Chapter 17: Invertebrate Animals

Start-Up Activities
How are animals organized
Scientists have identified at least 1.5 million
different kinds of animals. In the following
lab, you will learn about organizing animals
by building a bulletin board display.
STEP 1
Invertebrates Make the following
Foldable to compare and
contrast the characteristics of
water and land invertebrates.
Fold one sheet of paper lengthwise.
1. Write the names of different groups of
animals on large envelopes and attach
them to a bulletin board.
2. Choose an animal group to study. Make
an information card about each animal
with its picture on one side and characteristics
on the other side.
3. Place your finished cards inside the
appropriate envelope.
4. Select an envelope from the bulletin
board for a different group of animals.
Using the information on the cards, sort
the animals into groups.
5. Think Critically What common characteristics
do these animals have What
characteristics did you use to classify them
into smaller groups Record your answers
in your Science Journal.

Fold into thirds.
Unfold and draw overlapping ovals.
Cut the top sheet along the folds.
Label the ovals as shown.

Construct a Venn Diagram As you read this
chapter, list the characteristics unique to water
invertebrates under the left tab, those unique
to land invertebrates under the right tab, and
those characteristics common to both under the
middle tab.
