Hill Quest

Wheels, axles, chassis parts, connectors and rubber bands are the basic components of each kit that allows students to construct cars that sprint or creep to the top of a wooden ramp…jousting with another student’s car. Challenge: Beat your opponent to the top of the three foot ramp and hold your ground. The project tests all the dynamics of Force and Motion and tests planning and problem solving.

When you build a catapult with three simple machines as part of the design (lever, pulley, screw), you add multiple levels of complexity to an already elegantly conceived machine. Adjust trajectory, control trigger mechanism and launch ping pong balls with more thoughtful plans than just point and release.
