bird in the world and can grow up to 1.8 m tall.<br />

• I am descended from a dinosaur.<br />

• I am a frugivore which means I mostly eat fruit.<br />

• I am the most dangerous bird in the world.<br />

• My name means ‘horned head’.<br />

• I am considered the guardian of the rainfo<strong>res</strong>t.<br />

Identify the animal as a cassowary and show images from .<br />

Development:<br />

2. In pairs, students discuss the fol<strong>low</strong>ing questions: Why do you think the cassowary is considered the<br />

guardian of the rainfo<strong>res</strong>t? What does this role mean? Do all living things have a role to play in their<br />

ecosystem? QP<br />

3. Look at the list of animals exclusive to the Daintree at and the<br />

documentary about the cassowary from BBC Earth at .<br />

4. In small groups, students discuss the relationships between living things as shown in the Daintree<br />

video. Focus on the cassowary. What does the cassowary eat? Why is it important to the Daintree<br />

ecosystem? How does it help plants? C<br />

5. Students use the template on page 9 to plan and <strong>res</strong>earch information about the role of the<br />

cassowary. They may wish to replay the documentary using the QR code or URL link at the top of<br />

page 9 and conduct further <strong>res</strong>earch. PC<br />

6. Students compile the information into five facts and create a PowToon using a computer (see Resources). The file should be saved, using their name/group name, for<br />

later access. PA C<br />

Differentiation<br />

• Less capable students can write using more simple phrases, or use an alternative application like<br />

Chatterbox which uses audio recordings instead.<br />

• More capable students can write more detailed information or conduct further <strong>res</strong>earch to<br />

supplement their five facts.<br />

Teacher notes<br />

<strong>Science</strong> inquiry focus:<br />

What is a producer, consumer and decomposer and why<br />

are they important to each other?<br />

<strong>Science</strong> Inquiry Skills:<br />

• Questioning and predicting QP<br />

• Planning and conducting PC<br />

• Processing and analysing data and information PA<br />

• Communicating C<br />

<strong>Science</strong> as a Human Endeavour:<br />

• Students describe the relationship between living things<br />

in an ecosystem.<br />

• Students discover that humans are living things that may<br />

have an impact on the delicate balance of relationships<br />

in an ecosystem.<br />

Technology/Engineering/Mathematics links:<br />

• using QR code readers and technology to conduct<br />

<strong>res</strong>earch<br />

• viewing and sorting data from an online game<br />

Background information<br />

• Decomposers are considered nature’s recyclers; they<br />

process dead materials and turn them into nutrients.<br />

For example, earthworms take in dead leaves and soil,<br />

and churn out nutrient-rich waste which promotes<br />

soil health, which in turn supports plant growth.<br />

Decomposers enable producers to live.<br />

• Producers are living things that make their own<br />

food. This includes plants, f<strong>low</strong>ers, trees, fruits and<br />

vegetables. They produce their own food using<br />

sunlight and the process of photosynthesis. Consumers<br />

that eat producers are called herbivo<strong>res</strong>.<br />

• Consumers are living things that eat plants or animals<br />

to obtain energy and nutrients. Consumers can be<br />

herbivo<strong>res</strong>, carnivo<strong>res</strong> or omnivo<strong>res</strong>.<br />

• Decomposers, producers and consumers have an<br />

interdependent relationship. If one dies out, then the<br />

whole ecosystem is thrown out of balance and can<br />

disappear. If there are competing consumers, then the<br />

less able consumer is also at risk of dying out.<br />

Assessment focus:<br />

• Observe students’ verbal <strong>res</strong>ponses<br />

to Step 7 as a formative assessment<br />

of the understanding of the<br />

relationship between producers,<br />

consumers and decomposers.<br />

Lesson plan<br />

Introduction:<br />

1. Display a digital copy of page 12 on the whiteboard. What is this person eating for lunch? What<br />

does the cow eat? How does the corn get food? What job does the worm do? There is a f<strong>low</strong> of<br />

energy in every ecosystem. Where things get their energy from depends on whether they are a<br />

producer, consumer or decomposer. QP<br />

2. Write the terms ‘producer’, ‘consumer’ and ‘decomposer’ on the board. In small groups, students<br />

discuss what they think these terms mean. Can you guess what the cow is, or what the corn is, or the<br />

human or the worm? QP<br />

Development:<br />

3. As a class, watch the video Decomposers at . C<br />

4. Individually, students go to or scan the QR code on page 13 to<br />

<strong>res</strong>earch and write a definition for producer, consumer and decomposer. Students can also confirm<br />

which living things from the image shown in Step 1 are consumers, producers, decomposers, as<br />

well as list other examples on the <strong>res</strong>ource sheet. PC PA C<br />

5. Individually, or in pairs as digital equipment al<strong>low</strong>s, students practise sorting producers, consumers<br />

and decomposers by playing the game at . Note: The URL is written<br />

at the bottom of page 13. Alternatively, play the game as a class on the whiteboard. PA<br />

Differentiation<br />

• Less capable students who require more practice identifying producers, consumers and<br />

decomposers can use page 14 to conduct a card sort.<br />

• More capable students can conduct further <strong>res</strong>earch and write more extensive answers for<br />

page 13.<br />

6. As a class, discuss the importance of the components of an ecosystem in terms of producers,<br />

consumers and decomposers. What would happen if one of these producers, consumers or<br />

decomposers died out from the ecosystem? Refer back to the Daintree Rainfo<strong>res</strong>t by looking at the<br />

living things on page 15 or searching for these images online. In pairs, students construct a table<br />

and list the living things that are producers, consumers and decomposers based on the definitions<br />

and previous <strong>res</strong>earch. QP PA<br />

Reflection:<br />

7. Select students at random to name a producer, consumer or decomposer. Individually, students<br />

complete the sentence If all decomposers died out in an ecosystem then … on the back of page 13<br />

Background information<br />

• The life cycle of a cassowary can be viewed at<br />

, along with other<br />

information about its characteristics, height,<br />

population, diet and habitat.<br />

• There are four stages in a cassowary life cycle: the<br />

cassowary appears different at each stage and<br />

changes its colouring as it grows.<br />

• The female lays around four eggs, which the male<br />

sits on for two months. The chick is then raised by<br />

the male for up to 18 months, until it is old enough<br />

to fend for itself.<br />

3. Display a digital copy of the concept cartoon on page 18. What do you think might be different<br />

about the way babies of cassowaries are raised, by looking at this cartoon? Students form groups to<br />

discuss, and report back their best answer. QP<br />

4. Individually or in pairs, students use a computer to <strong>res</strong>earch and construct a report about the<br />

cassowary life cycle, adding as much detail about each stage as possible. This is based on<br />

the website . The report must contain diagrams, labels and a<br />

description based on the <strong>res</strong>earch. Students can use page 19 to take notes and then p<strong>res</strong>ent their<br />

• The cassowary plum is the favourite food of the cassowary<br />

in the Daintree Rainfo<strong>res</strong>t. The animal plays a role in<br />

dispersing the seed of the cassowary plum around<br />

the floor of the rainfo<strong>res</strong>t by excreting the seed. More<br />

information about the diet of the cassowary can be found<br />

at .<br />

• The life cycle of a plant is similar to that of an animal in<br />

that it grows bigger, looks different from the beginning<br />

to the end, they both reproduce and they both die. The<br />

main difference is that plants often rely on animals for<br />

pollination and/or seed dispersal. Plants have seeds to<br />

reproduce, but animals have eggs. There are obvious<br />

physical characteristics that are different between plants<br />

and animals as they go through their life cycle.<br />

Assessment focus:<br />

• Use pages 23 and 24 as a<br />

formative assessment of the<br />

student’s understanding of the<br />

life cycle of a fruiting plant and<br />

how it compa<strong>res</strong> to that of an<br />

animal.<br />

THE CYCLE OF LIFE<br />

Lesson plan<br />

Introduction:<br />

1. Place some different seeds into sandwich bags and pass them around for students to observe.<br />

What are these? What will they become? What is the process? What will it look like? On a<br />

whiteboard, draw students’ predictions about the life cycle of a plant. QP<br />

Development:<br />

2. Show the image of a cassowary plum, as an example of the favourite food of the cassowary, at<br />

. How does this fruit grow? What do you think a cassowary plum’s life<br />

cycle looks like? QP<br />

3. Display the diagram of the life cycle of a tomato plant at . Discuss<br />

the different stages, highlighting what happens with the seeds to begin the life cycle and how<br />

f<strong>low</strong>ers eventually grow and are pollinated by bees. How are the seeds spread? What is pollination?<br />

What might be different or the same about the cassowary plum’s life cycle? QP PC<br />

4. Watch the video about fruiting plants and the role of fruit in the life cycle, at . Stop it at 4:05. What role does a cassowary play in the seed dispersal of the plum tree?<br />

PC QP<br />

5. Students draw a life cycle of the cassowary plum tree using page 23 if required. Additional images<br />

of what a cassowary plum looks like at different stages can be viewed at . Students should include details about how the seeds are dispersed by the cassowary<br />

bird. They can then compare the life cycle with their prediction from Step 1. Alternatively, students<br />

may wish to p<strong>res</strong>ent their life cycle using a digital application of their choice. PC PA C<br />

Differentiation<br />

• Less capable students can use the life cycle diagram outline on page 23 to assist them.<br />

• More capable students can draw their own life cycle diagram and label it with more detail.<br />

6. In small groups, students compare the life cycle of animals from the previous lesson, to the life<br />

cycle of plants. Display page 24 to guide group discussions. PA C<br />

Reflection:<br />

7. Groups share what they learnt about the life cycle of a fruiting plant and offer one suggestion about<br />

how it is similar and different to that of an animal. Discuss the impact that the cassowary has on<br />

the cassowary plum life cycle. What would happen to the plum tree if cassowaries became extinct?<br />

• Human impact on environments like the Daintree<br />

Rainfo<strong>res</strong>t include activities such as logging, mining,<br />

development and tourism. Logging is when fo<strong>res</strong>t trees<br />

are cut down to sell for timber. Mining could become a<br />

problem to the Daintree considering there are several tin<br />

mine leases in the area. Development is when there are<br />

commercial inte<strong>res</strong>ts in the area leading to clearing land to<br />

make way for housing, roads and fences. Tourism impacts<br />

the area due to the number of buses and cars that drive<br />

through the rainfo<strong>res</strong>t, bringing pollution and destroying<br />

living things to make way for driving paths.<br />

activities of the other.<br />

(b) Some examples include: a sea anemone and c<strong>low</strong>n fish, as c<strong>low</strong>n fish live in the tentacles<br />

of sea anemone for protection, while the c<strong>low</strong>n fish eat algae and clean the anemone; the<br />

cassowary and the cassowary plum, where the cassowary eats the fruit whole and disperses the<br />

seeds through excretion; termites and flagalettes, where the flagellates help digest the wood<br />

that the termite eats and get fed themselves; humans and animals breathe out carbon dioxide,<br />

while plants absorb the carbon dioxide and produce oxygen for humans to breathe; bees<br />

and f<strong>low</strong>ers, where the bees are attracted to the nectar of the f<strong>low</strong>ers and carry the pollen to<br />

other f<strong>low</strong>ers causing pollination; bull-horn acacia and ants, where the ants nest in the plant for<br />

protection, while protecting the plant from attack by other herbivo<strong>res</strong>; spider crabs and algae,<br />

where the algae grows on the shell of the crab and this serves to camouflage the crab; the redbilled<br />

ox-pecker and the impala, where the ox-pecker eats the ticks on the impala’s coat which<br />

provides food for it, while it grooms the impala and removes harmful parasites; pistol shrimp<br />

