Heart Health: How Does Heart Rate Change with Exercise?

Science Fair Project Idea

Scientific Method

Your heart starts beating before you are born and keeps right on going through your whole life. Over an average lifetime, the human heart beats more than 2.5 billion times. Keeping your heart healthy means eating right, not smoking, and getting regular exercise. Which of your favorite physical activities give your heart the best workout and help keep it fit? In this science project, you will use a smartphone equipped with a sensor app to visualize your heart rate and find out which… Read more

Predicting Future Water Quality with Machine Learning

Science Fair Project Idea

Scientific Method

Understanding the water quality of our rivers, streams, and lakes is critical for maintaining healthy ecosystems and sources of drinking water. Dissolved oxygen is one key water quality measurement that impacts aquatic life. But how can we predict how water quality might change in the future so we can intervene to keep our water healthy? With machine learning! In this project, you will gather water quality data for a location of your choice and use a random forest model to predict future… 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

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

Effect of Friction on Objects in Motion

Science Fair Project Idea

Scientific Method

The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction. Read more

Bouncing Basketballs: How Much Energy Does Dribbling Take?

Science Fair Project Idea

Scientific Method

Playing basketball can be hard work. Players not only constantly run around the court, but just dribbling the basketball takes a lot of effort, too. Why is that? It has to do with how the basketball bounces. When the ball hits the court, its bounce actually loses momentum by transferring some of its energy into a different form. This means that to keep the ball bouncing, players must continually put more energy into the ball. In this sports science project, you will determine how high a… 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

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

Modeling Your Local Watershed and Nutrient Pollution

Science Fair Project Idea

Scientific Method

Have you ever been unable to swim in a body of water because it was polluted? Have you ever wondered where the water came from, or what contributed to its pollution? In this science project, you'll learn how water drains to common areas to create bodies of water and how the land surrounding a waterway can contribute to its health and pollution. Read more

Using the Solar & Heliospheric Observatory Satellite (SOHO) to Measure the Motion of a Coronal Mass Ejection

Science Fair Project Idea

Scientific Method

The sun sometimes releases huge bursts of electrified gases into space. These bursts are called coronal mass ejections (or CMEs). When CMEs are directed towards Earth they can generate auroras, the spectacular atmospheric displays also known as "northern lights" (photo by Chris VenHaus, 2001). In this project you'll use images from the SOHO satellite to measure how fast CMEs move. Read more
