Design and build a vehicle that is propelled by the energy stored in rubber bands. Make it go for a distance, stop with precision, cross a difficult terrain, or speed down a track. Rubber band racers can be easily reengineered, so every day you can have a different challenge.
Learn engineering and scientific concepts including potential and kinetic energy, friction, and simple machines.
Optional: Start your rubber band racer as a ramp-roll vehicle. See how mass, height, friction, and other variables affect how far it travels. Use this understanding to help you create your rubber band-powered racer.
