Who invented it?
The wheel shows inventions and discoveries. Each spin asks who is behind it, with four names to choose from. Press SPIN!:
Most inventions had more than one inventor, or somebody earlier who nearly got there. The names here are the ones a history book gives, and the ones a test will ask for.
