produces movement
produces growth
powers technology
Gr 5 Natural Sciences and Technology – Term 3, Topic 1

4. Heat energy The sun gives off heat energy.
When something gets hot it gives off heat energy. e.g. solar panels.
Gr 5 Natural Sciences and Technology – Term 3, Topic 1

5. Light energy
This is the type of energy that something gives off when it glows or burns. e.g. torch.
Light travels faster than sound.

6. Energy that enables you to hear something
Sound energy
Energy that enables you to hear something
Gr 5 Natural Sciences and Technology – Term 3, Topic 1

7. Electrical energy
This type of energy is made by an electric current, for example, electrical heaters, stoves and hair dryers.
Gr 5 Natural Sciences and Technology – Term 3, Topic 1

8. Kinetic or movement energy
This is the energy that something has when it is moving, for example, kicking a ball, riding a bicycle.
Gr 5 Natural Sciences and Technology – Term 3, Topic 1

9. Potential or stored energy
Energy that is stored in something. It is waiting to be used.
Gr 5 Natural Sciences and Technology – Term 3, Topic 1

10. Chemical energy
Energy stored in fuels like coal and oil and in batteries and food.
Chemical energy can also be called food energy or stored energy.
Gr 5 Natural Sciences and Technology – Term 3, Topic 1

11. Gravitational potential energy
Gravitational potential energy is the energy of something that could fall due to gravity.
Gravity is the pull of the Earth, for example, a book on the edge of a table has the potential to fall to the ground if it is knocked.
