Students begin by identifying all of the types of energy they used today and classifying this energy as potential or kinetic. Then, students break down the energy changes that occur in a bouncing ball and collect data about how drop height affects bounce height. Students create an excellent graph of their data with TAILS (Title, Axes, Intervals, Labels, Scale) and use their graph to answer the question How does gravitational potential energy affect the total energy in the bouncing ball system? Finally, students use pendulums to figure out how the total amount of potential energy in a system changes!
