Astronaut Stress Management Training for Space Flight

Science Fair Project Idea

Scientific Method

Training for space flight isn't just a physically demanding job. You need to be prepared mentally and emotionally, too! In this science project, you will test how a breathing technique can improve your fight-or-flight response induced by the stressors of space flight. Read more

The Dynamics of a Bouncing Ball

Science Fair Project Idea

Scientific Method

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back! What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing. Read more

Why Aren't All Medicines Pills?

Science Fair Project Idea

Scientific Method

No one likes shots, so why don't we swallow all our medications? In this science project, you will use a model to explore one challenge behind making medications we can quickly swallow, using insulin (a medication taken by some diabetes patients) as an example. Will your medication be functional after spending time in an environment similar to the stomach? Read more

Minding your Mummies: The Science of Mummification

Science Fair Project Idea

Scientific Method

Have you ever seen or heard of the movies The Mummy or The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog. Read more

How Salty Does the Sea Have to Be for an Egg to Float?

Science Fair Project Idea

Scientific Method

Some objects float on top of the ocean, and other objects sink to the bottom. Why? Try this eggsperiment to find out! Read more

Build a Raft Powered by Surface Tension

Science Fair Project Idea

Scientific Method

Have you ever wondered why a water strider can walk on water? Or how detergent can clean your dishes? If you observe carefully, you can find dozens of similarly interesting phenomena that are all linked to the surface tension of water. In this science project, you will investigate the properties of water surface tension. Read more

Generate Customized Study Flashcards with Artificial Intelligence

Science Fair Project Idea

Engineering Design Process

Have you ever needed to make a lot of flashcards for a class, but didn’t have the time–or weren’t sure how to make ones that actually help you learn? Maybe you like studying on the go, or you’re trying to squeeze in a quick 10-minute review session between other things. In this project, you will learn how to use ChatGPT (or another AI tool of your choice like Gemini, Copilot, etc.) to generate effective study flashcards quickly and customize them to fit your class and… Read more

Design Your Own Slime

Science Fair Project Idea

Engineering Design Process

There are many different kinds of slime out there. Some slime is runny and liquid-like; other slime is thick and rubbery. Some slime glows in the dark, some is fluffy, and some is even magnetic! What set of properties makes the best slime? What kind of slime would you choose to make if you were selling slime as a toy in your own "slime shop"? In this project, you will experiment with different slime recipes and try to perfect one to make the best slime. Read more

Volleyball Machine Challenge

Science Fair Project Idea

Engineering Design Process

Can you build a volleyball machine? It will need one part to launch a ping pong ball over a net and another to return the ball. How many back-and-forth volleys can you get before the ball touches the ground? Looking for inspiration? You can see how other students have tackled this and other annual Science Buddies Engineering Challenges. Teachers, lesson plan versions of this challenge are available. Read more

Molecular Scissors

Science Fair Project Idea

Scientific Method

Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change the sequence of the DNA. Will the same enzymes still cut the new DNA sequence? Read more
