THIS LESSON WAS REVISED ON APRIL 27, 2019. Here is a link to the previous version.
In this lesson, students learn that we use the energy from food to make our bodies move just like cars use the energy from gasoline to move. In the activity, Twist-o-matic Tester, students build paper models of an amusement park ride called the Twist-o-Matic. The ride stores energy in rubber bands and spins around when the energy is released. Students compare the speed of the spins when they use a thin rubber band versus a thick rubber band.
