Our project will demonstrate the law of conservation of energy by the marble being on top of the hill making it potential energy and when the marble rolls down it will be kinetic energy since it’s in motion. The energy of the ball rolling down the ramp is gravitational energy. How we would show chemical energy you ask, well we will show chemical energy by having the marble hit another marble showing their has been a change in the color making it a chemical change. Thermal energy is already shown because since the ball is moving it has friction and friction cause heat. We will show elastic energy by using a fly swatter or the ramp and it will bend down and make the ball shoot up and bounce and once that happen it will hit Luke’s computer and
