In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners explore how watermills have helped harness energy from water through the ages.

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

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.
