Science Fair Project Idea
thumbnail Following a simple black line seems pretty easy, right? But think about it; how do you know what is the line and what is not the line? What if you wanted a robot to follow that line? How would it know what you wanted it to follow? Robots can use simple techniques to sense their surroundings and change their behavior based on what they see. In this engineering project, you will build your own robot that will follow a path without using complicated electronics or programming. Read more

Time Required Average (6-10 days)
Prerequisites You should be familiar with, or be willing to learn how to wire circuits on a breadboard. A little soldering is necessary to complete this science project, so you should also be familiar with the procedure or be able to find a helpful friend or adult.
Material Availability Readily available. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety If you are using the coping saw to make the wheels, use caution and be sure to wear safety goggles. Some steps require soldering, which involves very high temperatures. Use caution when soldering and when using other building tools. An optional step involves a product that must used in an open area, following the manufacturer's directions.
Science Fair Project Idea
thumbnail While trains that fly through the air might still be science fiction, trains that float just above the tracks without actually touching them are real and are actually used in a few countries today. This technology is called magnetic levitation. In this physics science project, you will build your own levitating train model and test how much weight it can hold before it stops hovering above the tracks. Read more

Science Fair Project Idea
thumbnail Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment.In this geology science project, you… Read more

Science Fair Project Idea
thumbnail It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick—it can make electricity! Electricity can be generated through the flow or through the fall of water. A big, fast-flowing river, for instance, contains a lot of moving energy that provides enough pressure to turn the blades of a turbine and run an electric generator. This same pressure can also be created though… Read more

Science Fair 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

Time Required Short (2-5 days)
Material Availability A drill is needed.
Cost Low ($20 - $50)
Safety An adult's help will be required to drill holes.
Science Fair Project Idea
thumbnail Water is an interesting thing. We drink it, swim in it, and wash ourselves with it. We can get energy from water by damming it and sending it through a turbine. But did you know that we can use the natural electrical charges present in water and a Kelvin electrostatic generator to create sparks? You can even use a Kelvin electrostatic generator to temporarily light a bulb! Now that is one bright idea! Read more
Elec_p069

- Less Details
Time Required Average (6-10 days)
Prerequisites None
Material Availability You will need to visit your local hardware store to purchase plumbing items to build the Kelvin electrostatic generator. You will also need a hand saw, a drill, a heat gun, a digital scale, a fan, and a dehumidifier. See the Materials and Equipment list for details. Cost of the project may be lower depending on what tools you already have available.
Cost High ($100 - $150)
Safety Parts of the Kelvin electrostatic generator require use of a hand saw and a drill. Wear safety goggles when using power tools. Adult supervision is required.
Science Fair Project Idea
thumbnail People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage, but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina to do all of the things that we want to accomplish, such as do our best in school and perform well in sports. But what makes a cardiovascular system unhealthy, and what are the… Read more

Science Fair Project Idea
thumbnail In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

Science Fair Project Idea
thumbnail Have you ever been so cold sitting in your house in the winter that you feel icicles could grow off your nose and your feet could turn into blocks of ice? Or have you ever been so hot in your house in the summer that sweat just drips off you? Making yourself comfortable can mean turning on the heater or the air conditioner—but that costs money. Still, being cozy or cool doesn't have to cost a lot of money if you use a geothermal heat pump. In this project you will build a model… Read more

Science Fair Project Idea
thumbnail Imagine that you could make an important piece of laboratory equipment in your kitchen. With this science project idea, you can! You will create your own centrifuge out of a salad spinner and some putty. In science labs, centrifuges are used to separate different liquids and/or solids from each other. You can load your homemade centrifuge with samples and see how they separate. What do you think happens to melted butter in a centrifuge? Read more
