Simple Machine -- Vibrant Clubs

A catapult is a simple machine that changes the direction or magnitude of a force. This mechanical device is used to launch an object a long distance. The catapult you build will utilize rubber bands. When you pull down on the lever arm, potential energy gets stored up.

Using this vibrant club activity, lead your club through designing and creating a catapult, then investigate how the mechanical device functions through trial and error testing.
