Lesson 11: Energy - 2 Grades 9-12 (could adapt these ideas for K-8) |
 |
| Possible Questions How do the shapes of Rickey sculptures use the wind to produce motion? How do the new “wind-farms” compare with “old-fashioned” windmills? How much energy can we produce from the wind? Where can we put “wind farms” in the future? Teacher help: Beginning/introduction: Directed discussion - why do we need to develop renewable energy use, drawbacks of wind-energy (variable, not much for each “wind-energy generator”) Middle: Hands–on: group discussions and writing their ideas about the questions raised - these could focus on the mechanics of wind-farms, how they are used to develop electricity, and how that electricity is included in the national electrical grid. Students develop a project how to build a windmill to produce energy at their school Summing up the experience: Whole class discussions How effective were the models in producing motion - how would you improve your models (note, not every group need be successful) Extensions: How much energy can we produce from the wind? How do the new “wind-farms” compare with “old-fashioned” windmills? Are we going to need more “wind farms” in the future? How does energy production from wind compare to that from sunlight?
