Is a Deleted File Really Gone?

Science Fair Project Idea

Scientific Method

When you delete a file, by accident or on purpose, is the information really gone? Can you get it back? If you accidentally deleted your five-page report for school, you may be hoping it is not really gone. On the other hand, if you do not want someone to get their hands on the goofy and unflattering pictures you and your best friend took while staying up late the other night, you probably hope the files you deleted are gone for good! Computer experts are often asked about file recovery.… Read more

It's Hard Work to Work Harden! Learn How to Make Metals Stronger

Science Fair Project Idea

Scientific Method

It's easy to forget that metals are everywhere and in nearly everything. They are a part of our lives in so many ways that we hardly notice them. But just stop and think about it. We use metal spoons to eat and cook our food. Cars, bikes, and planes are composed of metals. Metals are in our furniture and part of your school supplies. Some people even have metal in the dental work in their mouths. Their strength and dependence is obviously very important. But what are metals? In this science… Read more

Keep Your Candy Cool With the Power of Evaporation!

Science Fair Project Idea

Scientific Method

Did you know that your body has a built-in cooler? And it might not be what you think! Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair project, you'll use the energy produced when water evaporates to cool down chocolate-covered candy so it doesn't melt. Read more

Keeping You in Suspens(ion)

Science Fair Project Idea

Scientific Method

Suspension bridges, with their tall towers, long spans, and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? This science project shows you how to find out. Read more

Knock Your Blocks Off: The Mechanics of Carnival Games

Science Fair Project Idea

Scientific Method

"Hey kids, step right up! Toss this ball and win a prize!" shouts the carny barker. Sounds easy enough—until you try it. Why are those "simple" games at the fairs, carnivals, and boardwalks so hard? Is it really lack of skill or coordination or do those concessionaires use some basic laws of science to help them set up the games in their favor? This science fair project can help you find out for yourself. Read more

Let's Go Fly a Kite!

Science Fair Project Idea

Scientific Method

Kites have been a source of entertainment for centuries for kids from cultures around the world. In this science project you will have a chance to build your very own kite, a simple sled kite. Then you will use it to investigate how kites fly. Will you find out the best way to fly your kite? Read more

Levitating Magnets: Floating Isn't Just for Magicians

Science Fair Project Idea

Scientific Method

Have you ever seen a magician float an object in the air? If so, you might think that levitation (making things float) is just a magic trick, but the truth is you can use an invisible physical force to levitate a magnet! Try this science project to find out how. Read more

Lift a Load Using Hydraulics

Science Fair Project Idea

Scientific Method

Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… 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

Make a Motion Sensor Alarm with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Have you ever wished you could create an alarm system to guard your stuff? Or what about throwing a surprise party for someone and automatically playing music and flashing lights when they walk in the door? You can do either of these things using a Raspberry Pi. The kit includes a motion sensor, which can detect when people move in front of it. Check out the video to see what this simple, but fun, project looks like. IMPORTANT: The instructions for this project were originally written using… Read more
