  1. HOW TO MANIPULATE WIND ENERGY OBJECTIVES: • Two ways glaciers move

  2. Is the ability to do work ENERGY RENEWABLE ENERGY SOURCE NON-RENEWABLE ENERGY SOURCE Energy source we can use over and over again Energy source we are using up and cannot recreate in a short period of time

  3. ANALYZING OUR SOURCE

  4. ANALYZING OUR SOURCE

  5. GENERATING WIND POWER 2 1 3

  6. GENERATING WIND POWER 2 Attach a voltage probe Attach a current probe 1 POWER = VOLTAGE x CURRENT 3

  7. LET THE GAMES BEGIN • Competition to see which group can build the most powerful wind device • Each group will discuss their plan for designing a wind-turbine: • Thickness of paper • How much tape • How much clay • Length of straw • Shape of the blade

  8. WINDMILL DESIGN & MATERIAL SELECTION • List at least 3 factors that make a wind-powered device a good alternative energy converter • Illustrate the shape of your windmill blades. What are the benefits of the shape you selected? • Which thickness did you select for your blade? Why? • How will you know if your blade design is effective and efficient?

  9. TRIAL AND ERROR • Describe the features of the most efficient windmill. List at least 3 features • What one variable will you change about your windmill to improve the efficiency of your model? • Did the changes you made improve the efficiency of your model?

  10. Sequence the cutting of the template to make it easier • Show students the one I built • Wrap straws with layer or two of tape to stop blades from sliding off one end (other end will have clay) • Bring handful of leads and jumpers • Make sure students test at 3 different speeds • MAKE EXCEL FOR STUDENTS TO INPUT THEIR I,V,P … • Make sure blade tips are not bent

  11. THINK OUTSIDE OF THE BOX HIGHWAY WIND TURBINE ROOFTOP WIND TURBINE
