Balloon Car | STEM Lesson Plan

Here's a challenge: turn a pile of recycled and craft materials into a toy car. Then, add something to the car so it can zip along under its own power. You can do this using a balloon. When you inflate a balloon, it stores potential energy. When you release the balloon, this energy is converted to kinetic energy, the energy of motion. Attaching the balloon to a straw allows you to direct the escaping air to propel your car forward. Try competing with your classmates to build different designs an

d see whose car will go the farthest. To view written instructions for this lesson plan, click the link at the end of this video.
