In order to reach safety, you have to get back to base camp which lies East.
In your kit you only have these materials:
- A bowl of water
- A sewing needle or paperclip
- A magnet
Can you engineer a way to find your base camp through the dense Amazon jungle?
The aim is to try make a working compass from materials that you can find at home. The tricky part of this project is to work out how to make a needle float on water. You will learn about magnetism, navigation, magnetic poles, physics and forces.
WHAT YOU'LL NEED
A bowl (non-metallic) of water, a steel needle or paperclip, a tissue paper and a flat fridge magnet (rare earth magnets or straight bar magnets work best)
QUESTIONS TO THINK ABOUT
How and why the needle acts as a compass? Why does the needle get magnetised?
What went well? What didn’t go so well? What would you do differently next time?
