So for my Physics and Engineering portion we had to make a wind turbine that can spin and conduct electricity. For the turbine we made the blades out of plastic but it was to flat so it wouldn't spin. So then we made blades out of foam Popsicle sticks and thumb tacks it worked but it would hit the base and it eventually stopped working. So our final bade was only made out of paper but it was curved so it was able to spin by the fan pretty fast. We eventually had data and had to make a presentation. The presentation had all of our blades revisions data and all of that.
