⚙️ E2 Turning Things

The Prototype Workshop clock tower has stopped. Inside are gears everywhere. Can you work out how gears talk to each other?

Explorers, Foundation. Engineer Stamp: Gear Gremlin.

Lessons

1. Gear friends: If I turn this gear to the right, which way will its friend turn? Point your finger!
2. Whisk it! The egg beater: How does a kitchen whisk spin so fast when your hand turns so slowly?
3. The gear parade: What happens if we put 3 gears in a line? Or 4? Or 5?
4. The propeller pusher: Push the car and a propeller spins! Where does the spin come from?
5. Design Day: The backwards spinner: The clock tower’s hands are going the wrong way round. We need a backwards machine!
6. Showcase: Spinner Parade: Line up the spinners and turn them all at once. Ready, set, spin!

Design challenge

Build a spinner where the handle turns one way and a flag turns the OTHER way.
