Simple Machines Made Fun
Can a student really lift their teacher using a lever? How were levers used in medieval warfare? How can you control force using gears and pulleys? Using a twelve foot long lever, three foot tall gears and pulleys, a catapult, and a hand crank music machine, we demonstrate how all simple machines help us do work by trading distance for effort. This is a whole new way to get students excited about simple machines. A great follow up is the Gearing Up for Speed hands on classroom workshop.
