Science Fair Project Idea
 This project challenges you to figure out how to make geometric patterns with Rubik's Cube. Leaving your cube in one of these positions makes it much more tempting to pick it up and 'fix' it. Can you figure out how to make a checkerboard, or a cube-within-a-cube? Can you make only the center piece a different color from the rest? Can you figure out how to solve the cube from these positions? Read more

Science Fair Project Idea
 The Stroop effect describes an experiment about the time it takes to name the color of printed words. When you try to name the color in which color words are printed, it takes longer when the color word differs from the ink color than when the color word is the same as the ink color. This project is an interesting variation: what happens if you 'warp' the words into a curved shape that is harder to recognize as a word? Will the Stroop effect still happen? How 'warped' do the words have to be in… Read more

Science Fair Project Idea
 The ocean is a wondrous force of nature. It affects the weather, and provides us with food and free and renewable energy to power our lives. How can the ocean provide us with free and renewable energy? One way is to extract the energy that is in the waves. There are many kinds of power systems that can be installed to extract energy from the waves, depending on the location. In this energy and power science project, you will build and test a simple model of an oscillating water column device to… Read more

 Time Required Average (6-10 days) Prerequisites You should have fairly easy access to the ocean or to a deep body of water. Find a location where the surface of the water is within easy access of a pier, a dock, or a boat slip, and where the water is about 5 feet deep. You could also do this project in a swimming pool. Material Availability See the Materials and Equipment list for more details. Cost High (\$100 - \$150) Safety Be sure to wear safety equipment, such as safety goggles and gloves, when working with power tools and other equipment. Parental supervision is required.
Science Fair Project Idea
 Have you ever seen a cat chase a laser pointer or a flashlight beam? What if you could make a robot do that? In this project, you will build a robot that can automatically drive toward a bright light source. The robot uses a simple electronic circuit to track light, so there is no computer programming required! You can also do three other robotics projects using the same kit of parts, so this is a great way to get started with robotics before moving on to more advanced projects. Read more

 Did you know that the average child sees 20,000 30-second TV commercials in just one year? That's a lot of encouragement to buy new toys, clothes, entertainment, and food. In this behavioral science fair project, you'll find out some other ways (besides commercials) that marketers use to try and get adults to buy products, like having them touch or hold an item. You'll find out if these methods work with kids, too, and if they increase how much people are willing to pay for a product. It's a… 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

 Time Required Average (6-10 days) Prerequisites You should have the patience and dexterity to coil several layers of wire neatly (or find someone who can help you). You will also need to hook up a basic circuit. Understanding electric circuits is not a prerequisite for this science project, though it will enable a deeper understanding of the electric generator. Material Availability A kit containing all the specialty items needed for this project is available from the . Cost Low (\$20 - \$50) Safety Neodymium magnets are very strong. Follow the safety guidelines in the Procedure for working with these magnets.

 What happens if you hold a magnet next to water? You might think that water is not affected by magnetism, but in fact, the water is slightly repelled. Believe it or not, if the magnet is strong enough, you can use this effect to levitate objects that contain water, including insects and even small frogs! In this science project, you will learn about diamagnetism. Materials that are repelled by both poles of a magnet are called diamagnetic. The magnets you will use are not strong enough to float… Read more
