Rubberband rocket

Purpose: We were learning about potential energy and kinetic energy we were in groups yr 3 boys yr 3 girls yr 4 boys and yr 4 girls.

Materials: Plane, Handel, rubber band

Method:1. First we figured out how to use the matrerials. first we put the rubber band on the handle then we each had 1 turn.

Observations:my turn was very bad when I flung it it went beside the tree.

Conclusion: from this experiment where this energy is coming from. It is first potential energy it's power comes from us pulling the rubber band. When we let go it turns into kinetic energy because it was going into the rocket. When we fling it the power is on the rocket to fly.
