You've Got Permission to Be a Backseat Driver!

Science Fair Project Idea

Scientific Method

Do you like to tell adults where to go and how to get there? Well, here's your chance to do it in the name of science! In this science fair project, you will see what happens to your car's fuel efficiency when it takes you downtown to see a movie, up a hill for a great view, or out for a cruise on a flat country road.

A Bright Idea for Saving Energy

Science Fair Project Idea

Scientific Method

In the United States, lighting for homes accounts for about 14% of all residential electricity usage (EIA, 2014). That's billions of dollars worth of electricity per year. The U.S. has passed legislation to phase out older, more inefficient incandescent light bulbs, and they are being replaced with newer, more-efficient bulb types like compact fluorescent lights (CFLs) or light-emitting diodes (LEDs). How much energy (measured in kilowatt-hours [kWh]) and how much money could be saved by… Read more

Free Lunch? Can Solar Energy Systems Pay for Themselves with Utility Bill Savings?

Science Fair Project Idea

Scientific Method

If you are interested in exploring how renewable energy can improve the environment, this project could be for you. You'll take on a real-life engineering challenge: deciding whether the benefits of a renewable energy technology are worth the cost to implement it. Some sample questions are suggested, but you can also come up with your own question that matches your specific renewable energy interest. Is there such thing as a free lunch? Read more

How Does Snow Cover Affect Solar Panel Power Output?

Science Fair Project Idea

Scientific Method

What happens when solar panels get covered in snow in winter? Does some sunlight make it through the snow? Does the power output of the panels drop considerably? Is it worth it to go scrape the snow off the panels if temperatures will remain below freezing? How hard is this to do for rooftop solar panels or a large solar farm? These are all questions you can answer yourself in a science project using a small solar panel and a multimeter (Figure 1). You can follow a procedure similar to those… Read more

Have you ever played with a toy pinwheel, or seen larger real-life versions like a windmill or wind turbine? Have you wondered why all the blades are symmetric? Why can’t they get away with just one blade? Try this project to find out! Read more

Spinning Your Wheels: Pinwheel Sensitivity

Science Fair Project Idea

Scientific Method

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

Have you ever ridden your bike into a strong wind? If so, did your legs feel like lead? How does this compare to how you feel when the wind is pushing against your back – does that make you feel ready for the Tour de France? In this science activity, you will explore how wind-powered devices, like wind turbines and pinwheels, also react in different ways to the direction of the wind. Read more
