Roller Coasters

Twisting and turning through the sky, roller coasters are popular attractions at amusement parks around the world, but how exactly do they work? Explore the physics behind these thrilling rides with an engineering design activity. Starting with a discussion of potential and kinetic energy and the law of conservation of energy, young engineers apply these concepts as they work in groups creating roller coasters using flexible plastic tubing and marbles. Learners will likely be very energetic during this activity, so be sure to provide clear expectations for their behavior to ensure everyone's safety. Present this lesson as an introduction to a science unit on energy and engage the class in learning about this fundamental topic.
