Lead class to a discussion about the different types of renewable energy. Show students some youtube movies about wind power. Lead students into an investigation about designing and constructing their own wind turbine. Use the PROE worksheet to plan their investigation. The challenge is to make a wind turbine lift a plastic cup to bench height. The students place counters one at a time for each trial and see how high they can lift their cup using the power from their wind turbine. Students record their findings on the table and use data to create a line graph to show pattens in their results. To conclude students evaluate and explain their findings. There is a rubric to accompany this. Should you require the rubric - contact the seller.
