This Roller Ball lesson plan also includes:
Watch your class reach its potential (energy) with this activity. In groups of three, elementary school scientists place a golf ball on a ramp: 5cm from the bottom, then 10 cm, and then 15 cm. They let it roll and measure the distance beyond the ramp where it came to rest. Discuss as a class or have older children write answers to the questions listed on the lab sheet. This classic lesson on kinetic and potential energy is even more easily taught using this guide.