and goby, where the shrimp makes a burrow for protection, while the goby acts as a lookout<br />

because the shrimp has poor eyesight.<br />

<strong>STEM</strong> project:<br />

Teacher notes<br />

Create a web page to help raise awareness about the endangered Daintree Rainfo<strong>res</strong>t<br />

ecosystem.<br />

Estimated duration: 3-4 weeks<br />

Notes: Prior to commencing it is advised to send<br />

a note to parents such as the one provided on<br />

page 38, requesting permission for their child to<br />

create a website, if permission has not yet been<br />

given as part of a whole school policy already.<br />

If some parents do not al<strong>low</strong> permission then<br />

students can simply create a design and layout<br />

of a web page using paper and markers.<br />

Teachers will also need to set up a teacher<br />

website account at and add a class and student names.<br />

Students can then be provided with individual<br />

login details to enter into in order to create their web page.<br />

Be sure to set the class settings to private.<br />

1. Introduce the project<br />

• Display page 34 and read through the<br />

problem, ensuring students understand<br />

what the challenge is.<br />

• Display a website that is about saving the<br />

Daintree Rainfo<strong>res</strong>t, such as , in order<br />

to illustrate what current web pages have<br />

done to help raise awareness.<br />

2. Investigate<br />

• Students <strong>res</strong>earch and explore existing web<br />

pages to decide what featu<strong>res</strong> they like,<br />

using the links on page 36.<br />

• Students should also revisit their previous<br />

science work to ensure they understand<br />

what life cycles are affected in the Daintree<br />

and how, as well as how the relationships<br />

between the living things are affected.<br />

• Students should also spend some time<br />

familiarising themselves with weebly and<br />

the components of a web page, by logging<br />

in and exploring.<br />

3. Design, plan and manage<br />

• Students plan and search for impactful<br />

images/photographs to use on their web<br />

page.<br />

• Students write a catchy title for the web<br />

page and plan the content for the text,<br />

including the keywords. Students also write<br />

three appropriate survey questions to find<br />

out how people are willing to help save the<br />

Daintree. Students should be able to come<br />

up with questions such as ‘Would you be<br />

willing to take part in a tree planting day?’,<br />

‘Would you be willing to donate money?’,<br />

‘Would you be willing to hold a fundraiser<br />

activity?’, ‘Would you be willing to sponsor<br />

a cassowary?’.<br />

• Using an A3 piece of paper students plan<br />

the layout of their web page, placing the<br />

location of the headline, text, images and<br />

survey.<br />

4. Create<br />

• Students create their web page based on<br />

their design. Explain that the web page is<br />

set to private, and discuss the meaning of<br />

and the reasons for this.<br />

• Students will need to upload images and<br />

enter text and survey questions. Note: The<br />

answers to the survey questions will be sent<br />

to the email add<strong>res</strong>s linked to the account.<br />

5. Evaluate and refine<br />

• Students check that their web page does<br />

not contain any errors, and that it contains<br />

sufficient text including the keywords, as<br />

well as appropriate images to make it eyecatching.<br />

6. Communicate<br />

• Students publish their website and share<br />

the URL with friends and family, along<br />

with any passwords required to access the<br />

private web page.<br />

The problem<br />

Project brief<br />

A WEB PAGE FOR THE DAINTREE<br />

In the 1970s developers wanted to tear down the Daintree Rainfo<strong>res</strong>t.<br />

Protestors joined together and stopped them, but the threat from all kinds of<br />

human activity still remains. This has a devastating effect on the animals and<br />

plants that depend on each other to survive in the Daintree.<br />

How can you help raise awareness to protect this important ecosystem?<br />

The task<br />

You need to design and create a simple web page to explain which living<br />

things exist in the Daintree, how they are in danger and why they need<br />

protection.<br />

Things to consider<br />

• You must work in pairs.<br />

• The web page must have a catchy title<br />

and be easy to navigate.<br />

• The web page must have an engaging<br />

description of the living things that are<br />

in danger and how their life cycles and<br />

relationships are affected by human<br />

activity.<br />

• You must include the keywords<br />

producer, consumer, decomposer,<br />

mutually beneficial, ecosystem and life<br />

cycle in your text.<br />

• The web page must contain at least one image or photograph.<br />

• You will need to include a survey on your page to collect data about how<br />

people would be willing to help protect the Daintree.<br />

• You will need to write three survey questions.<br />

THE CYCLE OF LIFE<br />

Dear<br />

During this term the class has been learning about the life cycle of the<br />

cassowary and plants in the Daintree Rainfo<strong>res</strong>t. We have also been learning<br />

about the relationships that exist in ecosystems and how living things depend<br />

on each other for survival.<br />

As part of this, the students are going to raise awareness of the endangered<br />

Daintree Rainfo<strong>res</strong>t ecosystem, and the plants and animals within that<br />

ecosystem that are threatened due to human activity.<br />

The students have been assigned a project to create a simple web page<br />

containing information about this issue, which you will receive a link to once<br />

complete.<br />

For your child to be able to create a web page, I require your permission. The<br />

page will be secure and set to private, for which a password will be required.<br />

No images of the students will be used and the students will be monitored at<br />

all times. The web page is created under a teacher educational account, which<br />

can only be accessed by the assigned students. See for more information.<br />

Natural and processed materials have a range of physical properties that can influence their<br />

use (ACSSU074)<br />

Pages<br />

Lesson 1<br />

What are natural and<br />

processed materials?<br />

Lesson 2<br />

What are the properties and<br />

uses of a natural material like<br />

wool?<br />

Lesson 3<br />

What are the properties and<br />

uses of a synthetic material<br />

like polyester? How does this<br />

compare to the properties and<br />

uses of a natural material like<br />

cotton?<br />

Lesson 4<br />

What are the properties<br />

and uses of other common<br />

materials?<br />

Students explore examples of natural and processed<br />

materials and take digital photographs of examples in<br />

the school grounds to classify.<br />

This focuses on wool—a natural material. Students<br />

discuss how wool and other natural materials are<br />

used, then conduct tests to confirm the properties of<br />

wool, including flexibility, elasticity, water <strong>res</strong>istance/<br />

absorption, keeping warm and keeping cool.<br />

Students explore a synthetic material like polyester and<br />

compare it to cotton through testing various properties<br />

such as elasticity, water <strong>res</strong>istance/absorption, static and<br />

strength. Students think of the properties in terms of<br />

what gym clothes should be made of and read a science<br />

article about a study in this area.<br />

Students explore materials used to create designed<br />

solutions such as metal, PVC, glass, cardboard, ceramic,<br />

rubber and concrete and note their properties. Students<br />

then match a material to a specific task based on the<br />

required properties and the purpose.<br />

Lesson 5<br />

This lesson explo<strong>res</strong> waste management and how<br />

rubbish ends up in landfill where it is left to biodegrade.<br />

What is biodegradable Students conduct an experiment to test which materials<br />

material and why is it important biodegrade in soil over a two-week period, and discuss<br />

to waste management? the implications of the biodegradability of materials.<br />

Lesson 6<br />

How does plastic contribute<br />

to ocean pollution? What<br />

properties make plastic<br />

harmful?<br />

Summative assessment<br />

<strong>STEM</strong> project<br />

Bioplastics<br />

The focus is on plastic, a synthetic material, which is<br />

used to create many products. Students investigate the<br />

properties of different plastic types and what makes<br />

them harmful to marine life and oceans. Students are<br />

introduced to the Great Pacific Garbage Patch and<br />

consider what can be done to manage plastic waste<br />

better, considering its inability to biodegrade.<br />

Students complete a written assessment that covers<br />

the concepts of natural and processed materials, their<br />

properties and their uses, and how this applies to waste<br />

management.<br />

Students create a bioplastic as an alternative to<br />

synthetic plastic, and design and create a product<br />

with the bioplastic material. Students then film a TV<br />

advertisement to persuade others of the benefits of their<br />

product and bioplastic.<br />

• As stated on ACARA, processed materials are ‘Products<br />

of physical matter that have been modified from natural<br />

materials by human intervention or that do not occur at<br />

all in the natural environment, but have been designed<br />

and manufactured to fulfil a particular purpose’. Examples<br />

include bricks, clothing, bread, gumboots, raincoats,<br />

furniture, jewellery, mobile phones and so on.<br />

• A natural material is one that exists in nature and has not<br />

been changed. Most natural materials come from plants<br />

or animals. Examples include wood, cotton, wool, stones,<br />

clay, feathers, shells and so on.<br />

Assessment focus:<br />

• Use students’ work from Step 5<br />

as a diagnostic assessment of<br />

their understanding of the terms<br />

natural and processed.<br />

• Observe the Reflection<br />

student’s ability to identify<br />

examples of natural and<br />

processed materials.<br />

Lesson 1<br />

Lesson plan<br />

Introduction:<br />

1. Display a digital copy of page 46 on a whiteboard. In pairs, students discuss why they think the<br />

items are grouped as they are. Al<strong>low</strong> five minutes for discussion then write students’ suggestions<br />

on the board. QP<br />

Development:<br />

2. Reveal that the items in the ‘yes’ group are natural materials and those in the ‘no’ group are not<br />

natural materials; they are processed.<br />

3. In the same pairs, students brainstorm a definition for both natural material and processed material<br />

and list five examples of each, using a digital application like Popplet. Students share their ideas<br />

with the class so the teacher can write a class definition that everyone agrees with, to add to a word<br />

wall. QP C<br />

4. As a class, go through the items shown on page 47. Students suggest what item is missing from<br />

the natural column for the jumper (wool), and from the processed column for the gold (earrings,<br />

necklace etc). PA<br />

5. In pairs, students search the classroom or go outside to take photographs of 10 items and classify<br />

them as natural or processed. They then write or draw an example of what the cor<strong>res</strong>ponding<br />

natural or processed material would be, as shown on page 47. Students may wish to use a digital<br />

application like Keynote ® or ShowMe to p<strong>res</strong>ent their information. Pairs can test each other<br />

by showing each other their photographs to classify as natural or processed, and suggest a<br />

cor<strong>res</strong>ponding natural or processed material. PC PA C<br />

Differentiation:<br />

• Less capable students can work together and find five items to photograph.<br />

• More capable students can work individually to complete the task and <strong>res</strong>earch online to find<br />

other examples of natural and processed materials.<br />

Reflection:<br />

6. Students share one item they photographed and explain if it is natural or processed. Students<br />

also explain what natural material the item is derived from or what the item can be processed into.<br />

Clarify any misconceptions. C<br />

• Questioning and predicting QP<br />

• Planning and conducting PC<br />

• Processing and analysing data and information PA<br />

• Communicating C<br />

<strong>Science</strong> as a Human Endeavour:<br />

• Students make predictions about the properties of wool.<br />

• Students describe the relationship between the properties<br />

of a natural material and the product it is processed into.<br />

Technology/Engineering/Mathematics links:<br />

• investigating how the properties of wool affect the<br />

behaviour of a product<br />

• investigating fibre production of wool<br />

• scanning a QR code linked to a video<br />

• measuring length in centimet<strong>res</strong> and millimet<strong>res</strong><br />

