Introduction - 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?
With our pink redesign of turbine, current is 2.6, then 6.6 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?
