A wind turbine is essentially just a giant pinwheel, right? Individuals first create pinwheels from paper, pins, and pencils. In groups, they model a wind farm along a coast and then test out their designs using an electric fan.

In this science fair project, you will learn more about wind-powered devices, like pinwheels. Much like pinwheels, we react in different ways to the direction of the wind when we ride bikes, or even try to walk.

So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this...

Students learn about wind energy by making a pinwheel to model a wind turbine. Just like engineers, they decide where and how their turbine works best by testing it in different areas of the playground.