• measuring temperature in degrees<br />

• using a stopwatch to track time in minutes<br />

Background information<br />

• A material’s properties are those characteristics that<br />

determine its suitability for a specific application. This<br />

knowledge helps in recognising what needs to be<br />

considered when a material is chosen for a particular use.<br />

• Wool itself is a natural fibre, however, when it is modified<br />

by humans, such as being made into a jumper, it becomes<br />

a processed material. The properties of the natural<br />

material still apply, but may also be modified if the jumper<br />

is mixed with other materials like leather or cotton.<br />

• Wool has properties including being soft, elastic,<br />

breathable, odour <strong>res</strong>istant, warm and cool, anti-static,<br />

stain <strong>res</strong>istant, anti-wrinkle, fire <strong>res</strong>istant and sun safe. This<br />

makes it ideal for purposes such as clothing and bedding.<br />

Lesson 2<br />

Lesson plan<br />

Introduction:<br />

1. Display the cartoon at to discuss. What if your clothes were made<br />

from grass? Why would this be a good idea? Why would it be a bad idea? Is grass a natural or<br />

processed material? QP<br />

Development:<br />

2. What other natural materials do we use to make clothes? Discuss natural material examples. What<br />

are some properties of these materials? What properties do clothes need to have? In pairs, students<br />

list examples and their properties in a table. QP<br />

3. As a whole class or in pairs, students watch a video about wool (a common natural material) at<br />

or scan the QR code on page 50. They then list the properties they<br />

think wool has and how this makes it useful. Alternatively, students can add wool to their table from<br />

Step 2 and list its properties. QP PA<br />

4. Students conduct tests to confirm the actual properties of wool, using page 51. Provide the class<br />

with equal-length pieces of 100% wool yarn or combed wool, easily obtained from craft shops such<br />

as Spotlight . Place pieces of wool at stations, for small groups to test five properties: flexibility,<br />

elasticity, water <strong>res</strong>istance/absorption ability to keep warm/cool. Students use a digital application<br />

or website to graph <strong>res</strong>ults of temperature, such as the graphing website at . PC PA<br />

Differentiation<br />

• Less capable students can use the graph template on page 52.<br />

• More capable students can test alternative methods of wrapping the cup with wool to see if<br />

adjusting this variable has any effect on <strong>res</strong>ults.<br />

Reflection:<br />

5. As a class, students share the properties of wool they investigated and compare it to the properties<br />

listed at . Discuss how they could test all of the properties listed. E<br />

C<br />

6. Students differentiate between natural and processed wool products. Ensure they understand<br />

that even though wool is a natural fibre and possesses these properties, it becomes a processed<br />

product when it is altered from its raw state. Is a wool jumper totally natural? What makes it<br />

processed? QP C<br />

<strong>Science</strong> as a Human Endeavour:<br />

• Students make predictions about the properties and uses of cotton<br />

and polyester.<br />

• Students describe the relationship between material properties and<br />

their uses for everyday clothing.<br />

• Students discuss why clothing designers select appropriate materials.<br />

• measuring length in centimet<strong>res</strong> and millimet<strong>res</strong><br />

• investigating how the properties of cotton and polyester affect the<br />

behaviour of clothing<br />

• investigating fibre production of polyester<br />

Background information<br />

• A material’s properties are those characteristics that determine<br />

its suitability for a specific application. This knowledge helps in<br />

recognising what needs to be considered when a material is<br />

chosen for a particular use.<br />

• As stated on ACARA, processed materials are ‘Products of physical<br />

matter that have been modified from natural materials by human<br />

intervention or that do not occur at all in the natural environment,<br />

but have been designed and manufactured to fulfil a particular<br />

purpose’. A natural material is one that exists in nature, unchanged.<br />

• Polyester is made from petroleum; it is basically a plastic fabric. It is<br />

used in clothing because it is very strong and durable, lightweight,<br />

wrinkle <strong>res</strong>istant, stretchable, quick drying, retains its shape and<br />

is easily washed and dried. The disadvantages are that it is nonbreathable,<br />

sticks to skin and can melt easily. It also harbours<br />

bacteria, causing odours.<br />

• Cotton is a natural fibre and is used in clothing due to its ability<br />

to breathe and keep skin cool. It also inhibits the growth of<br />

odour-causing bacteria. It holds moisture and is not as durable as<br />

polyester as it may shrink and wear out faster. It is also generally<br />

heavier than polyester fabric.<br />

Lesson plan<br />

Introduction:<br />

1. Pass around an item of clothing or piece of fabric made from polyester for students to feel and<br />

guess what it might be made from. Do the same for a piece of cotton fabric. Is it made from natural<br />

or processed material? List students’ predictions. QP<br />

2. Explain that the material is polyester and it is a synthetic material made from petroleum, and that<br />

the other piece of fabric is made from cotton. What does synthetic mean? QP<br />

Development:<br />

3. Display the cartoon from . In pairs, students discuss its meaning<br />

using the guiding questions on page 55. QP<br />

4. In pairs, students use page 55 to discuss cotton and polyester, and predict which type of gym<br />

clothes would trap the most odour. They then scan the QR code or go to the URL to read the article<br />

and summarise the findings. QP PC<br />

5. Students conduct their own tests using cotton and polyester, to assess the properties of elasticity,<br />

water <strong>res</strong>istance/absorption, static and strength. Students use page 55 to record <strong>res</strong>ults, as well as<br />

drawing their own table within the columns, to record measurements for elasticity. PC PA<br />

Differentiation<br />

• Less capable students can create audio recordings to describe their observations from the<br />

experiments instead of writing a description.<br />

• More capable students may test an additional property of their choice, and decide how to<br />

conduct the test.<br />

Reflection:<br />

6. Based on the science article and their test <strong>res</strong>ults, students individually summarise which type of<br />

fabric they would prefer to wear to the gym and why. Would you combine both materials? What<br />

are the advantages of each fabric? What are the disadvantages? Which is better? Do we need both<br />

types of fabric? C<br />

• Australia’s waste management consists of a recycling bin, a<br />

green bin and a general rubbish bin. The general rubbish<br />

ends up at a landfill site where it is buried between layers<br />

of soil, to decompose over time; however, not all materials<br />

thrown in general waste decompose. Plastic shopping<br />

bags are the worst culprit, along with takeaway coffee<br />

cups, cigarette butts, clothing and so on.<br />

• Biodegradable means that a material can decompose<br />

through bacteria or living organisms. Generally, more<br />

natural materials will be able to biodegrade.<br />

Note: This lesson will conclude after a two-week experiment so time should be allocated accordingly.<br />

Introduction:<br />

1. Play the video about rubbish at as a provocation. In pairs or small<br />

groups, students discuss the fol<strong>low</strong>ing questions: What does this picture show? What kinds of<br />

materials can you see in the rubbish? Where does your rubbish go when it gets collected? Does the<br />

type of material affect what happens to your rubbish? QP<br />

Development:<br />

2. Display the image of three bins at . Students suggest materials that<br />

can go in each. How does the property of each material affect which bin you put the material in?<br />

What materials are recyclable? QP<br />

3. As a class, play the interactive game at , which<br />

involves sorting rubbish into the correct bin. Emphasise the type of material of each item. Is it<br />

natural or processed? What are the properties of glass, aluminium etc? QP PA<br />

4. What happens to the rubbish we throw into the general waste bin? Where do these materials go?<br />

Watch a BTN video about landfill at . This video explains that landfill<br />

is where our non-recyclable rubbish goes. Students summarise what they learnt from the video<br />

about how a landfill works. PC C<br />

5. How can knowing the properties of materials help us solve the problem of landfill rubbish? Do all<br />

materials decompose in the landfill? What does biodegradable mean? In small groups, students<br />

conduct an investigation into the ability of materials to break down in soil, fol<strong>low</strong>ing the experiment<br />

on page 61. You may wish to show the beginning of the video at ,<br />

as a demonstration of how to conduct the experiment. Stop the video at 2:23, so the <strong>res</strong>ults aren’t<br />

revealed. Provide students with an assortment of materials to test, including plastic shopping bags,<br />

fabric from old clothes or tea towels, egg shells, cardboard, food scraps such as apple co<strong>res</strong> or<br />

banana skins, tissues, plastic lids, aluminium cans and anything else that may end up in the rubbish.<br />

Students will then need to find an area in the soil to bury their items. Note: It may be useful to place<br />

a stake or identifier in the ground so students remember where their items are when it comes to<br />

digging them up. PC PA C<br />

Differentiation:<br />

• Less capable students can draw diagrams or orally describe their experiment <strong>res</strong>ults, using a<br />

Background information<br />

• Plastic is a useful synthetic material made from petroleum.<br />

It is used in a variety of ways and has many purposes and<br />

properties. It can be flexible, like food packaging, or rigid<br />

like a PVC pipe. It is waterproof, durable, light, able to float<br />

and is relatively cheap to produce.<br />

• Plastic does not easily break down as it is made to be<br />

durable and long-lasting. Therefore, it should be recycled<br />

whenever possible to avoid ending up in landfill where<br />

it will not biodegrade, and avoid being washed into<br />

waterways where it will float around for years and break<br />

down into smaller plastic pieces which are harmful to<br />

marine life.<br />

• The Great Pacific garbage patch (also known as a gyre), is<br />

one of five in the oceans. It is a collection of broken down<br />

plastic pieces that collect in certain spots due to currents.<br />

See this video for more information on gy<strong>res</strong>: .<br />

• Bioplastics are another option to reduce plastic pollution.<br />

The properties of bioplastic make it biodegradable as it is<br />

made from plant-based products such as corn starch.<br />

Assessment focus:<br />

• Use pages 64 and 65 as a<br />

2. Recall from the previous lesson how plastic materials may not decompose or biodegrade. What<br />

did you predict would happen when you buried plastic materials in the soil? What are some other<br />

properties of plastic? Is plastic natural or synthetic? Discuss other properties that plastic may<br />

have and make a class list. This can include words such as hard, transparent, flexible, durable,<br />

waterproof, lightweight, able to float, colourful, not biodegradable, recyclable. QP<br />

3. Display a collection of plastic items around the classroom for small groups to investigate, such as<br />

toothbrushes, spatulas, water bottles, polystyrene, shampoo containers, fishing nets, plastic ropes<br />

or fishing line, plastic packaging and wrappers. Alternatively, al<strong>low</strong> students to collect a variety of<br />

plastic rubbish from the school grounds or recycling bins. Students investigate, test, record and<br />

Natural and processed materials have a range of physical properties that can influence their use<br />

(ACSSU074)<br />

Indicators<br />

• Identifies examples of natural and processed materials.<br />

• Describes properties of natural fib<strong>res</strong> like wool and cotton, and of a processed fibre like polyester.<br />

• Identifies and describes which materials are suitable for a particular purpose.<br />

• Describes what biodegradable means and how this property is beneficial to waste management.<br />

• Identifies materials that are not biodegradable.<br />

• Identifies products made from plastic and the properties that make plastic a useful material.<br />

• Describes why plastic is harmful to the ocean and why this should influence the use of bioplastic or<br />

other environmentally-friendly materials to make products.<br />

Answers<br />

Pages 67 and 68<br />

1. Natural: wool, cotton, wood, silk, shells, feathers, bamboo, rocks, gold<br />

Processed: bricks, table, rug, jumper, gumboots, T-shirt, jewellery<br />

2. Suggested answers include: soft, elastic, warm and cool, flexible, water-<strong>res</strong>istant. Useful for<br />

clothing, bedding.<br />

3. Polyester is durable, stretchable, wrinkle-<strong>res</strong>istant and quick-drying, while cotton is breathable and<br />

keeps skin cool, is heavy and absorbs moisture. Polyester harbours bacteria, while cotton does not.<br />

4. Wrap a sandwich: plastic cling wrap or ziplock bag, because it is waterproof and flexible.<br />

Make a basketball stand: metal or wood, because it is strong and durable.<br />

Make a bungee jump cord: rubber, because it is elastic and stretchable.<br />

Pack a p<strong>res</strong>ent to send by post: cardboard, because it is tough but lightweight.<br />

