Wind Farm

★ Can you describe what’s happening?
★ Can you explain what is happening?
★ How do you know that?
★ Is there anything you don’t know?
★ Why do you think these windmills have been placed here?
★ Do you think there are times when all the windmills rotate? Can you describe the sorts of conditions when this might happen?
★ If you wanted to make all the windmills rotate at the same speed how would you need to position them?
★ Can you make some paper windmills and make this happen? Think about your source of wind, and where you would position your paper windmills in terms of distance from the wind source and angle. What problems might you face and how would you overcome them?
★ Group together all your classes’ windmills. Can you position them to make just one rotate when you turn on your wind source? What did you need to consider in order to do this? Can you position them to make all of them except one rotate when you turn on your wind source? What did you need to change in order to do this?
