Which Metal Is the Most Resistant to Corrosion?

Science Fair Project Idea

Scientific Method

Here's a practical engineering challenge: you need to build an enclosure for your dogs, using material that they can't chew through. It's going to be a lot of work to build, so you want to do it right. What material should you choose for the fencing? This project uses the scientific method to evaluate materials. Read more

Make a Greeting Card Come to Life!

Science Fair Project Idea

Scientific Method

A singing monkey? An elderly couple doing the chicken dance? What kind of funny electronic cards do you like to email people? Feel free to dream up your coolest and funniest card ideas, because in this science project, you'll create your own animated greeting card with a simple-to-use programming language called Scratch. Scratch is a programming language that makes it easy to create interactive stories, games, music, and art. When the program you have written is complete, you can even share it… Read more

How Can Life Survive on a Planet with Extreme Tidal Locking?

Science Fair Project Idea

Scientific Method

Have you ever wondered what life might look like on other planets? Life might need to survive conditions that would seem very extreme to us. Such conditions likely exist on planets that orbit abundant red dwarf stars. These planets can undergo tidal locking, which means one side is a perpetual, freezing night and the other is a perpetual, scorching day! How does life stand a chance? In this science project, you will test what extreme temperatures microscopic life can survive to model some of… Read more

It's Written All Over Your Face: The Science of Facial Expressions

Science Fair Project Idea

Scientific Method

Okay, now you've done it. You goofed off, didn't study for your math test, and didn't do well. Mom and Dad are not going to be happy. In fact, they might even be angry. They don't say anything when they see your test, but you can tell from their faces that they are angry. But how can you tell? How can you tell if someone is angry, or happy, or sad? The answer is that you have learned how to tell someone's emotional state from his or her facial expressions. Are facial expressions of happiness or… Read more

The Wagon Wheel Effect

Science Fair Project Idea

Scientific Method

Have you ever seen a video where it looked like a car's wheels were spinning backward even though the car was driving forward? What about helicopter blades that looked like they were spinning very slowly, or even not moving at all? This illusion is called the "wagon wheel effect," named after old movies where it looked like wagon wheels were spinning backward. In this science project you will learn how the wagon wheel effect works and how you can film it yourself. Read more

Save a Life! Teach Hands-Only™ CPR

Science Fair Project Idea

Scientific Method

What would you do if you saw one of your friends lying on the floor, not breathing, possibly having a heart attack? Call 911? Start CPR (cardiopulmonary resuscitation)? Those would both be important things to do! But do you know CPR? Do your friends and family know CPR? Chances are, most of them don't. Even if they do know CPR, they might be hesitant to use their mouths to perform it. You can change that though. In this science project, you'll create a simple, interactive game that can teach… Read more

The Wright Stuff: Using Kites to Study Aerodynamics

Science Fair Project Idea

Scientific Method

The Wright brothers used kites extensively to test their design ideas in the years leading up to their first successful airplane flight. With this science project, you'll learn about kite aerodynamics, and then come up with your own hypothesis about building or flying a kite. You can test your hypothesis two ways: with an online kite simulation program from NASA, and outdoors with the real thing! A great feature of this science project is that it has many possible variations, so you can decide… Read more

Mix It Up: Transferring Heat by Convection in a Tank

Science Fair Project Idea

Scientific Method

Big, puffy, cotton-like clouds, and the bubbles in a pot of boiling water may not seem like they have much in common, but they do—both are formed by a heat-transfer process called convection. Warmed gases and liquids rise, while cooler ones fall, creating currents and mixing things up. Whether making processed foods in a factory or making plastic or metal parts, knowing how to mix up a big tank of hot and cold liquids or gases quickly is important. Engineers must rely on experimentation… Read more

The Role of Fats in Making a Delicious Pastry

Science Fair Project Idea

Scientific Method

Apple pie is one of America's traditional desserts. It can be enjoyed on its own or with a scoop of vanilla ice cream. The cool sweetness of the ice cream combines with the warm apples and flaky pastry to create a taste sensation. However, if the pastry that surrounds the apples is heavy or chewy then that can really affect how much you enjoy this treat. But how do you make a pastry that is light and flaky? In this cooking and food science fair project, you will find out by experimenting with… Read more

Sorting Out Sedimentation

Science Fair Project Idea

Scientific Method

Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. How do sediments form? How are sediments of different shapes, sizes, and types sorted during the process of sedimentation? Find out in this science fair project! Read more
