What's the Best Exposure Time for Sun Print Paper?

Science Fair Project Idea

Scientific Method

Did you know you can make paintings or drawings using sunlight? You can do it by leaving objects on top of special sun print paper until the light creates an imprint of the objects. How does this process work? How long should you leave the paper in the sun to get the best result? What does any of this have to do with the process of making the microchips that power our phones and computers? Try this project to find out! Check out this page for more science projects related to this process. Read more

Build a Solar-Powered Bristlebot

Science Fair Project Idea

Scientific Method

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

Do Submarines Need Fins?

Science Fair Project Idea

Scientific Method

What keeps a submarine from spinning out of control? In this science project, you can investigate how submarines use stabilizing fins to move forward. You might even figure out the secrets to maneuvering a submarine! Read more

Find the Horsepower of a Toy Car

Science Fair Project Idea

Scientific Method

Have you ever heard someone describe how much horsepower a car has? Why do we use horses to measure how powerful cars are? What exactly is horsepower? How is horsepower related to things like speed and torque? Find out in this fun science project as you use a simple setup to find the horsepower of a battery-operated toy car. Read more

Build a Light-Tracking Bristlebot

Science Fair Project Idea

Scientific Method

Sometimes engineers get ideas to build robots from animals in nature. There are robot dogs, robot snakes, robot birds, robot cheetahs, and even tiny robotic insects! In this science project, you will build a robot insect of your own. The robot will automatically drive toward a light source, mimicking a behavior called phototaxis, seen in some insects. You will build your own robot and then make adjustments so it can reliably drive toward a light. Read more

Rusting Out: How Acids Affect the Rate of Corrosion

Science Fair Project Idea

Scientific Method

Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more

Which Materials are the Best Conductors?

Science Fair Project Idea

Scientific Method

Electricity powers many of the devices we use every day, from lights to video games and computers. Engineers have to use certain materials to make electrical devices work. In this experiment, you will find out which materials let electricity flow through them (conductors) and which ones prevent electricity from flowing through them (insulators). Read more

Effect of Friction on Objects in Motion

Science Fair Project Idea

Scientific Method

The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction. Read more

Marble Machine

Science Fair Project Idea

Engineering Design Process

Put your engineering skills to the test to see if you can build a machine—powered by nothing but gravity—that will automatically sort out two different sizes of plastic spheres. That might seem like a strange task, but have you ever used a coin sorter to separate pennies, nickels, dimes, and quarters? How about using a sifter in the kitchen to separate fine grains of flour or sugar from bigger lumps? Machines that can automatically sort objects or particles of different sizes are… Read more

Paper Circuits: Make Electrifying Art

Science Fair Project Idea

Scientific Method

"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
