The windmill
Explorers (Foundation), mission E6 Wind & Spin, lesson 2 of 6.
Hook
Long ago, windmills ground flour for bread. How does wind turn a whole tower?
Fair test
Use a fan on low, then high. Watch the top gear. Does it speed up?
Bonus challenge
Tie a paper “flour sack” on a string. Can your windmill wind it up?
