Sixth graders completed a new project recently. They were tasked with designing the most efficient wind turbine they could using sheets of aluminum flashing. Students studied the many varied styles of wind turbines and how they functioned. The class settled on building horizontally mounted turbines. We then dove into how the number of blades and the weight of the blades can have big implications into how well the turbine will run. Using some 900 RPM gear motors we were able to mount these blades and begin blowing the air compressor onto them to see how much power we could draw off of them. Students typically had to go back to the drawing board a few times before they discovered a solution for the dividing and folding of the blades. This project was really amazing to complete as the students could watch the output on the multimeter and see the differences each version made.
