For our second science club meeting we taught the students about a form of alterative energy. We had the students creat a windmill. They had to go thru a trial and error process in getting the blades on the windmill to work properly. They had to decide as a group how many blades, the angle of the blades, and the design of the blades, etc. There was a lot of wind outside that day so the students had perfect condidtions to get their windmills to work properly. Through this process the students learned the most effective windmill model. The goal of the blade design is to reduce resistance and increase lift.
They learned that the generator inside of a wind turbine converts mechanical energy into electrical energy.
