The 5th grade STRETCH class had their first experiment exploring wind power and building the most effective windmills. We tested 3 types of material: construction paper, printer paper, and card-stock paper. Each team built 3 types of windmill and tested them. We concluded that card-stock definitely made the strongest sail. We will be applying this theory in the next segment of water wheels.
