Project Idea
thumbnail You might know that we are able to get free energy from the Sun, the wind, and water, but did you know we can get free energy from Earth itself? The temperature inside of Earth can reach 9,000°F—that kind of heat can be used to make a lot of energy here on the surface! This source of energy is called geothermal energy and it is all about taking advantage of the heat within Earth. So try this science fair project out and find out how to use the heat that lies beneath your feet! Read more

Project Idea
thumbnail Earth is an amazing planet. It has everything that we need: food, shelter, and water. Sure, we need water to drink, but have you thought about using water to create energy? Moving water has a lot of energy and all we need to do is to harness it. Moving water made the Grand Canyon. That took a lot of energy! In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight. Read more

Project Idea
thumbnail Do you like getting something for nothing? Everybody likes getting things for free. How about getting energy and power for free? The Sun sends us free energy every second and all we have to do is collect it. Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how varying the angle of the solar panel, and thus the amount… Read more

Project Idea
thumbnail Have you ever wondered how fast a seismic wave from an earthquake travels? In this geology science project you can figure this out using historical seismograph data that you can collect from the comfort of your own computer. You will use a web interface to a network of seismometers run by the Northern California Earthquake Data Center, at the University of California, Berkeley. From the seismograms you make, you will be able to measure the time it took for the seismic waves to travel from the… Read more

Project Idea
thumbnail What's your favorite thing to do on the hottest day of the year? Dip your toes in an icy river? Hang out by the pool? Retreat to a cool basement? Lie motionless in the shade? You're probably not too eager to move around and put out a lot of energy, like mowing the lawn in the mid-afternoon sun. Well, you're not the only one. In this electronics science fair project, you'll find out that some semiconductor devices, like light-emitting diodes (or LEDs), act the same way. As their internal… Read more

Safety You should never look directly into an LED flashlight, as it can cause eye damage.
Project Idea
thumbnail Watching a space shuttle launch is an unforgettable experience. Solid fuel rocket boosters and the engines both overcome the massive weight of the shuttle, and even gravity, to blast a space shuttle into space. One issue with solid fuel rocket boosters and conventional rocket engines is that they require fuel, and fuel weighs a lot! In this electronics and electricity science fair project, you will learn about ion engine propulsion systems. These systems have advantages over the conventional… Read more

Project Idea
thumbnail Earth, the Sun, wind, and water are all sources of renewable and sustainable energy—and sources you probably already know about. But did you know that you can get energy from such things as banana peels, coffee grounds, and newspaper? In a process called composting, you can transform kitchen and other solid wastes into a product that is beneficial for your garden: homemade fertilizer. As the waste decomposes, it also creates heat. Can this naturally created heat be put to use? In this… Read more

Time Required Very Long (1+ months)
Prerequisites Making a compost pile can take anywhere from a couple of days to a few weeks, depending on the method and bin you use. In this energy and power science fair project, you will spend a few days creating a compost pile. You will have to account for the time as you are planning your science fair project. You will also need to be home for several hours at a time on many specific days throughout this project. Read through the Experimental Procedure for more details.
Material Availability You (and friends, if possible) will have to start collecting potato peelings or grass clippings a few weeks in advance to accumulate enough, so keep this in mind when budgeting time for your science fair project. See the Materials and Equipment list for details.
Cost Very High (over $150)
Safety Wear safety goggles and use caution when working with all tools. Be sure to wear disposable gloves when handling animal waste and to clean all of the work surfaces thoroughly with a bleach solution. Read the Science Buddies Microorganism Safety Guide to learn how to experiment safely.
Project Idea
thumbnail 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
