Energy makes things happen. We need energy to walk, ride a bike, cook food and drive a car.
Energy comes in different kinds: light, heat, movement, sound and electricity are all kinds of energy.
Some energy is stored, waiting to be used. Food has stored energy. So do batteries, and a stretched rubber band.
Things up high have stored energy too. The higher and heavier something is, the more energy it stores. When a bike rolls down a hill, that energy turns into movement.
Experiment: Ball on a ramp: low, middle, high
- Make a ramp with one book under the board. This is the low ramp.
- Let the ball go from the top. Do not push it! Mark with tape where it stops.
- Add more books to make a middle ramp. Let the ball go from the top again and mark where it stops.
- Add more books for a high ramp and try again.
- Which ball went furthest? Why do you think so?
| Ramp | How far did the ball go? (hand spans) |
|---|---|
| Low | |
| Middle | |
| High |
Questions
Draw something that uses energy. What does the energy do?
🍎Does a stretched rubber band have stored energy?
yes / no
Which ball went furthest in our test, the one from the low or the high ramp? Why?
