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

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 explore how watermills have helped harness energy from water through the ages.

In this activity, learners discover how solar energy can be used to heat water.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
