About This Lesson
In this lesson, students explore the water cycle and the role it can play in making water drinkable. Through an online video, Peace Corps Volunteers Nicholas Hanson and Brian Newhouse describe how they built a solar still to distill saltwater into drinkable water in Cape Verde. During the first class period, students construct their own model solar stills. In the second class period, they check to see how much pure water their solar stills produced from a supply of saltwater.
