Marble Maze

My students are learning about energy. They made marble mazes in the gym. They had masking tape and paper towel rolls. There challenge was to make the marble land in the cup. They were so excited to do this project. They worked well in their groups and cam up with some great ideas. They really had to take into consideration potential and kinetic energy. A question we talk about is why does a roller coaster have its first drop from the highest point? It stores up its energy. They had to have their marble have enough energy to make it down the run. Would it have enough energy to go up an incline??
