Using visual youtube tutorials we learnt how to make catapults. Working together in small groups we followed the directions and then tested our creations. As we were testing our designs, we noticed that the rubber band would stretch when we pressed on it. This gave the spoon potential energy. When we let go, the scrunched up paper would fly through the air. This happened because we had released the potential energy and it changed to kinetic energy.
