Review Unit 10

Our bodies need a supply of energy to be active. How do we get our supply of energy? Choose from:

• from our food

• by drinking water

• by wearing warm clothes

• directly from sunlight

Fuels are used stores of energy. How do we get the energy from a fuel? Choose from:

• by moving it

• by storing it

• by burning it

• by eating it

What type of energy store is a fuel? Choose from:
