In Earth and Environmental Sciences, we learn about renewable and nonrenewable energy, including solar. With this hands-on activity, you can introduce students to the real-world application of solar energy through the use of photovoltaic (PV) cells. In this lab, students work with mini solar panels, motors, and other simple components to build a working solar-powered device. As they watch their motor spin using only the power of sunlight, students get an immediate and visual understanding of ho
