Third Grade Energy & Power Science Projects (2 results)

Whether you are working, studying, or being entertained, much of our daily routines rely on being plugged-in. You probably don't spend a lot of time thinking about where all that power comes from, but someone has to! Figuring out the best ways to produce energy is a big job that is growing along with the world's population. Energy can also be a hot topic with argements about whether to invest in fossil fuels or clean renewable energies like solar, wind, water and geothermal. Take a first-hand look at some of the problems and challenges scientists and engineers are tackling as they look at making and storing energy in our collection of energy science and engineering projects.

Science Fair Project Idea
So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this science fair project, you'll blow on different kinds of pinwheels with a blow-dryer and see how far away you can get before they stop spinning. This will give you clues about how sensitive the pinwheels are to wind, and why. So come spin your wheels and get… Read more

Science Fair Project Idea
Have you ever been so cold sitting in your house in the winter that you feel like icicles could grow off your nose, and your feet could turn into blocks of ice? Or have you ever been so hot in your house in the summer that sweat just drips off you? Making yourself comfortable can mean turning on the heater or the air conditioner, but that costs money. Being cozy or cool does not have to cost a lot of money if you use a geothermal heat pump. In this project, you will build a model geothermal… Read more
