Food stores energy and is the fuel that keeps your body moving. Calories — yes, the same calories that people talk about when they are trying to lose weight — are one way to figure out how much energy food contains. More calories means there is more energy. This video shows you another way that scientists can figure out how much energy is in a particular food -- by setting the food on fire! (3:15)

An Italian restaurant owner built a people-powered amusement park. It only contains rides that are powered by people. To ride these rides, people have to put energy in by pedaling, pushing, or climbing. Take a quick tour and watch people use their own energy to make a loop-de-loop! (1:38)

THIS LESSON WAS REVISED ON APRIL 27, 2019. Here is a link to the previous version.
In this Mystery, 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.

Prep Instructions

We recommend students work in pairs. Homeschool students can work on their own, but they will need to make two models so that they can compare and contrast what happens when using the thin versus thick rubber band.

Prepare the Classroom Space

Student pairs will need to set up two Twist-O-Matic models next to each other for easier comparison between the thin and thick rubber bands. Each model takes up the space of about one student desk, so it is easiest if student pairs are sitting next to one another.
