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

In this activity, learners build a switch to turn electrical circuits on and off.

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

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

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.

This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.

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

In this activity, learners construct cars that are powered by hand-made, electric propellers.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.
