Our Afterschool STEAM program will begin a 3-week unit on wind energy on February 27.  Students will first learn what wind is and where wind comes from.  They will build a windmill with Lego Machines and Mechanisms and study how the windmill design helps do work.  Next, they will learn about energy transfer and renewable energy as they build a Lego wind turbine connected to an energy meter.  Lastly, they will learn about aerodynamics and turbine blade design as they design their own blade to fit the Lego turbine, and see how their blade affects the energy efficiency of the turbine.  

Key Questions

How does a wind turbine work?

How does a wind turbine change kinetic energy to electrical energy?

What aerodynamic forces influence the design of the blades?

Expected Outcomes

I'd like students to be able to connect their small-scale Lego turbines to the real-world of wind farms and the benefits of wind energy, and to have an idea of the function of the turbine and the aerodynamics of the turbine blades.  



Curriculum Alignment

Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.* [Clarification Statement: Examples of devices could include electric circuits that convert electrical energy into motion energy of a vehicle, light, or sound; and, a passive solar heater that converts light into heat. Examples of constraints could include the materials, cost, or time to design the device.] [Assessment Boundary: Devices should be limited to those that convert motion energy to electric energy or use stored energy to cause motion or produce light or sound.]
