Levers of Destruction! Trebuchets, Catapults and Jaws!

This "lesson" was specifically targeting the Nova Engineering Module. As an engineer, I'm a little disappointed they focused solely on levers, so I tried to make it as interesting as possible.  When you're dealing with kids age 6-11, destruction makes things interesting!  We were able to review the three types of lever, while having a snack and shooting paper balls and ping pong balls.
