    • Wind Turbine Worksheet.

      • Pre-Activity Assessment

         
         

        Brainstorming: Have the students engage in open discussion to think of how wind could be used as an energy source. Remind them that no idea or suggestion is "silly." All ideas should be respectfully heard. Write their ideas on the board.

         
         

        Activity Embedded Assessment

         
         

        Worksheet: Have students record their measurements and observations on the Wind Turbine Worksheet. After they have completed the worksheet, review their answers to gauge their mastery of the subject.

         
         

        Post-Activity Assessment

         
         

        Question/Answer: Ask the students and discuss as a class:

         
           
        • When can wind power be used? (Answer: The wind must have a high enough speed.)
          •  
        • Why might an engineer be interested in developing wind power in a location? (Answer: Wind is a renewable energy resource. Wind power does not produce greenhouse gases or pollution. Using wind power reduces the consumption of non-renewable fossil fuels.)
          •  
        • Why are large wind turbines often located on hills? (Answer: Wind speed is greater up high above the ground.)
          •  
        • If we remove the motor from the rotor of the wind turbine, we will not be able to produce electricity, but we will still be able to do work with our windmill. What kind of work could we do? (Answer: We could do mechanical work by making the blades of the windmill move.)
          •  
         

        Engineer Challenge Question: Ask the students to think about the following engineering design problem. Have them discuss their answers in teams and share their thoughts with the class.

         
           
        • A homeowner wants to use a wind turbine to supply electricity for her home, but there are no hills near the house. Where could an engineer place the wind turbine? (Answer: As high up as possible, such as on a pole above the roof, or on a separate structure that puts it up very high in the air.)
