- what were you investigating?

Prediction - will your design produce enough energy to charge an iPod for an hour in the 10 minutes you have?

Conclusion - What did you discover?

red and white design didn't move,
red and yellow design: 8.4 mA 10mA 11.1 mA

Evaluation - How would you improve your windmill design if you were doing this experiment again?

What would you like to ask a power expert about this experiment?
