Our Re-Energy Challenge is a fun and engaging science activity where learners have the opportunity to build a working model of a solar oven, a solar car, a wind turbine, a hydroelectric generator, a biogas generator, an electric vehicle or an energy storage system—so they can see firsthand how applied science is helping create a more sustainable future. Suitable for grades 3-12.