5. (a) Biodegradable means a material is able to be broken down by bacteria or living organisms<br />

over time.<br />

(b) Biodegradable materials are better for waste because objects in landfill could break down and<br />

not pollute the surrounding areas. If objects made from biodegradable material found their<br />

way into the waterways and oceans then this would be less harmful to marine life and they<br />

would break down and not contribute to garbage patches in the ocean.<br />

(c) plastic, metal, synthetic fabrics, coffee cups, cigarette butts, shopping bags<br />

6. (a) Plastic is durable, lightweight, cheap, water <strong>res</strong>istant, flexible or rigid (depending on type of<br />

plastic), floats easily. Products include pipes, bags, food packaging, storage containers.<br />

(b) Plastic is toxic because it is a synthetic material, and it does not biodegrade easily as it is made<br />

to be durable. In the ocean, plastic breaks down into smaller plastic pieces but never fully<br />

biodegrades. Marine life eat the plastic and humans eat the marine life.<br />

Bioplastics<br />

<strong>STEM</strong> project overview<br />

Students make their own bioplastic and create a suitable product from it.<br />

Concepts overview:<br />

<strong>Science</strong><br />

• Apply knowledge of properties of materials and plastics and suitable uses.<br />

• Plan and conduct an experiment to create bioplastic, including writing a hypothesis, listing<br />

materials and the procedure, and using materials and equipment safely.<br />

• Draw/write about <strong>res</strong>ults and compare <strong>res</strong>ults to predictions.<br />

• Communicate the observations of the <strong>res</strong>ulting bioplastic.<br />

Technology/Engineering<br />

• Plan production steps collaboratively.<br />

• Test the appropriateness of bioplastic for a product.<br />

• Investigate the properties of bioplastic.<br />

• Use bioplastic to create a designed solution.<br />

• Evaluate design ideas.<br />

• Collect data from online sources.<br />

• Use a digital application to record a video.<br />

Mathematics<br />

• Use scaled instruments to measure ingredients to make bioplastic.<br />

Alternative project ideas:<br />

• How would you solve the trash problem? Students watch the video about trash in the future<br />

at and create a waste management system for a new town,<br />

that sorts materials according to their properties. They then draw a design and create a digital<br />

p<strong>res</strong>entation of the waste management system plan.<br />

• Students create a model outfit for a fireman or for another special purpose, made from natural<br />

fib<strong>res</strong> or other appropriate materials. Students can use a selection of materials with assigned<br />

prices so they can work within a budget and calculate what they can afford.<br />

• Students create a compost bin that will break down materials and label it with the types of<br />

acceptable materials. They then create an infomerical to be shown to the school or uploaded to<br />

the school website, explaining then bin and how it works.<br />

<strong>STEM</strong> project:<br />

Teacher notes<br />

Students create bioplastic as an alternative to plastic, and design and create a product with the<br />

bioplastic material. They then persuade others of its benefits by filming a TV advertisement.<br />

Estimated duration: 4 weeks<br />

1. Introduce the project<br />

• Display page 72 and read as a class.<br />

• Watch a video to introduce the topic of bioplastic and the task ahead . What is bioplastic?<br />

2. Investigate<br />

• Students revise the properties and uses of plastic.<br />

• In their groups, students watch a video about how to make bioplastic at , and an example of a created product , fol<strong>low</strong>ing<br />

the project steps on page 73.<br />

3. Design, plan and manage<br />

• Students write and develop an experiment plan, based on the video viewed previously.<br />

Display page 74 on the whiteboard as a guide, or less capable students may use a copy of<br />

it as their plan. The video outlines the materials: 1 tablespoon tapioca starch, 4 tablespoons<br />

water, 1 teaspoon vinegar, 1 teaspoon glycerin, some foil, a saucepan, tray and a spatula. A<br />

stovetop will be required for this experiment so groups should be organised and monitored<br />

accordingly.<br />

• Students compile a list of plastic products, or create a collage using a digital application like<br />

Popplet.<br />

• Students then choose a product they want to create with bioplastic and write a list of the<br />

properties that the product needs to have in order to fulfill its purpose.<br />

• Once the type of product is decided, students then sketch a design and label the parts and<br />

materials. They will need to consider whether to combine another material, like fabric as shown<br />

in the video, to add an extra property to the product.<br />

• Students manage their group and allocate tasks to team members, then collect the required<br />

materials.<br />

4. Create<br />

• Students create their bioplastic according to their experiment plan.<br />

• Students then mold it into the desired product shape.<br />

5. Evaluate and refine<br />

• Students review and amend their bioplastic ingredients if they need to make more or less.<br />

• Students may need to amend how they create a mold, or how they shape their bioplastic into<br />

the correct shape required.<br />

• Students must ensure that the plastic does what it is intended for; e.g. waterproof if used as a<br />

bottle, or flexible if used as a bag.<br />

6. Communicate<br />

• Students film a TV advertisement to persuade others that their product is a better alternative to<br />

plastic. They will need to mention the properties of their bioplastic product and its use.<br />

The problem<br />

Project brief<br />

BIOPLASTICS<br />

You are part of a team of materials scientists who are looking at a new type<br />

of ‘plastic’ that is biodegradable—called bioplastic. How can you make it as<br />

durable and useful as synthetic plastic? What product can you make with it?<br />

The task<br />

Create a biodegradable material, similar to plastic, that can be used for a<br />

product. You will then create a TV advertisement to sell your product based on<br />

its properties.<br />

Things to consider<br />

• You must work in groups of 2–3 students.<br />

• You must fol<strong>low</strong> the experiment to create the bioplastic. You may add other<br />

materials to the bioplastic to enhance its properties.<br />

• You must describe its properties and its use.<br />

• You must use the bioplastic to create a product that is normally made with<br />

plastic. You will need to consider the purpose of the product and what<br />

properties it needs to have.<br />

• You must create a TV advertisement that persuades people to buy your<br />

bioplastic product rather than synthetic plastic.<br />

<strong>STEM</strong> project<br />

Form the landforms<br />

Students explore what a geologist is and how they examine<br />

rocks to understand what changes Earth’s surface has gone<br />

through. Students conduct their own dig in the school yard, and<br />

photograph and examine rocks, in an attempt to classify them.<br />

Students explore what soil is made up of and the three types—<br />

sand, silt and clay. Students investigate actual soil samples to<br />

record information about colour, texture, grain size and ability to<br />

absorb water, as well as conduct an experiment to separate soil<br />

into its components.<br />

Students conduct online <strong>res</strong>earch to determine what weathering<br />

is and rep<strong>res</strong>ent the information in a graphic organiser of their<br />

choice. Students then demonstrate the weathering process of<br />

freeze-thaw by creating a rock from modelling clay, filling the<br />

inside with water, freezing and photographing the <strong>res</strong>ults.<br />

Students look at examples of landforms and predict how these<br />

were formed. Students then conduct online <strong>res</strong>earch by watching<br />

a video that explains the difference between weathering and<br />

erosion. Students then demonstrate erosion by wind, water and<br />

ice (glaciers) and compare their demonstrations to videos online.<br />

Students explore the effects of extreme weather, such as<br />

floods and storms, on coastlines or areas surrounding natural<br />

waterways. Students conduct an experiment to test the effects of<br />

erosion when only sand is p<strong>res</strong>ent, when there are plants in the<br />

sand, and one other variable of their choice that is added to the<br />

sand. Students recreate storm waves and film the <strong>res</strong>ults, in order<br />

to offer the best solution to protect the coastline from erosion.<br />

Students use internet <strong>res</strong>earch to understand how humans<br />

contribute to erosion through defo<strong>res</strong>tation, mining, construction<br />

and agricultural practices. After watching a video of school<br />

students investigating a local area subject to erosion, students<br />

explore their own local area and create a short documentary<br />

about the way humans have contributed to erosion and how they<br />

may be able to help.<br />

Students answer questions relating to what rocks and fossils can<br />

reveal about Earth’s past, the components of soil and how sand<br />

is created, what weathering and erosion are, and the effects of<br />

extreme weather and humans on erosion.<br />

Students use their knowledge of how landforms are created and<br />

change over time, to demonstrate the process using gelatin/<br />

sand landforms and warm water. A video is then created by<br />

adding sound effects, music and a voice over, as well a table of<br />

measurements taken of the various landforms.<br />

many layers of rock, with numerous shapes, colours,<br />

sizes and textu<strong>res</strong>. There are three groups of rock, based<br />

on how they are formed—sedimentary, igneous and<br />

metamorphic. This is covered in more detail in the <strong>Year</strong> 8<br />

Lesson 1<br />

Lesson plan<br />

Introduction:<br />

1. Display either the image at or a similar image of a geologist. In<br />

pairs, students discuss questions including: What do you think geology is? What does a geologist<br />

do? What is a rock? How can rocks be used to show the changes in Earth’s surface? QP<br />

Development:<br />

2. Watch the short video Secrets of the Earth are hidden in rock at to<br />

introduce geology.<br />

3. Students are again p<strong>res</strong>ented with the question. What is a geologist? Use their suggestions to write<br />

a class definition. Read through an explanation of rocks at and write<br />

a class definition. C<br />

4. Display the images on page 82 on the whiteboard. In pairs, students discuss and predict how<br />

geologists use rocks and fossils to see changes in Earth’s surface. What comes next in image A? Are<br />

the bottom layers older or younger rock? What are the animals bones you can see p<strong>res</strong>erved in the<br />

rock in image B? (Fossils). Look at the bottom layer in image C. What fossils can you see? What was<br />

on Earth millions of years ago by looking at the bottom layer? How else do the layers of rock look<br />

different? Show students images of the appearance of rock layers from different landforms such as<br />

ocean, lake, desert, river at . Note: Click on each image to enlarge it.<br />

QP PC<br />

5. In pairs, students collect a selection of tools from the classroom that can do a similar job to a<br />

geologist’s tools. This could include a soft paintbrush, magnifying glass, a notebook, ziplock bags,<br />

garden trowels, forks, spoons and so on. Students head outside to collect a sample of rocks.<br />

Alternatively, you may provide a tray of sand and hide a selection of rocks, shells and mineral<br />

stones. Students take a photograph of the rocks and use page 83 to record their observations.<br />

They then compare their investigation to the rocks shown on the website from Step 4. Students also<br />

indicate on a map where the items were found. If using a tray instead, students record where the<br />

item was found in the sand tray. Ensure students complete Question 1 on page 83 before starting<br />

their investigation. QP PC PA C<br />

Differentiation<br />

• Less capable students can work together in a small group with an adult helper to guide their<br />

investigation.<br />

• More capable students can conduct further <strong>res</strong>earch into rock classification and what kinds of<br />

rocks exist. (This topic is explored in depth in the <strong>Year</strong> 8 <strong>Science</strong> curriculum).<br />

Reflection:<br />

6. Students share any observations about the rocks they found and what clues they offer about what<br />

Earth used to be like. What can a rock tell you about Earth? Did you find the kinds of rocks you<br />

predicted you would find? What did the rocks you found tell you? What would you change about the<br />

investigation? What might you find if you dug deeper? PA E C<br />

Lesson 2<br />

Lesson plan<br />

Introduction:<br />

1. Go to the Soils of Australia map at and display it to the class. Focus<br />

on your local area or state. Ask students what they are looking at. Why are there different colours all<br />

over the land? What might it mean? What is this a map of? What do the numbers refer to? QP<br />

Development:<br />

2. Reveal to students that this is a soil map. What is in soil? Is soil the same all over Australia? Why<br />

would there be different soils? Students use a digital application such as Popplet to create a<br />

concept map of ideas about what they think soil is and its components. Students share one idea<br />

from their concept map. QP PA<br />

3. Display the pie chart at which shows the components of soil—<br />

minerals (sand, silt and clay), organic matter, air and water. Students compare their ideas of what is<br />

in soil to the information in the pie chart. PC PA<br />

4. Display a selection of different soil types at stations around the classroom. In pairs, students<br />

observe using a magnifying glass and record information about each soil type using page 86.<br />

