Build an Ultrasonic Levitator

Science Fair Project Idea

Engineering Design Process

It's not magic; it's science! Build your own acoustic levitator to make objects float in midair using invisible sound waves. Read more

Marble Roller Coaster: Converting Potential Energy to Kinetic Energy

Science Fair Project Idea

Scientific Method

If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track.

How to Build an X-ray Machine

Science Fair Project Idea

Scientific Method

When you have your X-rays taken at the dentist's or doctor's office, do you ever wonder how the X-ray machine works? Or better yet, how you could make one yourself to use for experiments? This how-to guide provides detailed instructions for high school students and adult do-it-yourself (DIY) enthusiasts to construct and use a homemade X-ray machine safely. Read more

Make a Biohybrid Robot

Science Fair Project Idea

Engineering Design Process

When you think of robots, you might think of things made out of plastic or metal...but what about living materials? Living materials have one big advantage: they can heal and repair themselves if they get damaged. Since it might not always be easy to repair a damaged robot (for example, a robot on another planet), some scientists want to figure out how to include living, or biological, materials in them to create "biohybrid" robots. In this project, you will create your own simple biohybrid… Read more

Dealing with Diabetes: The Road to Developing an Artificial Pancreas

Science Fair Project Idea

Engineering Design Process

Imagine if you had to take medicine every time you ate, and you had to use a math formula to figure out how much medicine to take based on the nutritional makeup of the food, how you were feeling, and what activities you were planning to do. You might also need extra medicine throughout the day (even in the middle of the night) based on your blood glucose levels. People with diabetes who take insulin do this every day. They use finger sticks and blood glucose meters or a continuous glucose… Read more

The Importance of Making Sure a Drug's Aim Is True

Science Fair Project Idea

Scientific Method

Scientists recently found that some small drugs can stop infection by the deadly Ebola virus in its tracks. Lab researchers found that these drugs bind to a protein that the Ebola virus uses to enter our cells, and this is how infection is prevented. However, this also means that the bound protein no longer functions in our cells. How might these drugs accidentally disrupt important biological processes in our bodies? What other proteins might these drugs bind to? In this science project,… Read more

Can You Train People to Breathe Better?

Science Fair Project Idea

Scientific Method

The practice of "belly breathing" has been linked to improve mood, relaxation, and even have physical benefits like lowering your heart rate when compared to chest breathing. However, most of the time, we do not think about breathing—our bodies do it automatically. How do you know if you are belly breathing instead of chest breathing? How can you practice and get better at it? In this project you will build your own device to provide visual feedback about how a person breathes, then see… Read more

Write a Program to Analyze Text and Guess the Author

Science Fair Project Idea

Engineering Design Process

Do you think you could figure out if two different anonymous messages were written by the same person? What about telling the difference between text written by a human and something written by artificial intelligence (AI)? How about identifying the author of a historical text? Each individual author may have their own personal style, and analyzing text mathematically can help you identify that style. Can you write a computer program that takes a passage of text as input, and calculates the… Read more

Planet Hunters TESS

Science Fair Project Idea

Scientific Method

The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorers program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. It was launched on April 18, 2018 atop a Falcon 9 rocket. During its two-year primary mission, it was expected to find more than 20,000 transiting exoplanets, compared to about 3,800 exoplanets known when it launched. The first light image from TESS was taken on August… Read more

Making a Cell Phone Spectrophotometer

Science Fair Project Idea

Scientific Method

We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by… Read more
