Science Fair Project Idea
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

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

Science Buddies has several fun robotics projects, like the and , where you use arts and crafts materials to make part of a robot. Have you ever wanted to design a more-advanced, sturdier, or fancier looking robot? Then computer-aided design (CAD) and 3D printing might be for you; both are simpler than you think! The directions on this page will give you an introduction to these technologies so you can design and print your own robot. Figure 1 shows an arts-and-crafts version of an Art Bot… Read more

In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals cannot rely on sight. Did you know that you can also build a robot that uses "whiskers" to find its way around? This project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more

The movement of satellites is intriguing, but how do they orbit the way they do? Aerospace engineers run calculations and set up computer models to help them predict how satellites move in space, but in this astronomy science project, you will create a physical model with marbles, clay, and a cookie sheet to help you study how satellites move in space and learn from your observations.

Electric paint is a fun way to include a circuit with lights in an art project, but it presents a challenge not found in traditional electronic circuits. What happens if you change the length or width of your strokes of paint, such as by painting longer, curvier lines or using a thicker brush? Could this affect the electrical properties of your circuit? Try this project to find out! Read more

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Have you ever tried an apple that tastes like a banana? It sounds weird, but what actually makes the apple taste like an apple? Our tongue is definitely important for identifying food flavors, but if you have ever had a stuffy nose, you probably noticed that your smell contributes to taste as well. Which of those senses has more influence on flavor? Imagine eating an apple and, at the same time, smelling a really strong banana scent. How to you think the apple will taste? Will the nose or the… Read more

Have you considered where the gasoline that your parents put in your car comes from and how long that source will last? The fuel that most vehicles use, gasoline, is a petroleum product. Petroleum is a fossil fuel and is a nonrenewable form of energy, meaning we use it faster than it is able to be reproduced. Burning fossil fuels also produces pollutants that might hurt our environment. Using a kind of fuel from a renewable source would help save Earth's natural resources and cut down on… Read more