Students look at characteristics such as size, texture, colour and absorption. Limit students to five<br />

minutes at each station. What does the soil feel like? What is different about each type of soil?<br />

PC PA<br />

5. Watch a video about the three soil types at to see if students<br />

recognise any similar characteristics to the soils they observed during Step 4.<br />

6. Students act as soil scientists by collecting a soil sample from the schoolyard and analysing it to<br />

see if they can identify whether it is made up of sand, silt or clay. Instruct students to dig a narrow<br />

but relatively deep hole and place the sample into a jar or plastic bottle (use a funnel if necessary).<br />

Alternatively, lengths of PVC pipe can be placed in the soil and removed to collect soil samples.<br />

Students add water to the soil sample in the bottle, shake it and then leave it to settle, observing<br />

the changes regulary. This may take a couple of hours, so you may wish to conduct the <strong>res</strong>t of the<br />

lesson in the afternoon or even the next day. Students should be able to see layers form, with larger<br />

particles at the bottom and finer particles at the top. Results can be recorded using page 87. Can<br />

you tell if your soil sample has more sand, silt or clay? PC PA<br />

7. Students work out a rough fraction for each of the different layers of soil (if any), and add it to their<br />

diagram on page 87. PA<br />

Differentiation<br />

• Less capable students can pair up and work with the teacher to conduct the soil sample<br />

collection and analysis.<br />

• More capable students can obtain another sample from a different location to analyse, or obtain<br />

a sample from deeper be<strong>low</strong> the surface. Students may also wish to collect samples from home<br />

and use them for comparison.<br />

8. As a class, discuss the <strong>res</strong>ulting layer formations and any differences between groups/pairs or any<br />

problems encountered with the soil collection. If you dug deeper, would the soil be different? What<br />

would you change about the investigation? Did everyone collect a soil sample from the same place?<br />

Why did the layers form? E C<br />

9. Refer back to the map from Step 1, showing different soils around Australia. How does knowing<br />

what type of soil is on the land help farmers? QP<br />

• Planning and conducting PC<br />

• Processing and analysing data and information PA<br />

• Communicating<br />

<strong>Science</strong> as a Human Endeavour:<br />

C<br />

• Students make predictions about how soil is created<br />

and what breaks down rocks on Earth’s surface.<br />

• Students describe the relationship between weathering<br />

and the changing surface of Earth.<br />

Background information<br />

• The rock soil comes from is often referred to as parent<br />

rock. Parent rock is the main factor in determining<br />

the texture of soil, whether it is acidic or basic and<br />

whether it is rich in nutrients. Climate is another<br />

important factor.<br />

• Natural processes can take more than 500 years to<br />

break down two centimet<strong>res</strong> of topsoil.<br />

• Weathering is the breaking down of rocks and soil on<br />

Earth’s surface. There are three forms of weathering—<br />

physical, chemical and biological. See pages 6, 7 and<br />

8 of the BBC Bitesize website at .<br />

• Physical weathering occurs when the temperature of<br />

the rocks constantly changes, such as a freeze-thaw<br />

process, or by repeated exposure to sun, wind or rain<br />

which has an exfoliation effect on the rock.<br />

• Chemical weathering is caused by rainwater which<br />

becomes slightly acidic as it dissolves the carbon<br />

dioxide in the air as it falls.<br />

• Physical weathering is caused by living organisms<br />

such as the roots from a tree cracking the surface, an<br />

animal that burrows into a rock, or algae that attaches<br />

itself to a rock and produces a chemical that wears<br />

away the surface.<br />

Lesson plan<br />

Introduction:<br />

1. Show a selection of images of different-coloured sandy beaches to engage students; red sand<br />

beach , black sand beach . How<br />

were these beaches made? What do you notice about the nearby rocks? Do you think the beaches<br />

always looked like this? In pairs, students discuss possible answers. QP<br />

Development:<br />

2. Pass a mortar and pestle, with rock salt in it, around the classroom for students to have a go at<br />

breaking down the rock salt. Discuss questions including: What do you think will happen to this<br />

rock salt if you grind it with the pestle? What will it look like? How might this be similar to how rocks<br />

become sand or soil? What acts as the 'pestle' in nature? QP<br />

3. Introduce the term weathering. Students <strong>res</strong>earch a definition online or go to , and write an agreed definition to place on a word wall. PC<br />

4. In pairs, students conduct their own <strong>res</strong>earch to explore how rocks undergo weathering by reading<br />

pages 6, 7 and 8 on the BBC Bitesize website at . Note: A QR code<br />

link to this website is provided on page 90 for students to scan as well as the URL. Students then<br />

create a graphic organiser or concept map using page 90, drawing their own graphic organiser, or<br />

using a digital application like Popplet or Book Creator. PC PA C<br />

Differentiation<br />

• Less capable students can draw pictu<strong>res</strong> to explain the weathering process, or retell it orally<br />

using the audio recording function on an application such as Book Creator.<br />

• More capable students can <strong>res</strong>earch other websites, such as to<br />

compare information on weathering, and add any more information.<br />

5. Students recreate the physical weathering process, freeze-thaw, to demonstrate how it works.<br />

Students use modelling clay to form a rock and then create a well in the middle which is filled<br />

with water. Seal the hole with clay and place in the freezer overnight. In the morning, students<br />

photograph the ‘rock’ which should have cracked to al<strong>low</strong> for the expanded frozen ice. Students<br />

should predict how the rock will look by drawing a diagram, and then compare the predicted<br />

diagram to the photograph taken after being in the freezer overnight. They may use page 91 to<br />

draw/paste their images, or use a digital application like Popplet or Seesaw instead. PC PA<br />

Reflection:<br />

6. Watch the video How mountains turn to dust at , which summarises<br />

the process of weathering rock and how it changes Earth’s surface. Did you know that it took so<br />

many years to break down rock? What do you think this means for the future? What will Earth look<br />

like? What do you think is the most powerful weathering tool? C QP<br />

<strong>Science</strong> as a Human Endeavour:<br />

• Students make predictions and observations about the best<br />

way to decrease the impact of erosion on the coastline.<br />

Technology/Engineering/Mathematics links:<br />

• using a digital video recorder to document and play back<br />

<strong>res</strong>ults<br />

• creating an investigation plan using a digital application<br />

such as Book Creator<br />

Background information<br />

• Extreme weather is weather that is different from the usual<br />

pattern. This includes floods, storms, drought, a heat wave<br />

or a cold snap. These all have an impact on the Australian<br />

landscape.<br />

• Floods occur when there has been heavy rainfall, often<br />

associated with cyclones and storms, which overf<strong>low</strong>s on<br />

normally dry land. The water can overf<strong>low</strong> from rivers, lakes,<br />

creeks and other natural waterways.<br />

• Erosion is the taking away of the broken-down rocks and<br />

sand. In the instance of the 2016 storms across the eastern<br />

coast of Australia, the king tide caused the waves and ocean<br />

water to be even more intense so the erosion was more<br />

severe. Major changes to the appearance of the coastline<br />

occurred.<br />

Assessment focus:<br />

• As a formative assessment<br />

use the experiment plan to<br />

check students’ understanding<br />

of how to plan, conduct and<br />

record <strong>res</strong>ults.<br />

• Observe the <strong>res</strong>ponses during<br />

the reflection to ascertain<br />

whether students understand<br />

how extreme weather such<br />

as a storm can change Earth’s<br />

surface by eroding the<br />

coastline, and what can be<br />

done to reduce the impact.<br />

SURFACE CHANGES<br />

Lesson plan<br />

Introduction:<br />

1. Click on several images showing flooding in Australia at and<br />

discuss as a class. What kind of erosion is happening in these pictu<strong>res</strong>? What do you notice about<br />

the colour of the water? Why is it that colour? What other extreme weather might cause erosion<br />

through water? QP<br />

Development:<br />

2. As a class, watch the video Storm erosion at , about the effects of the<br />

2016 storm on Australia’s eastern coastline. In small groups, students discuss how wind and water<br />

erosion worked to destroy the coastline, and then report an explanation back to the class. PC C<br />

3. Students conduct an experiment based on the work the children were doing in the video, by<br />

comparing the effects of erosion using three variables: Variable 1 is sand only; Variable 2 is sand<br />

with plants; and Variable 3 is white sand and something of the students’ own choosing that they<br />

think may act as a preventative to erosion. It could include options such as shells, gravel, grass,<br />

wood posts and so on. See page 99 for experiment details. PC C<br />

4. Students write their experiment plan including a hypothesis, variables, procedure and <strong>res</strong>ults.<br />

While conducting the experiments, students film the effects of the ‘storm’ on the three types of<br />

‘coastline’. They can then review the footage and write their final conclusion. PC PA C<br />

Differentiation<br />

• Less capable students can use page 99 to plan their investigation and record <strong>res</strong>ults.<br />

• More capable students can create their own experiment plan as long as it includes a hypothesis,<br />

materials, method, <strong>res</strong>ults and conclusion.<br />

• All students may prefer to write a digital version of the investigation instead, using an<br />

application such as Book Creator.<br />

Reflection:<br />

5. Groups share their final conclusion about the best recommended practice to protect coastlines<br />

from storm erosion. Is it what you predicted? Students may also compare different options tested<br />

for Variable 3 and review the footage of the <strong>res</strong>ults to determine the overall best option. PA C<br />

Teacher notes<br />

<strong>Science</strong> inquiry focus:<br />

How does human activity contribute to erosion? How can<br />

humans help reduce erosion?<br />

<strong>Science</strong> Inquiry Skills:<br />

• Questioning and predicting QP<br />

• Planning and conducting PC<br />

• Processing and analysing data and information PA<br />

• Communicating C<br />

<strong>Science</strong> as a Human Endeavour:<br />

• Students investigate how science helps people understand<br />

the impact of human activity on erosion.<br />

Technology/Engineering/Mathematics link:<br />

• using a digital application like Popplet to organise<br />

information<br />

• conducting internet <strong>res</strong>earch and rep<strong>res</strong>enting information<br />

and images in a PowerPoint ® or Keynote ® p<strong>res</strong>entation slide.<br />

• creating a short documentary using a digital application such<br />

as iMovie ® and sharing it via email or uploading to a website<br />

Background information<br />

• Research has shown that humans make a significant<br />

contribution to erosion, and may be as much as 15 times<br />

more powerful than the impact of natural erosion.<br />

• Humans mostly increase erosion because of agriculture<br />

and poor farming practices which strip the soil quicker<br />

than Mother Nature can create new soil. Other factors are<br />

defo<strong>res</strong>tation, mining and development or construction.<br />

These all mean that sand and rocks are manually removed<br />

from Earth’s surface.<br />

• Humans also have the power to help reduce the impact<br />

of their erosion of Earth’s surface. This can be done by<br />

revegetating areas so that plant roots can act as a barrier to<br />

erosion.<br />

Assessment focus:<br />

• Use the slide show in Step 3<br />

students’ understanding of<br />

the ways humans contribute<br />

to erosion as well as ways they<br />

Lesson 6<br />

Lesson plan<br />

Introduction:<br />

1. As a class, recall what erosion is (the taking away/movement of broken-down sand and rock by<br />

wind, water and glaciers). How might humans be another force of erosion? In pairs, students<br />

brainstorm examples of human activities they think may contribute to erosion, and compile words<br />

and pictu<strong>res</strong> using a digital application such as Popplet. QP<br />

Development:<br />

2. Students investigate the ways that humans contribute to erosion by conducting internet <strong>res</strong>earch.<br />

