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.
