This activity does not require supplies.
In this activity, students solve a mystery: Why do marshmallows and chocolate melt in one car, but not in another car parked nearby? Be prepared to help your students think and talk about what they notice in the video.
In a series of steps, students consider the problem and think about experiments that will help them solve the mystery. After watching the results of some experiments, students realize that the heat of the Sun melted the marshmallows. (If you want to keep your car cool, park in the shade!)
