Science Fair Project Idea

Engineering Design Process

Do you love playing video and computer games? Do you dream of someday creating your own? With this science fair project you can turn that "someday" wish into a "today" reality! Read more

Power Play: How Does Animation Timing Affect Your Perception of Game Action?

Science Fair Project Idea

Scientific Method

"Pow!" Wow, what an awesome punch that character has! Ever wondered what goes into making a punch look good in a video game? Or any other character motion sequence, for that matter? Try this science fair project for a firsthand look at how art and timing can create memorable game action. Read more

Is It Ripe Yet? Build a Circuit to Detect Ripe Produce

Science Fair Project Idea

Scientific Method

When you go to the supermarket, how do you pick out ripe fruits and vegetables? You might look at their size or color, or feel them for firmness. That might be easy to do when you pick out a half dozen apples, but imagine if you had to examine thousands of apples growing in a field, or strawberries coming down a conveyor belt getting ready for packaging. Suddenly, it is a lot harder to do yourself! What if a machine could pick and sort the produce for you? In this project, you will address part… Read more

The Surprising Strength of Eggshells

Science Fair Project Idea

Scientific Method

Have you ever seen an arch structure in a building, such as over a doorway or surrounding large windows? Arches have been used for structural engineering since ancient times. This experiment tests the strength of a naturally occurring arch shape: the shell of an egg. How much mass do you think an eggshell can support? Read more

2022 Paper 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? You can see how other students have tackled this and other annual Science Buddies Engineering Challenges. Read more

Remove Silver Tarnish with a Homemade Battery

Science Fair Project Idea

Scientific Method

Have you ever wondered why silver jewelry that starts out nice and shiny turns brownish-black and dull over time? The brownish-black stuff is called silver tarnish, and it is the result of a chemical reaction on the silver's surface. Luckily, there are many ways to clean tarnished silver and make it shiny again! In this science project, you will explore how to clean tarnished silver using electrochemistry. The electrochemical silver cleaning reaction requires aluminum and a salt solution. Your… Read more

Rusting Out: How Acids Affect the Rate of Corrosion

Science Fair Project Idea

Scientific Method

Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more

How Old Is the Universe?

Science Fair Project Idea

Scientific Method

Would it surprise you to learn that no one knows the exact age of the universe? Astronomers have estimates, and as they gather increasingly precise data and measurements, they continue to refine those estimates to come up with more accurate estimates. In this project, you can look at data about stars in dense groups called globular clusters and come up with your own estimate for the minimum age of the universe. How closely will your estimate match those of other astronomers? Read more

3D Print a Drone Frame

Science Fair Project Idea

Engineering Design Process

Drones come in all shapes and sizes. In this engineering project you will design and 3D-print your own frame for a miniature drone. Read more

Cricket Wicket Knockdown Challenge

Science Fair Project Idea

Scientific Method

In this cricket-inspired engineering challenge, you will build a machine to launch a ball and knock down a target (called a wicket). How many times can you knock down the wicket in three minutes? Teachers, lesson plan versions of this challenge are also available. Read more