Students can begin their search at . PC<br />

3. In pairs, students create a digital p<strong>res</strong>entation or slide show using an application such as<br />

PowerPoint ® or Keynote ® . Students should include a title/introduction page, a definition of<br />

erosion, a photograph demonstrating four types of human erosion as mentioned in the website<br />

(defo<strong>res</strong>tation, mining, development and construction, and agriculture), and a sentence explaining<br />

how humans move or take away the sand and broken-down rocks in each photograph. PA C<br />

Differentiation<br />

• Less capable students can use one website and write keywords and less complicated sentences<br />

instead.<br />

• More capable students can conduct further <strong>res</strong>earch and use another website to gain more indepth<br />

information.<br />

4. As a class, view and discuss the video Hillside erosion: how to stop it at , which shows how a Natural Resources Management board in Willunga Hills,<br />

South Australia is helping reduce the impact of erosion caused by poor farming practices, by<br />

encouraging farmers to look after their land and revegetate areas near creeks. How did humans<br />

cause erosion in Willunga Hills? How are they trying to help stop erosion? PC<br />

5. In small groups, students locate and document a local example of how humans have caused<br />

erosion but also how humans can help reduce erosion. Students create a short documentary similar<br />

to the Hillside erosion video, incorporating a question-and-answer format. An application such as<br />

iMovie ® can be used. QP PA PC C<br />

Reflection:<br />

6. Students play their short documentary to the class, upload it to a school website or email it to<br />

classmates or family. As a class, discuss the different examples shown. Write a list of the different<br />

areas and the ways that humans have impacted each, and how people can help prevent future<br />

erosion. C<br />

Teacher notes<br />

<strong>Science</strong> knowledge<br />

Earth’s surface changes over<br />

time as a <strong>res</strong>ult of natural<br />

processes and human<br />

activity (ACSSU075)<br />

Indicators<br />

• Identifies that rocks and<br />

• Identifies soil<br />

composition and that<br />

soil types vary across<br />

• Identifies that rocks break<br />

down over long periods<br />

of time to create mineral<br />

soil.<br />

• Describes examples of<br />

physical, chemical and<br />

biological weathering.<br />

• Understands the<br />

difference between<br />

weathering and erosion.<br />

• Describes erosion due to<br />

wind, water and glaciers.<br />

• Describes how extreme<br />

• Identifies and describes<br />

how humans contribute<br />

to soil erosion and how<br />

they can also help s<strong>low</strong><br />

down the erosion process<br />

by re-vegetating.<br />

Answers<br />

Pages 103 and 104<br />

1. Teacher check. Possible answers include: the marking on a rock<br />

could indicate that water used to run over it like in a river, or a<br />

fossil of a fish may indicate that the land was once ocean.<br />

2. (b)<br />

3. False<br />

4. (c)<br />

5. Physical: changing temperature of rocks which cause cracks;<br />

wind, rain and waves act as an exfoliant over time, as the wind<br />

b<strong>low</strong>s sand particles and the rain and waves run over the surface<br />

of rock and wear it away over time; freeze-thaw process where<br />

cracks in rocks fill with water and freeze overnight which expands<br />

the crack and breaks the rock<br />

Chemical: rainwater which absorbs carbon dioxide in the air<br />

making it slightly acidic on rock, or actual acid rain that is formed<br />

when fossil fuels are burned and carbon dioxide and sulphur<br />

dioxide are released in the air and absorbed by rain on the way<br />

down<br />

Biological: any animals and plants that wear away rock such as a<br />

rabbit that burrows in a crack, a plant root growing in a crack, or<br />

humans repeatedly walking over a rock surface<br />

6. Weathering is the breaking down of rocks and erosion is the<br />

taking away of the broken-down particles by wind, water or<br />

glaciers.<br />

7. Teacher check drawings.<br />

Wind: winds b<strong>low</strong> and carry loose sand and soil away, which is<br />

how sand dunes are formed<br />

Water: rivers, oceans, streams and other natural waterways f<strong>low</strong><br />

and take soil and broken down rocks with them<br />

Glaciers: ice moves down a mountain side and gathers soil and<br />

small rocks underneath it as it moves down. The glacier melts<br />

along the way as well, forming a f<strong>low</strong> of water which also collects<br />

soil and rocks off the mountain and deposits them at the bottom.<br />

8. Storms cause heavy rain and strong winds which lead to waves<br />

crashing into the coastline and carrying away more sand. Other<br />

examples of extreme weather students may provide include<br />

floods, droughts, heatwaves or cold snaps.<br />

9. Humans contribute to erosion of the soil through agricultural<br />

practices, defo<strong>res</strong>tation, construction/demolition and mining.<br />

10. Humans can help stop erosion by ensuring plants and trees are<br />

planted in the soil so the roots act as an anchor, holding the soil<br />

together and making it less likely to be carried away.<br />

<strong>STEM</strong> project overview<br />

Students create a landform scene and film a video showing how the landforms weather away and<br />

erode with water.<br />

Concepts overview:<br />

<strong>Science</strong><br />

• Plan and conduct a demonstration of weathering and erosion on landforms.<br />

• Observe and record changes in the height and shape of the landforms.<br />

• Rep<strong>res</strong>ent and communicate scientific information in the form of a video.<br />

Technology/Engineering<br />

• Plan a scene including different types of landforms.<br />

• Create molds or select appropriate mold shapes, and create landforms using a gelatine/sand<br />

mixture.<br />

• Use a video recording device or application to film how water weathers and erodes landforms.<br />

• Add music, sound effects and a table of data to a video using iMovie ® or a similar application.<br />

• Evaluate and revise the landform scene and video.<br />

Mathematics<br />

• Measure the height and width of landforms before and after ‘weathering’ and ‘erosion’, and<br />

record information in a table using a computer.<br />

Alternative project ideas:<br />

• Create a short movie from the point of view of a rock. How does it start its life? What journey does<br />

it go on? How does it change? Students may do this as a claymation video or a stop-motion video<br />

using real rocks and sand.<br />

• View a story about the Philippines floods at . Students then design<br />

a way to help minimise the effects of flooding on the landscape and design a kind of barrier or<br />

protector.<br />

• Students act as reporters and interview a famous geologist, also played by a student. They need<br />

to write questions and answers about what the geologist has discovered about the changes to<br />

Earth’s surface and how they collect their evidence.<br />

The problem<br />

Project brief<br />

FORM THE LANDFORMS<br />

You are a junior geologist who needs to create a video for schoolchildren that<br />

demonstrates how erosion and weathering changes and shapes landforms and<br />

rocks.<br />

The task<br />

Create a scene with landforms made from<br />

sand and gelatin, and film what happens<br />

to the landforms and landscape as water<br />

weathers away at it and erodes the sand.<br />

Things to consider<br />

• You must work in groups of 2–3 students.<br />

• You must include at least four landforms in your scene.<br />

• The landforms must be made from a gelatine/sand mixture, using the recipe<br />

provided. You can choose or create your own molds depending on the<br />

shape or landform you are trying to achieve. You can add other featu<strong>res</strong> like<br />

trees or plants made from other materials.<br />

• You need to film a video and add a voice over explaining what happens<br />

when water weathers and erodes rock. The keywords erosion, weathering<br />

and landforms must be used.<br />

• Add music or sound effects to your video.<br />

• You will need to measure the height and width of your landforms before and<br />

after weathering and erosion and record the information in a table using a<br />

computer. You will then add the<br />

table to your video and explain<br />

what the data rep<strong>res</strong>ents.<br />

Alien forces<br />

Students define and revise what a push and pull force is<br />

before conducting an investigation into how the amount of<br />

force affects the motion of an object based on an Angry birds<br />

concept and using a catapult.<br />

Students explore the direct force of friction and conduct an<br />

experiment using shoes with different types of surfaces and<br />

how these affect the performance in a tug-of-war game.<br />

This lesson focuses on gravity—one of the forces that acts<br />

from a distance. Students conduct four short experiments by<br />

rotating stations, including how different ramp heights affect<br />

how a ball rolls, how the distance at which a marble is dropped<br />

affects the force with which it drops, how a cup of water with a<br />

hole in it drops and how two equal-sized objects with different<br />

weights drop.<br />

This lesson focuses on two opposing forces of gravity and air<br />

<strong>res</strong>istance, which is a type of friction, by exploring how to make<br />

a parachute that will al<strong>low</strong> an egg to drop to the ground safely<br />

from a height.<br />

This lesson focuses on magnets—another force that acts from<br />

a distance. Students rotate through four magnetic challenges<br />

that demonstrate how magnets can act as a force that either<br />

repels or attracts objects.<br />

This lesson focuses on static electricity—the final force students<br />

will explore that acts from a distance. Students rotate through<br />

six stations that demonstrate the force in action, either as a<br />

force that repels or a force that attracts.<br />

Students answer questions, write information in a table and<br />

draw force diagrams to communicate what they have learnt.<br />

Students use their knowledge of how forces work from a<br />

distance to build a UFO, a hover base for it to move across,<br />

and a skyscape, to serve as a scene for a short movie.<br />

• Communicating C<br />

<strong>Science</strong> as a Human Endeavour:<br />

• Students make predictions about push and pull forces and<br />

what contact forces are.<br />

Technology/Engineering/Mathematics link:<br />

• making 3D cubes from paper (optional, or pre-made during<br />

• observing speed and the distance an object travels, without<br />

formal measurement<br />

Background information<br />

• Forces cause objects to speed up, s<strong>low</strong> down or change<br />

direction. The greater the mass of an object the more force<br />

is needed to start or stop it moving.<br />

• Forces move in a particular direction and are usually shown<br />

on a diagram with arrows, which show the direction in<br />

which the force is acting.<br />

• Direct or contact forces such as pushes, pulls and collisions<br />

are applied directly and transfer energy to an object. When<br />

a ball is kicked, energy from the foot is transferred to the<br />

ball, sending it in the direction and at the speed the player<br />

wants. When you throw a ball a similar transfer of energy<br />

occurs from your arm to the ball.<br />

• When a ball is bounced, a push force is applied and then<br />

when it hits the ground, the material of the ball enables<br />

it to be squashed as it hits the floor and then spring back<br />

into shape and release the stored energy to bounce back<br />

up.<br />

Assessment focus:<br />

• Use page 119 and observe the<br />

Reflection discussion to gauge<br />

the student’s ability to identify<br />

contact forces and how they<br />

Lesson 1<br />

Lesson plan<br />

Introduction:<br />

1. Display the concept attainment chart from page 118 on a whiteboard. In pairs, students discuss<br />

why they think the items are grouped as they are, and suggest three more examples of each (they<br />

are push and pull forces). Al<strong>low</strong> five minutes for discussion. The teacher can compile a list in a<br />

digital T-chart such as , or simply add them to the chart displayed<br />

on the whiteboard. QP PA<br />

Development:<br />

2. Discuss the examples listed and the concept of direct forces. Why do you think these forces are<br />

called direct forces? What is making contact in each example listed? What would make the force<br />

stronger? Also discuss which direction the force is going and draw arrows on the examples in the T<br />

chart. Which direction is the force acting? Is there more than one force? QP<br />

