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

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.

Materials

• Masking tape• Wooden dowels• Cardboard

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

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.
