Fire safety
- A glass jar over a burning candle: the flame goes out, because the oxygen is used up.
- A pot of oil catches fire: an adult turns off the stove and covers the pot.
- Never leave a pot on the stove unattended.
Energy in springs and elastic bands
| Toy | Where is the energy stored? |
|---|---|
| Wind-up toy car | In the wound-up spring |
| Jack-in-the-box | In the squashed spring |
| Pogo stick | In the spring that squashes and springs back |
| Trampoline | In the stretched springs |
| Rubber-band rocket | In the stretched elastic band |
Twist a toy car’s elastic band more times and the car goes further: more stored energy.
A fair test
Sizwe tests whether stretching an elastic band further makes a paper ball fly further. He changes only how far he stretches the band, keeps the same band and ball, and measures how far the ball flies. He does each test three times so his results are reliable.
Good prediction: “If I stretch the band further, the ball will fly further.”
A peanut’s energy first comes from the Sun. In class, a teacher can burn one under a test tube of water to show how much heat energy it stores. Never try this at home.
Remember this and test yourself
- A fire needs fuel, heat and oxygen; a flammable substance burns easily.
- During a fire drill you walk calmly to the meeting point; in smoke you crawl low.
- A damaged power cord: leave it and tell an adult. Do not plug too many appliances into one socket.
- A stretched or twisted elastic band and a squashed spring hold stored energy.
- Let go: the stored energy becomes movement energy (kinetic).
Write these points in your book. Read them again the night before the test.
Fire’s three friends: Fuel, Heat, Oxygen. Take one away and the party is over.
