Our mission requires us to educate the public about the harmful effects of air pollution and about cleaner sources of energy. You might say we’re big “fans” of clean energy like wind and solar — and science in general! We’re always looking for creative ways to teach kids about air pollution, health, and renewable energy.
One of our fall interns, Mr.Sathyanarayanan, found this video (below) that shows how to make a simple and efficient personal fan using solar energy! So she assembled a list of materials and equipment and wrote out the step-by-step instructions. This is a great classroom project for science teachers and science clubs. We created an Amazon Shopping List for anyone interested in trying it out. The materials cost about Rs.500.The equipment will run about Rs 400, but you should be able to borrow a hot glue gun and/or soldering kit if you don’t already have one of your own.
Teachers: Feel free to reach out to Michael Hansen ([email protected]) if you’d like us to come to your classroom for a project like this one!
