15. The science of it all... Experiment Control variables Independent variable Dependent variable Design contest Challengers try to optimize all variables (within certain parameters) to achieve the best results for the target quantity

16. The Challenge Within the remaining time, you and your group are to design a set of blades to complete a wind turbine to harness the most amount of wind energy.

17. Materials Masking tape Wooden dowels Cardboard

18. Parameters Only use the permitted materials Everyone uses the same wind source The wind source will be a fixed distance away You must use the dowels to attach your blades to the rotor You can have 1 – 12 blades

19. Testing your results Once you attach your blades to complete the turbine, your output voltage will be measured using a multimeter. Your goal is to have the highest reading.
