Solar Power to the Rescue!
Students learn how the innovative engineering of photovoltaics enables us to transform the sun’s energy into usable power—electricity—through the use of photovoltaic cells. Watching a short video clip from “The Martian” movie shows the importance of photovoltaics in powering space exploration at extreme distances from the Earth. Then students learn that the photovoltaic technologies designed to excel in the harsh environment of space have the potential to be just as beneficial on Earth—providing electricity-generating systems based on renewable energy sources is important for our electricity-gobbling society. Two student journaling sheets assist with vocabulary and concepts.
