**WINDMILLS**
Kaitlyn w 2011-2013

**ABSTRACT **
 The purpose of this study was to determine which shape, material, and size blade will generate the most electricity. Windmills use the sail to develop power; the classic windmill has four big vertical sails. In the first experiment right side up triangle Styrofoam blades where taped to the propeller. The Styrofoam blades generated the most electricity with 1.48 (V) and the plastic cups made the least amount of e lectricity with 0.43 (V). It was determined that diamond, Styrofoam medium blades generated the most electricity.

**EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS**
====I think a cool experiment that could be done in the future would be to see if the wind mill generates more electricity in the light or in the dark. Also real windmills are high up so it would be interesting to see if the windmill being higher affects the amount of electricity generated. If I where to do this project again I would test more materials, designs, and sizes. To see even more results and to see what blades are the best and what blades do not work well.====
