Science Fair Project Idea
Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! Read more

Science Fair Project Idea
The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity. You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity. Read more

Peripheral vision is important in our everyday lives because it allows us to gather a visual sense of our surroundings—without it, we would see the world through "tunnel vision." The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do—from riding a bike, to dribbling a basketball, to reading a book—depends on peripheral vision. In this human biology science fair project, you will test… 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
Elec_p014

- Less Details
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.

Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings. Read more

Don't you just love listening to music? In the 1980s, people listened to music on the Sony® Walkman®. Now, people listen to their favorite tunes on MP3 players and on their Apple® iPhonesTM. But listening to music on devices actually started in the late 1800s and early 1900s. In those days, people would gather around their phonograph to listen to their favorite tunes—people were just as amazed with the phonograph as you would be to handle an iPhone. In this physics science… 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

Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity). In this project, you will construct simple devices that hold several germinating seeds, which allow you to watch how growing rootlets respond as you rotate the devices, effectively altering… Read more