3. As a class, view the Angry birds game at . Students suggest what<br />

kind of force is applied to the slingshot, what force is at work on the bird and whether it is a contact<br />

force. What happens when you increase the force on the slingshot? How can you make the bird go<br />

faster or further? What happens to the bird when it hits the boxes? Why? Are all the forces contact<br />

forces? QP<br />

4. In pairs, students use page 119 to explore forces at work and how they affect speed (and therefore<br />

distance) of an object. Students conduct trials using a simple catapult system to replicate a version<br />

of Angry birds. They construct the catapult after watching a simple video at . Students use cubes made from paper (pre-made in a mathematics lesson) or whatever<br />

lightweight items are available such as pieces of foam, and place them in front of the catapult at<br />

different distances at which to aim the ‘bird’. By doing so, students learn to adjust the force of the<br />

push applied to the catapult, which determines the speed as well as the distance that the ‘bird’<br />

travels. PC<br />

5. Students use an iPad ® to record the ‘bird’ in motion, and label it with arrows using an application<br />

such as ShowMe. The arrows should show the direction in which the forces are moving. PA PC<br />

6. Students can view each others’ labelled videos and compare the arrows to their own. Did you draw<br />

one arrow or more than one? PA<br />

Differentiation<br />

• Less capable students can work together with teacher support, and use various objects as<br />

targets rather than making their own cubes. They may also require further revision of push and<br />

pull forces by watching a video at and taking the assessment<br />

quiz at the end.<br />

• More capable students can write further examples of everyday activities that involve forces, and<br />

label them with directional arrows indicating the direction and strength of the forces involved.<br />

7. As a class, students discuss what the arrows rep<strong>res</strong>ent and demonstrate using their labelled video.<br />

C<br />

8. Students relate the concept to other everyday activities. What other objects in everyday life do you<br />

apply a force to? Is it a push or a pull force? How do you make it move faster? Does it travel further<br />

as well? How do you make the object come to a stop? Is it a direct force? C<br />

Background information<br />

• Friction is a direct contact force that opposes motion,<br />

making it more difficult for objects to move across a<br />

surface. Speed is inversely proportional to friction.<br />

• The type of surfaces, together with the force p<strong>res</strong>sing<br />

them together, determines the amount of friction.<br />

Examples include: rough carpet or smooth tiles; an<br />

empty trailer or one filled with sand; rubber-soled<br />

sports shoes or leather-soled dance shoes.<br />

• Friction is beneficial in everyday life, such as making<br />

walking possible due to the friction between a shoe<br />

and the ground, but it can be a nuisance by limiting<br />

movement, such as when trying to push heavy furniture<br />

across carpet.<br />

Lesson plan<br />

Note: Instruct students in their groups to bring in a sports sneaker, thong and d<strong>res</strong>s shoe for this<br />

experiment. Alternatively the teacher may supply one or two of each and use station rotations instead.<br />

Introduction:<br />

1. Display pre-prepared books or sticky notes to<br />

the class, with interleaved pages as shown in<br />

the diagram.<br />

Students think-pair-share the fol<strong>low</strong>ing questions: What do you think will happen when I turn this on<br />

its side and hold onto one end only? Why do you think that? What kind force is in action? QP<br />

Development:<br />

2. Introduce the term friction and show students a video of a tug of war at . Start the video at 7:19, and pause it at 8:57. Using a show of hands, students predict<br />

the winner and then explain why. Continue watching the video, then stop it at 9:20. What forces are<br />

being applied to the rope? What forces are being applied to the ground? What direction are the<br />

forces acting? Is it a push or a pull? What is friction? Note: If time al<strong>low</strong>s, students could play a quick<br />

game in order to feel the forces for themselves. QP<br />

3. In pairs, students use a whiteboard or an application on an iPad ® to draw a diagram indicating<br />

the directions the forces are moving in the tug-of-war activity. Display the top half of page 122 for<br />

students to compare their own diagrams to. PA<br />

4. Students hypothesise about which shoe would be the best, and use a show of hands to vote.<br />

Record the <strong>res</strong>ults as a tally on the whiteboard. In pairs or small groups, students conduct the<br />

experiment on page 123 to determine how different types of shoes move on a surface like in the<br />

tug-of-war game. QP PC<br />

5. Students individually complete page 124, and use an iPad ® to take a<br />

photograph of one shoe friction test and label it with arrows to indicate the<br />

direction of forces, using an application such as ShowMe or the edit feature<br />

in the Photos application. The labels should look something like this, with the<br />

pull on the band moving in one direction and the friction or <strong>res</strong>istance from<br />

the test surface (desk) moving in the opposite direction. PC PA<br />

Differentiation<br />

• Less capable students can work together in a small group with teacher assistance to ensure they<br />

are able to measure and record <strong>res</strong>ults correctly on page 123. Students may also provide oral<br />

<strong>res</strong>ponses to the questions on page 124.<br />

• More capable students may test other shoe sole types and consider what kinds of materials, as<br />

well as patterns, are used on the soles of shoes.<br />

• creating a ramp structure<br />

Background information<br />

• Gravity is an invisible force that is applied at a<br />

distance, pulling any two objects together, causing<br />

them to accelerate at 9.8 m/sec 2 . This explains<br />

why the mass of an object doesn’t affect the rate<br />

at which it accelerates towards Earth. However, its<br />

speed can be affected by its surface area because<br />

of increased or decreased air <strong>res</strong>istance.<br />

• The force of attraction between two objects<br />

depends on the size of the objects and the distance<br />

between them. As Earth is by far the biggest object,<br />

gravity is observable when objects are being pulled<br />

down towards its centre, and are seen to be falling.<br />

• Watch this video for more information: .<br />

Assessment focus:<br />

on pages 128–129 as a formative<br />

assessment of students’ understanding<br />

that gravity is an invisible force that<br />

pulls objects to the ground at the<br />

same rate (Object drop and Water<br />

drop), but can be affected by the<br />

height it drops from (Marble drop) and<br />

the speed it travels down a steep ramp<br />

(Rolling on different planes).<br />

Lesson plan<br />

Introduction:<br />

1. Engage students by watching a short animation at , without<br />

explaining it first. It is a re-telling of the story of Isaac Newton’s theory about gravity. With a partner,<br />

students discuss the force that was shown. In which direction was it moving? Was it a direct force?<br />

QP<br />

Development:<br />

2. Introduce the term gravitational force. Students suggest other examples of gravity at work. Watch<br />

the video at and then write a definition for gravity or gravitational force<br />

and add it to a word wall. PC C<br />

3. Students conduct a series of short experiments to understand the effects of gravity on different<br />

objects in different situations. Set up different stations as shown on page 127 and place a copy of<br />

each experiment card, detailing the materials and procedure, at each station for students to fol<strong>low</strong>.<br />

Depending on class size, two of each station may be required. PC<br />

4. Students use pages 128 and 129 to predict and then record <strong>res</strong>ults, as well as using an iPad ® to<br />

record video footage of the experiment <strong>res</strong>ults. PA<br />

The expected <strong>res</strong>ults and explanations of the activities are as fol<strong>low</strong>s:<br />

Rolling on different planes<br />

The ball will roll fastest on the higher, and therefore steepest ramp. This is because the ball<br />

accelerates more on a steeper ramp as it is being pulled towards Earth.<br />

Marble drop<br />

A marble dropped at a shorter height will leave a smaller crater in the flour tray, while a marble<br />

dropped at a greater height will leave a larger crater. This is because the force of the marble<br />

being pulled towards Earth is stronger at a greater distance and therefore has a greater impact.<br />

Water drop<br />

The water will no longer spill out from the hole in the cup when it is dropped. This is because the<br />

gravity is pulling on the water and cup equally so they fall at the same speed and no water spills<br />

out.<br />

Object drop<br />

The two balls of the same size but different weight will hit the ground at the same time. This is<br />

because gravity is pulling them at the same speed and affects the objects the same way, even if<br />

one is heavier.<br />

Differentiation:<br />

• Less capable students can work together with the teacher to guide the experiments and scaffold<br />

their learning and observations.<br />

• More capable students can draw their own table of <strong>res</strong>ults rather than using pages 128 and 129.<br />

Introduction:<br />

1. Recall the experiment from the previous lesson, where two balls of the same size but with different<br />

weights were dropped. What was the <strong>res</strong>ult? What would happen if you dropped a scrunched up<br />

piece of paper and a flat piece of paper at the same time from the same height? What would be<br />

different about this experiment compared to the ball drop? Get a quick show of hands predicting<br />

which paper will hit the ground first and then conduct a simple demonstration. QP<br />

Development:<br />

2. Discuss the <strong>res</strong>ult as a class. Did you predict correctly? Why did the scrunched up paper hit the<br />

ground first? Is gravity the only force affecting the paper? What other kind of force could there be?<br />

PA QP<br />

3. Watch an explanation of the experiment at and discuss the term air<br />

<strong>res</strong>istance. In which direction does the force of air <strong>res</strong>istance act on the sheet of paper? What kind of<br />

force do you think air <strong>res</strong>istance is similar to? (Remind students about friction.) What about the force<br />

of gravity? In which direction is the force of gravity moving the piece of paper? Which is a push and<br />

which is a pull? PC C<br />

gravity is the greater force as the paper does<br />

eventually fall to the ground, but if they are<br />

a parachute. Play an introductory video of the experiment at ,<br />

stopping it at 2:15. In small groups, students plan and create a design to test, using page 132.<br />

Remind students that the objective is to make the pushing force of air <strong>res</strong>istance strong enough to<br />

s<strong>low</strong> down the pulling force of gravity. Students record their egg drop using a digital camera or an<br />

Egg drop experiment<br />

Hypothesis:<br />

The parachute will work best if the surface area is large small because the<br />

pushing force of air <strong>res</strong>istance will s<strong>low</strong> down speed up the pulling force of<br />

gravity.<br />

Materials and procedure:<br />

1. Design a parachute to test out, using a square or rectangular piece of<br />

plastic.<br />

2. Use an iPad ® to draw and label your design.<br />

3. Calculate the area of the plastic being used in the parachute and write it<br />

on the plastic with a permanent marker.<br />

4. The eggs will be placed in a small plastic cup with the parachute<br />

attached to it, similar to the video just viewed.<br />

5. Consider what you learnt about surface area affecting air <strong>res</strong>istance.<br />

6. If your first design doesn’t work, then refine the area and cut a new piece<br />

of plastic to try again.<br />

Observations and <strong>res</strong>ults:<br />

Drop the egg parachutes one at a time from the same height by standing<br />

safely on a chair or bench.<br />

Record the <strong>res</strong>ults using a video application on an iPad ® .<br />

Conclusion:<br />

The parachute worked best when it had a<br />

larger smaller surface area.<br />

Background information<br />

• A magnet exerts an invisible force which can either<br />

make an object move away from or towards it. If contact<br />

between two magnets is established, it is maintained<br />

by the magnetic field. Attaching a metal object to a<br />

magnet enables the metal object to act as a magnet.<br />

• When the same poles on two magnets are held close<br />

together the magnets will repel each other. When<br />

different poles of two magnets are held close together,<br />

the magnets will attract each other.<br />

• Magnetic materials include iron, nickel, cobalt and steel.<br />

Metals which repel magnets include brass, zinc, copper<br />

and aluminium.<br />

FORCES NEAR AND FAR<br />

Lesson plan<br />

Introduction:<br />

1. Set up a simple magic trick to show the students, which involves a magnet underneath a piece<br />

of card and a metal object like a paperclip on top. Ask students if they think you can move the<br />

paperclip from one side of the cardboard to the other, without touching it or b<strong>low</strong>ing on it. Without<br />

showing the magnet, move it s<strong>low</strong>ly underneath the cardboard and drag the paperclip to the other<br />

side of the card. Students hypothesise how you did it, and make a class list of ideas. QP<br />

Development:<br />

2. Show students the magnet and al<strong>low</strong> small groups to explore magnets and various metal objects<br />

in order to familiarise themselves with how it works, and what kinds of metal they are attracted to<br />

