  1. Ecybermission By Payton, Anna, Nikita, and Kira

  2. Lack of green energy. Percent of windmill usage is very low. Critical in the long run; The energy consumption level will get higher and that will just contribute to global warming. Problem

  3. Our Solution • Windmills; Lower the energy consumption rate and help the environment by not depending on fossil fuels • Find an better, more efficient design of windmills; this will increase the rate of windmill use around our community.

  4. Goal of Experiment • To find out which windmill design spin the most in ten seconds. • The faster the blades spin, the more green energy is produced. • So, the windmill with the most spins produces the greatest amount of green energy.

  5. Hypothesis • We think that the design that will generate the most 'green' energy and having a faster spinning time, is the windmill with the blades on a horizontal axis.

  6. Variables • Independent Variable – We, the scientists, will change the different axes of the windmill (either horizontal or vertical). • Dependent Variable - We will record how many time the windmill makes a full spin in ten seconds.

  7. Variables Continued… • Control group- There is no control; we are comparing two different types of windmills against each other • Constants: Home, same fan on same power setting, types of each material used in design comparison (EX: Printer paper of card board)

  8. Materials • Thumbtacks • Straight plastic straws • Pieces of tape • Corks • 12 inch square piece of lightweight cardboard • 14 inch-long piece of coat hanger wire

  9. Materials Continued… • Card stock and construction paper • 4 bottles of glue • 3 pairs of scissors • 4 glue sticks • A fan (to substitute as wind)

  10. Experiment Steps • Got all of our materials onto a table. • Build our windmills. • Set timer to 10 seconds. • Turn fan on the Low setting. • Position vertical windmill in front of fan. • Turn on timer (10 seconds) • Count how many times it spins.

  11. Experiment Continued… • Record the data and do two more trials. • Position horizontal windmill in front of fan. • Reset timer to 10 seconds, and turn it on. • Count how many times it spins. • Record the data and do two more trials.

  12. Experiment Continued… Click on pictures! How to build windmills Results of the Experiment

  13. Conclusion: A windmill with a horizontal axis will spin faster generating more green energy rather than a windmill with a vertical axis.
