Build a Bird Feeder and Study the Birds in Your Backyard!

Science Fair Project Idea

Scientific Method

In this fun science project, you will create a bird feeder from recycled materials that you can set up outside. By observing the birds that come to the bird feeder, you will find out what different kinds of birds live in your area. How many different kinds of birds do you think you will spot? 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

An Experiment on Nitrogen Fertilizers

Science Fair Project Idea

Scientific Method

Plants need nitrogen to grow healthy stems and leaves. Although nitrogen is the most abundant element in the air we breathe, that form of nitrogen cannot be used by plants. Nitrogen contained in fertilizer, on the other hand, is readily taken up by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more

Separating Butter with a Salad Spinner Centrifuge

Science Fair Project Idea

Scientific Method

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

Dome Sweet Dome

Science Fair Project Idea

Scientific Method

Have you ever seen a geodesic dome? Geodesic domes are approximately sphere-like (or partially sphere-like) structures made up of interconnected triangles. A famous geodesic dome is Spaceship Earth at EPCOT in Walt Disney World, Florida, but geodesic domes are also commonly found as climbing domes at playgrounds. In this science project, you will get to build a geodesic dome using rolled-up newspapers and tape. How much mass do you think your dome will be able to support? Build one and find out! Read more

MrBeast "Protect the Prize" Challenge

Science Fair Project Idea

Engineering Design Process

MrBeast, the world's most famous YouTuber, has a series of challenge videos where he asks a contestant to protect some valuable prize - like a pile of money or an expensive car - from a series of attacks like explosions, giant fireballs launched from catapults, or even getting hit by a train! Contestants often have only 24 hours to build something to protect their prize, which presents a very interesting engineering challenge. Given limited time and access to materials, how can you best protect… Read more

Fantastic Fossilization! Discover the Conditions For Creating the Best Cast Fossils

Science Fair Project Idea

Scientific Method

Have you ever stood close to a fossilized T. rex skull and counted its razor-sharp teeth? Or, have you seen a fossilized stegosaurus skeleton and thought about how it defended itself with tail spikes and armored plates? A trip to a natural history museum lets you imagine what dinosaurs looked like and wonder what life with them on Earth was like. Fossils give us information about animals and plants that lived long ago. Certain places around the world contain more fossils than others. Why?… Read more

Nothing But Net: The Science of Shooting Hoops

Science Fair Project Idea

Scientific Method

Swish! What a great sound when you hit the perfect shot and get nothing but net. Here's a project to get you thinking about how you can make that perfect shot more often. Read more

How Antacids Relieve Heartburn

Science Fair Project Idea

Scientific Method

Have you ever experienced heartburn after eating a large, greasy meal? Or have you heard of someone complaining about heartburn pains? It's very common; over 60 million people in the U.S. have heartburn at least once every month. Heartburn pain usually results from stomach acids escaping from the stomach and irritating the esophagus above it. Luckily, there are medical drugs, called antacids, which can help relieve heartburn pain. But how do antacids work, and how effective are they? In this… Read more

Hands-on Shopping: More Likely to Buy if You Can Give It a Try?

Science Fair Project Idea

Scientific Method

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
