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

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.

Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more

How easy is it for you to walk along and follow a line that is painted on the ground? Simple, right? You might be able to follow a line without giving it much thought, but how could a robot do that? In this project, you will build your own automatic line-following robot that can race around a track that you create. This technology has plenty of real-world applications—maybe one day you could help design self-driving cars! Read more

Safety Short circuits can get very hot and present a burn hazard. Be careful to follow the directions in the Procedure in order to avoid short circuits when building your robot.
Science Fair Project Idea
The makers of sports drinks spend tens to hundreds of millions of dollars advertising their products each year. Among the benefits often featured in these ads are the beverages' high level of electrolytes, which your body loses as you sweat. In this science project, you will compare the amount of electrolytes in a sports drink with those in orange juice to find out which has more electrolytes to replenish the ones you lose as you work out or play sports. When you are finished, you might even… Read more

Science Fair Project Idea
When you think of a motor, you may immediately think of a car, but you actually encounter other motors in your home every day. That's right, if you put on clean clothes from the washing machine, ate food from the fridge, or used a fan, you used an electric motor. In this electronics science project, you will make a simple electric motor with two magnets that "talk" to each other. As they interact, they will alternate between "liking" each other (pulling together), and "disliking" each other… Read more

Time Required Average (6-10 days)
Prerequisites You should be able to coil wire neatly (or find someone who can show you how) in order to make your electric motor work.
Material Availability A kit containing all the specialty items needed for this project is available from the .
Cost Low ($20 - $50)
Safety

Never try to use a wall socket as power source for your motor.

Neodymium magnets are very strong. Follow the safety guidelines in the Procedure for working with these magnets.

Wouldn't it be nice to avoid those nasty electric shocks you get after you have walked around on carpet and then touch a doorknob? These shocks are caused by static electricity. In this project, you will build a super-sensitive charge detector to investigate the electric fields created by static electricity. The detector can sense invisible electric fields before you touch something and get zapped, so try this project to avoid the shock of shocks! Read more

When you go to the supermarket, how do you pick out ripe fruits and vegetables? You might look at their size or color, or feel them for firmness. That might be easy to do when you pick out a half dozen apples, but imagine if you had to examine thousands of apples growing in a field, or strawberries coming down a conveyor belt getting ready for packaging. Suddenly, it is a lot harder to do yourself! What if a machine could pick and sort the produce for you? In this project, you will address part… Read more

If you want to get your friend's attention at a crowded sporting event with lots of people cheering, you need to shout. If you're trying to do the same thing in a quiet library, a whisper works. The detection limit for each of our senses depends on the amount of "background" stimulation that is already present. This project uses an LED control circuit to investigate detection of changes in light levels. Read more

"Paper circuits" are a fun way to mix electronics and art by adding lights directly to a painting or drawing. These lights need a battery to power them, and typically you would use wires to connect them. In paper circuits, though, many materials can be substituted as "wire," including special types of paint, ink, and even aluminum foil. There are also different options for what type of battery you can use. Which materials do you think will work best? Try this project to find out! Read more

Do you want to trick friends and visitors with an amazing optical illusion? In this engineering design project you will learn how to build an infinity mirror,with built-in lights that make the mirror look like a deep tunnel with no end. But pick the mirror up and look behind it, and you will see that it is only a couple of inches thick! Read this project to find out not only how this illusion works, but how to design and build your very own infinity mirror from scratch. Read more
