OverviewIn this lesson, students will design a working wind turbine with a goal of maximizing voltage output. After reviewing types of energy and energy transfer, students will split into groups. They will design and test multiple wind turbine blades using different materials and shapes. After determining the best blade type, students will construct their wind turbines. In the following class period, groups will formally test their turbines to determine which group's turbine produces the highest voltage output. Following the testing, the class will discuss generators and how wind turbines use them to produce electricity. An optional follow-up discussion can then take place about clean energy versus fossil fuels.Suggested Time: 100 minutesGrades: 9-11NGSS Standards:HS-PS2-5: Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.
