Can Humans Recognize AI-Generated Images?

Science Fair Project Idea

Scientific Method

Can you tell if the pictures on this page are real or generated by a computer? Artificial intelligence (AI) generated images have exploded in popularity, bringing plenty of controversy along with them. An AI-generated image of a tiger or a flower might seem harmless, but artificial images of people or events can contribute to "fake news." In this science project you will investigate whether people can tell the difference between real pictures and pictures generated by AI. Can you spot the… Read more

Recycle Urine into Drinking Water for Astronauts

Science Fair Project Idea

Scientific Method

Have you ever wondered how astronauts eat and drink in space? Where does their food and water come from? Water, in particular, is quite heavy, so delivering it to space is incredibly expensive. Instead, on spaceships and space stations like the International Space Station (ISS), it is most efficient to recycle water. This includes recycling urine! In this science project, you will use methods similar to those used on the ISS to investigate how urine can be recycled into clean drinking water. Read more

Remove Microplastics from Water with Bioremediation

Science Fair Project Idea

Scientific Method

Have you ever walked by an ocean, lake, or river and seen plastic trash? Have you ever wondered how microplastics might be impacting the creatures living in these places? In this science project, you will investigate how yeast can be used in bioremediation to remove microplastics from contaminated water. Read more

Teaching Machines to Understand Sign Language

Science Fair Project Idea

Engineering Design Process

Can AI understand human language? In the future, AI could aid in emergency interpretive service in the hospital when translators aren't available. But can current AI algorithms understand non-verbal languages like sign language? In this science project, you will test whether AI can learn sign language gestures or phrases to see if it can be used for interpretation. Read more

Admit it, you've probably launched a rubber band at least once—pulled one end back, and let it go flying. Did you ever suspect that rubber bands could also be a fun way to learn about physics and engineering? Find out in this project where you'll build a rubber band-powered car. Read more

Now You're Cooking! Building a Simple Solar Oven

Science Fair Project Idea

Scientific Method

Here is a project that uses direct solar power, gathering the sun's rays for heating/sterilizing water or cooking. It is a low-cost technology that seems to have everything going for it. Does it work? Can you find ways to improve it? Find out with this project. Read more

2026 Ball Run Challenge

Science Fair Project Idea

Engineering Design Process

In this engineering challenge, you will build a ball run from paper and tape, but there's a twist! You want to make your ball run as slow as possible. How long can you make it take for the ball to get from the entrance to the exit? Read more

Marble Roller Coaster: How Much Height to Loop the Loop?

Science Fair Project Idea

Scientific Method

This is a really fun project even if you don't like going on roller coasters yourself. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much of an initial drop is required to get the marble to "loop the loop." It's a great way to learn about how stored energy (potential energy) is converted into the energy of motion (kinetic energy). Read more
