Science Fair Project Idea
You have probably heard about using renewable energy sources like wind and solar power to provide electricity to homes and buildings, as well as hybrid or fully electric cars that use less (or zero) gasoline. But what about solar-powered robots? As robots become more common, it is increasingly important to use "green" energy sources to power them. In this project, you will build and test a popular robot called a bristlebot — a tiny robot made using toothbrushes—that can operate on… Read more

Have you ever wondered how a radio can grab signals that are transmitted through the air and convert them into sound? In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. Read more

Time Required Average (6-10 days)
Prerequisites To do this science project, you must live in an area where you can receive at least one strong AM radio station. You can check for this with a car or portable radio.
Material Availability Specific circuit items are required. A Science Buddies kit is available for your convenience. See the Materials and Equipment list for details
Cost Average ($40 - $80)
Safety Never operate your crystal radio during a thunderstorm. When not in use, always disconnect your antenna from the radio circuit, and connect it directly to the ground rod. Be sure to wear safety goggles when installing the ground rod, especially if you are using a metal hammer. An adult's help might be necessary for some steps in the Procedure.

Cars that can drive themselves might sound like science-fiction, but they are a reality. Self-driving cars are cars that use sensors and computer programs to automatically drive on roads, without intervention from a human driver. However, the cars still have to follow all the same rules of the road as human drivers, including staying in the correct lane, obeying road signs and traffic lights, and avoiding obstacles like potholes or fallen tree limbs. In this project you will build a simplified… Read more

Science Fair Project Idea
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

You probably know that turning off the lights and the water, and not wasting paper are all ways to help the environment and conserve our resources. Did you know that another way is to use fuel cells? A fuel cell is a device that converts the energy in chemicals to electricity and it creates no pollution. The starting chemical does not have to be something complex — in fact you it can even be water! In this science fair project try your own hand at converting water to electricity with the… Read more

Here is a riddle for you: name an instrument that you play with your hands but never actually touch. Have you guessed the answer? It is a theremin! This unusual instrument makes sound without anyone touching it. How does a theremin work? It has an antenna that can detect the player's hand nearby, and as they move their hand around the theremin, the sound it makes changes based on the hand's position. In this music science project, you will get to use your own mini theremin to investigate… Read more
