Batteries: The Shocking Truth
Science Fair Project Idea
Scientific Method
You probably use batteries to power different devices every day, ranging from toys to TV remotes, without giving it much thought. Figure 1, below, shows some common types of batteries. Eventually the batteries will die and you have to replace them with new ones (or recharge them if they are rechargeable batteries). How much do you actually know about how batteries work? This abbreviated project idea will give you some suggestions to investigate how batteries perform in common household… Read more
Solar Speedway
Science Fair Project Idea
Scientific Method
Solar power is hot these days. Gleaming, black solar panels soak up rays on more and more rooftops of homes and businesses providing a clean, alternative source of heat and electricity. You might guess that different times of the day yield different levels of solar power. But just how much does the sun's position in the sky affect the power that solar cells and panels can generate? That's the question this project is all about. Read more
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
Renewable Energy Resources
Science Fair Project Idea
Scientific Method
Coal, gas, and oil are energy resources that are not renewable, meaning that once we use up the world's supply of these natural resources there will not be any left. There is a lot of debate about how long these resources will last. One way to ensure that we will not find ourselves in an energy crisis is to develop energy resources that are renewable. Renewable energy is a resource that cannot be used up. Investigate the many uses of renewable energy: solar energy, wind energy,… Read more
Green Your PC: Help Your Computer Save Power
Science Fair Project Idea
Scientific Method
Is your PC an energy hog? Check out this science fair project to determine how much power your PC really uses, and if it is an energy hog, how you can reduce its appetite for energy. You'll learn how to profile and streamline your computer's power usage, while still enjoying every feature of your machine. Read more
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.
