MATERIALS: • various packaging for foods collected from home INSTRUCTIONS: 1. Work in pairs. 2. There is a collection of packages from dierent types of foods in your classroom. 3. Look carefully at the energy information given on the packets and use this information to complete the table. 4. It is important to record the number and the unit in your table. Food item Energy per 100g QUESTIONS: 1. Which food item contains the most amount of energy per 100g? 2. Which food item contains the least amount of energy per 100g? 10 Energy and Change
Some fuels are energy sources for engines and power stations Fuels can also be used to give us other forms of useful energy. Petrol or diesel is used in cars and trucks to make them go. The stored energy in the fuel is changed into movement energy of the car or truck. Putting petrol into a car at a petrol station. Petrol and diesel are made from fossil fuels. Can you see that even energy for cars and generating electricity comes from the Sun? Energy from the Sun is stored in the plants and animals which eat the plants. Their remains turned into fossil fuels over millions of years which are then mined and used to make petrol and diesel to fuel cars. Chapter 1.
