In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.
