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.
