In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from one-inch PVC pipe and balsa wood (or recycled materials). This lesson plan is divided into three parts. In Part I, learners explore outdoors and examine where wind comes from. In Part II, learners review the power equation and wind as an energy resource. Finally, in Part III, learners work in groups to construct and test their wind turbines. During each section, learners can view video segments that are linked to this resource.
