students learn the history of the waterwheel and common uses for water turbines today. they explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. they investigate the transformations of energy involved in turning the blades of a hydro-turbine into work, and experiment with how weight affects the rotational rate of the waterwheel. students also
