Do Warmer Seas Make Stronger Hurricanes?

Science Fair Project Idea

Scientific Method

We've all heard that hurricanes draw their immense power from warm ocean waters. Of course, many factors contribute to the formation and growth of a hurricane, but can we expect to find that the warmer the water, the stronger the hurricane will be? This project shows you how to use online data archives to investigate this question. 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

Basketball: The Geometry of Banking a Basket

Science Fair Project Idea

Scientific Method

If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more

Using AI to Detect Proper Exercise Form

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how Artificial Intelligence (AI) can be used to improve human health and medicine? Computers can now identify human joints as key points to track our body movements. They can then use this information along with training data sets to show us if we perform exercises safely, to prevent us from getting injured. Create your own data set and test out if your algorithm can reliably detect good and bad exercise form. Read more

X-Ray Vision: Seeing Into Space

Science Fair Project Idea

Scientific Method

Have you ever seen amazing, colored images of objects in space, like stars or even entire galaxies? Some of these images were originally taken with forms of radiation that the human eye cannot actually see, like x-rays. In order to create the beautiful pictures you see in the news or online, scientists have to use an image-editing program to add color to them. In this astronomy science project, you will use raw x-ray data from NASA's Chandra X-ray Observatory telescope to create amazing… Read more

How to Make a Piano Sing

Science Fair Project Idea

Scientific Method

The renowned pianist Vladimir Horowitz once said, "The most important thing is to transform the piano from a percussive instrument into a singing instrument." In this project, you will learn how you can make piano strings sing using sympathetic vibrations. Find out which notes make another one sing the longest by measuring their sound intensities using a smartphone equipped with a sensor app. Read more

Classify Animals with Machine Learning

Science Fair Project Idea

Engineering Design Process

How do you tell the difference between a bird and a fish? Birds tend to have feathers and can fly, while fish have no legs and can breathe underwater. In this project, you will explore how to create a decision tree using machine learning that can classify different animals based on multiple characteristics. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot? Read more

Do People Use Different Passwords for Different Accounts?

Science Fair Project Idea

Scientific Method

Do you ever use a password to log in to a computer, email account, or website? Do you use the same password for each one? Even if your password is very long or hard to guess, using the same password for many accounts can still be risky. If someone manages to find out your password (for example, via a phishing attack, or if you write your passwords down and someone finds the piece of paper), they could easily access many of your accounts. However, memorizing lots of different passwords can be… Read more

Hit the Slopes: Build Your Own Ski Lift

Science Fair Project Idea

Engineering Design Process

Do you like winter sports like sledding or skiing? Check out this winter-themed engineering project to build your own miniature "ski lift." Use it to transport small objects from one place to another, just like a real ski lift transports skiers from the bottom of a mountain to the top. Read more

From Genes to Genetic Diseases: What Kinds of Mutations Matter?

Science Fair Project Idea

Scientific Method

Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. But sometimes a mutation actually does no damage. What kinds of mutations have to occur to cause a genetic disease? In this science project, you will explore online genetic databases to identify how a mutation in a gene can result in a dysfunctional protein, and how other mutations may have no effect at all.