(anything made from iron, nickel, steel, other magnets) and not attracted to (anything made from<br />

copper, gold, aluminium, zinc or brass). PC<br />

3. Students then move around different stations placed around the classroom, to conduct magnetic<br />

challenges as shown on pages 135 and 136. Place a copy of the materials and procedure at each<br />

station. Students will need to bring either a science journal, a piece of paper or an iPad ® to draw<br />

tables where appropriate and record their <strong>res</strong>ults, or answer the questions listed. PC<br />

Note: See this video for a more complicated version of the Magnetic field experiment, should you<br />

require further explanation .<br />

The Levitator experiment works by using like poles to repel the pencil and make it appear to<br />

levitate.<br />

The Pipe time experiment is based on the repelling force of the magnet and aluminium/copper,<br />

which causes the magnet to s<strong>low</strong> down when passed through an aluminium or copper pipe.<br />

Students may wish to repeat this experiment and watch the magnet as it travels through the<br />

repelling pipe.<br />

Differentiation<br />

• Less capable students should have more free practice playing and experimenting if they do not<br />

grasp the concept of magnets acting as a force.<br />

• More capable students can test their knowledge of magnetic force by completing the quiz at<br />

on an iPad ® .<br />

Reflection:<br />

4. As a class, watch the video about magnets and magnetic fields at .<br />

Discuss what the <strong>res</strong>ults from the magnetic field experiment showed. (Even though the magnet is<br />

not in direct contact it still attracts the paperclip. The distance at which the paperclip is no longer<br />

directly attached to the magnet but is still attracted to it shows the magnetic field.) Discuss the Pipe<br />

time <strong>res</strong>ults and why they occurred. PA E<br />

5. In their science journals, or using an iPad ® students answer the fol<strong>low</strong>ing questions: Which<br />

experiments used magnetic attraction as a force? Which experiments used magnetic repelling as a<br />

force? Do magnets need to be in direct contact with an object for it to work? C<br />

• Students describe how static is part of our everyday<br />

lives.<br />

Technology/Engineering/Mathematics links:<br />

• exploring how static forces and materials that can<br />

be charged, can be used to move an object<br />

Background information<br />

• Static works as a force to move objects from a<br />

distance when an object is charged and either<br />

attracts or repels another object. Two positively<br />

charged objects will repel each other, as will two<br />

negatively charged objects, while a positively<br />

charged and a negatively object are attracted to<br />

each other.<br />

• A charge occurs when materials that are good<br />

electrical insulators are rubbed together, such as<br />

a cloth and a PVC pipe. The charge from the cloth<br />

is transferred to the pipe. The pipe can then attract<br />

uncharged objects or repel other charged objects.<br />

• The charge does not last forever, so objects that<br />

were once attracted or repelled will not always be.<br />

• Even though static causes attraction and repulsion,<br />

it is not the same as a magnetic force.<br />

• Further detailed information about static can be<br />

found at .<br />

• A series of static experiments similar to those on<br />

page 141 can be viewed at .<br />

Assessment focus:<br />

• Use the <strong>res</strong>ponses for pages 140–141<br />

as a formative assessment of the<br />

student’s ability to make a prediction<br />

and observe <strong>res</strong>ults, and record<br />

the information in a table. Use their<br />

answers to ascertain whether they<br />

understand the concept that static is<br />

a force that can repel or attract from<br />

a distance. It is not necessary at this<br />

Lesson plan<br />

Introduction:<br />

1. Hold a balloon at the front of the class. What will happen if I rub this balloon on my hair and then<br />

move the balloon away s<strong>low</strong>ly? Is this a force? What kind of force? Does it need to be in direct<br />

contact for it to move my hair? QP<br />

2. Al<strong>low</strong> students a few minutes to try it out with a partner, and see how far away the balloon can be<br />

so that it still moves the hair. PC<br />

Development:<br />

3. Introduce the term static electricity. Ask students<br />

to recall any other times that they may have<br />

experienced static. Have you ever taken the<br />

plastic wrapping off something and had it stick<br />

to your hand? QP C<br />

4. Students explore other examples of static<br />

electricity and how it acts as a type of force.<br />

Small groups rotate around six stations, labelled<br />

with the experiment cards from page 139. Each<br />

station explo<strong>res</strong> how static can move objects,<br />

either by repelling or attracting them. Al<strong>low</strong> five<br />

minutes for each station and set a timer for each<br />

round. Students use pages 140–141 to record<br />

predictions and observations. The teacher<br />

should set up Station 3. Note: A 40-cm plastic<br />

ruler is suggested as a shorter ruler is too close<br />

to the hand, which attracts charged objects and<br />

will affect the experiment <strong>res</strong>ults. QP PC PA<br />

Differentiation<br />

• Less capable students can use diagrams<br />

instead to draw their predictions and to<br />

explain their observations.<br />

• More capable students can attempt<br />

to explain the reasons behind their<br />

observations if they understand the concept<br />

of charged objects.<br />

Reflection:<br />

Each station should yield these suggested<br />

<strong>res</strong>ults:<br />

Station 1– Move the can: The charged pipe/ruler<br />

should attract the can and pull it towards the pipe/<br />

ruler. The wooden ruler will not do anything as<br />

wood is not a good electrical insulator.<br />

Station 2 – Move the plastic: The charged balloon<br />

and the charged plastic will repel each other and<br />

the plastic strip should appear to levitate. The<br />

wooden ruler will not repel the plastic bag.<br />

Station 3 – Move the balloons: The charged pipe/<br />

ruler will repel the balloons as it is moved vertically<br />

between them. Once the balloons are also rubbed<br />

with the cloth, they will then repel each other and<br />

not hang in a straight line. A hand placed near<br />

the charged balloons will attract them. After a few<br />

hours the balloons will lose their charge.<br />

Station 4 – Move the bubbles: The charged pipe/<br />

ruler will attract the bubbles.<br />

Station 5 – Move the water: The charged pipe/<br />

ruler will cause the water to appear to bend as it is<br />

attracted to the pipe/ruler.<br />

Station 6 – Move the polystyrene: The charged cups<br />

or plates will repel each other and students will not<br />

be able to place them on top of each other. Using<br />

the magnet will show that static is not a magnetic<br />

force and has no effect on the movement of the<br />

charged polystyrene items.<br />

5. As a class, discuss each station, including which material was better at creating static force—wood<br />

or plastic. Is static a contact force or a distant force? What kinds of materials were affected by static?<br />

Read a list of common materials at , and scroll down to read the Easy<br />

reading explanation. E C<br />

6. As a class, create a Venn diagram for magnetic and static electricity forces. Is static the same as a<br />

magnetic force? How do you know? How are magnetic forces similar to static? How are magnetic<br />

forces different to static? C PA<br />

<strong>STEM</strong> project overview<br />

Students use their knowledge of contact and non-contact forces to design a UFO that hovers and<br />

moves a length of one metre across a hover base.<br />

Concepts overview:<br />

<strong>Science</strong><br />

• Apply knowledge of forces exerted by one object on another, either directly or indirectly.<br />

• Conduct an investigation into how to make a UFO appear to hover, with the use of the repelling<br />

force of magnets.<br />

• Communicate findings by sharing the video of the UFO in action.<br />

Technology/engineering<br />

• Plan steps collaboratively.<br />

• Design and create a UFO, hover base and skyscape using a variety of materials.<br />

• Investigate how forces and the properties of materials affect the behaviour of the UFO and hover<br />

base.<br />

• Evaluate and revise the UFO, hover base and skyscape.<br />

• P<strong>res</strong>ent information using a digital application to record a video and add sound effects.<br />

• Upload a video to a computer or website.<br />

Mathematics<br />

• Use measurements to create a hover base that is 1 m in length.<br />

• Use measurements to create a UFO that will fit inside the hover base.<br />

Alternative project ideas:<br />

• Use a series of tricks based on the non-contact forces of magnets and static electricity to create a<br />

magic show. Students create props and outfits and record a video of the magic performance.<br />

• Students are faced with a problem of how to move a large piano from one end of a room to the<br />

other. The floor has carpet and the piano weighs 400 kg! Design a device or product that can<br />

assist the students to move the piano more easily.<br />

<strong>STEM</strong> project:<br />

Teacher notes<br />

Students use their knowledge of contact and non-contact forces to design a UFO that hovers and<br />

moves a length of one metre across a hover base.<br />

Estimated duration: 4 weeks<br />

1. Introduce the project<br />

• Watch an old movie scene showing the<br />

special effects used for a UFO travelling<br />

across a skyscape at . Discuss or demonstrate how<br />

they used to make these scenes using a<br />

model UFO dangling on a piece of string.<br />

• Display page 148 and read through the<br />

project, clarifying any details the students<br />

are unsure of.<br />

2. Investigate<br />

• Students revise contact forces (pushes and<br />

pulls that require direct contact, such as<br />

friction or air <strong>res</strong>istance) and non-contact<br />

forces (magnets, gravity and static). From<br />

there they should be able to determine that<br />

magnets can be used to make something<br />

appear to levitate. Students may wish to<br />

explore videos of levitating objects with<br />

magnets.<br />

• In order to be able to scaffold students’<br />

learning, watch the clip at , which demonstrates<br />

exactly how to make a hovering UFO. It will<br />

give teachers the knowledge to be able to<br />

help students with their designs, without<br />

giving away too much to the students if<br />

they were to watch the video themselves.<br />

The video is a <strong>res</strong>ource on Scootle so a<br />

Government school login is required.<br />

• Students <strong>res</strong>earch different skyscapes and<br />

UFO designs on which to base their own.<br />

They will need to consider which materials<br />

are suitable, especially to keep the weight<br />

of the UFO to a minimum in order for<br />

the repelling magnet force to be able to<br />

support it.<br />

3. Design, plan and manage<br />

• Students draw diagrams of their UFO<br />

design, the hover base (which must be<br />

1 m long and contained within a cardboard<br />

box), and sketch a plan of their skyscape.<br />

They then label the materials they plan on<br />

using to make their items.<br />

• For smooth running of the project, students<br />

should allocate roles to team members.<br />

4. Create<br />

• Students create their UFO, hover base and<br />

skyscape based on their plans.<br />

5. Evaluate and refine<br />

• Students test their UFO and hover base<br />

and see if the repelling magnets keep the<br />

UFO up. Otherwise they may need to revise<br />

the UFO or hover base design.<br />

• Students should ensure they have<br />

considered all of the criteria listed on<br />

page 148.<br />

6. Communicate<br />

• Students film a short video of the UFO in<br />

action, moving left or right across the hover<br />

base with the skyscape in the background.<br />

• The footage can then be edited using<br />

an application like iMovie ® to add sound<br />

effects.<br />

• Students share the video with the class or<br />

upload it to a school website.<br />

The problem<br />

Project brief<br />

ALIEN FORCES<br />

Movie special effects have come a long way since black and white movies!<br />

UFOs no longer need to be dangled from a wire and moved across a camera.<br />

How can you use what you have learnt about invisible forces and contact forces<br />

to make a short video of a UFO?<br />

The task<br />

• You need to create a scene for a movie that shows a UFO moving across a<br />

skyscape. You will need to make a UFO, and a hover base for the UFO to<br />

move across. You will also design and create a skyscape background to add<br />

to the hover base. You will then need to film the moving UFO and create a<br />

short movie scene.<br />

Things to consider<br />

• You must work in groups of 2–3 students.<br />

• You must make a simple UFO with a weight that can be supported by a noncontact<br />

force.<br />

• The UFO must move left or right across a hover base contained within a<br />

cardboard box.<br />

• The UFO must travel a distance of at least one metre so your hover base<br />

should be at least that long.<br />

• You need to create a skyscape prop to add along one side of the hover base.<br />

• You need to film a video of the UFO flying across the skyscape and add<br />

some sound effects.<br />

• The video should be approximately one minute.<br />
