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?
the two tone red and blue windmill we made in second lesson:

maximum current value: 4.2, 7.5, 8.6 then 9 mA on highest wind setting

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?

Hi Nice BLog Did you know that your laptop will recharge the laptop battery hpmuch faster if you power the laptop off? A typical laptop will recharge the battery in about 3 hours when it is turned on, but when turned off, that same battery will recharge in about half the time.
