Hacking the Air Gap: Stealing Data from a Computer that isn't Connected to the Internet

Science Fair Project Idea

Scientific Method

You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use a smartphone equipped with a sensor app to demonstrate how the data can be picked up by a nearby… Read more

Happy or Sad? Use Artificial Intelligence to Classify Faces

Science Fair Project Idea

Engineering Design Process

Do you think artificial intelligence (AI) is too complex to use? Think again! In this project, you will use AI to teach a web-based tool to classify happy and sad faces, or other objects, poses, or sounds. This experiment requires no coding skills; instead, you will need curiosity, creativity, and a critical eye. Why not give it a try yourself? Read more

How High Can You Throw a Baseball? A Tennis Ball? A Football? A Golf Ball?

Science Fair Project Idea

Scientific Method

How high can you throw different types of balls, like a golf ball, a basketball, and a football? Would one of them go higher than the others? Do factors like mass, shape, and volume influence the final height? You can measure the approximate maximum height a thrown ball reaches by measuring the time it spends in the air. To do this project, you'll need at least one ball and a helper with a stopwatch. Your helper should start timing just as you release the ball, and stop right when the ball… Read more

How Much Current Does It Take To Blow Up An LED?

Science Fair Project Idea

Scientific Method

Have you ever accidentally burned out an LED while building a circuit? What about doing it on purpose—for science, of course! In this science project, you will intentionally send too much current through LEDs to see if they will burn out or even explode! How much current does it take to destroy an LED? How does this compare to the LED's rated current value? Try this project and find out! Check out this page for more LED science projects. Read more

How Well Do Different Materials Create Static Electricity?

Science Fair Project Idea

Scientific Method

When your parents were kids, they probably wore polyester. Static cling was a major household issue! Now everybody wears cotton, which does not get static cling nearly as much. Why are some materials more susceptible to static cling than others? Investigate how well different materials produce static electricity by making a homemade electroscope and testing it out in this science project. Read more

Identify Road Signs with Machine Learning

Science Fair Project Idea

Engineering Design Process

Driverless cars use machine learning, a type of artificial intelligence, to identify road signs and other things they encounter on the road, like pedestrians and other vehicles. In this project you will take your own pictures of different types of road signs and use machine learning to identify the signs using a free online tool (no programming is required). You will then attempt to improve your machine learning model so it can identify signs in a variety of environments. Read more

Investigating the 'Mpemba Effect': Can Hot Water Freeze Faster than Cold Water?

Science Fair Project Idea

Scientific Method

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out as we expect! Read more

Is There Such a Thing as Too Much Gaming?

Science Fair Project Idea

Scientific Method

Have you ever heard someone described as a video game addict? Do you think video game addicts actually exist? You can determine that for yourself in this science fair project by examining real data from a California research scientist for over 3,000 video game players! 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
