Solar Fountains

This activity demonstrates how solar energy is transformed into electricity that we can use. Students will use solar panels to power a small water pump and build a functioning fountain. In doing so, they will learn how a solar panel works, collect data and test variables, and apply their observations to their engineering process as they improve their designs.
