Catapult - Potential Energy

Build your own catapult and experiment with physics in this STEAM kit.  This catapult is made up of a rubber band, fulcrum and a lever.  The sides of the catapult are built using triangles to make the structure strong.  This catapult stores energy in a rubber band. The pull you feel from the rubber band is called potential energy. The more energy you pack in, the higher your ball will go.  When you launch an object with a catapult, the object follows a path through the air. The path is called a trajectory.

 

Grade 2-6

 

Activity Ideas:

Challenge friends to see who can make their pom pom travel the furthest.  Another option, add a target to a wall with different score zones,  see who can score the highest combined total with 3 tries.
