Potential Energy

* Purpose: we were trying to see we're potential Energy comes from when we release the rocket. Materials: we needed a rocket and a rubber band and we needed a handle. Method: we needed to hook the rocket to the rubber band and then we plold the handle back. Observations: when i release my rooket it went high. Conclusion. i learnt that the potential energy comes from my hand and is stored in the rubber band. When i release the band the rocket goes flying up into the air, the energy in the rubber band flys into the rocket and it becomes kinetic energy so it can fly.
