🌬️ E6 Wind & Spin

Prototype Workshop’s electricity has gone out, but it is a very windy day. Can we catch the wind and make it work for us?

Explorers, Foundation. Engineer Stamp: Wind Whisperer.

Lessons

1. Pinwheel spinner: You can’t see the wind, but you can see what it does! Blow and watch.
2. The windmill: Long ago, windmills ground flour for bread. How does wind turn a whole tower?
3. Best blades: Big sails or small sails? Two blades or four? Let’s find the best!
4. The sail car: Boats use wind… could a car sail across the floor?
5. Design Day: Wind racer: The wind is our only fuel today. Whose car will catch the most?
6. Showcase: Windy Day Fair: Three races on the wind track. Cheer for every car!

Design challenge

Build a car that travels the farthest using only wind from a fan.
