DIY Wind Turbines and How They Work

Earlier this week TED-Ed published a new lesson titled How Do Wind Turbines Work? The video covers the basics of how the turbines harness the power of wind to generate electricity. The basic math of wind turbine design is also explained to viewers of the video. Overall, it's a fine lesson but not the most detailed of lessons. If you want students to learn more about how wind turbines work, consider having them build their own small wind turbines. 

Microsoft's Hacking STEM website offers a detailed project guide for building model windmills and wind turbines. Not only will students build the windmills, they'll also capture data generated by their windmills. The data is captured in real-time through the use of Arduino and the Data Streamer add-in for Excel. Students then analyze the data to evaluate the effectiveness of their windmill and wind turbine designs. 

Microsoft's Hacking STEM windmill activity is great if you have the time and resources required to do it. If you don't and you'd like a little less in-depth windmill project, take a look at Instructables. There you will find dozens of windmill and wind turbine projects ranging from relatively simple cardboard creations to full-fledged turbines capable of powering appliances. 

Finally, if you haven't seen the TED video of William Kamkwamba sharing his story of building a windmill, you need to watch it. It's the basis of the book The Boy Who Harnessed the Wind

Learn Engineering - Dozens of Short Lessons About Machines and More

Learning Engineering is a nice website offering dozens of short video lessons about machines, materials, and energy. The site is organized into three primary sections; electrical engineering, mechanical engineering, and civil engineering. Within each category you will find sub-categories and topics for further exploration. Each topic is explained with a video along with a set of diagrams and text explanations. Check out the wind turbine video and diagrams to get a sense of what Learn Engineering is all about.


Applications for Education
The videos on Learn Engineering a bit dry, but they are clear. The combination of the videos with diagrams makes Learn Engineering a good resource for students to use as review materials after a lesson that you have taught.
