In physics class, you have probably rolled your eyes at some point after being assigned a "projectile motion" homework problem where you use equations to predict how a ball will move through the air. This experiment will show you just how fun that problem can be by using a real catapult to launch a ball and videotaping it as it flies along its path. Then, you will analyze the video and compare it to what the equations predicted. If you have ever wondered if those equations in your physics…

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate.

Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items, especially colored drinks, contain dyes with names such as FD&C Blue 1, Red 40, or Yellow 5. But how much dye is needed to create all these colors? In this chemistry science project, you will build a simple spectrophotometer that is able to measure the concentration of colored chemicals in solutions. You will test your device by measuring…

If someone asks you to draw a picture of a doctor, lawyer, or engineer, what first pops into your mind? The race and gender of the person you imagine might be shaped by your personal life experiences, such as whether you have family members in those professions, or what representations of them you have seen on TV or online. What do you think will happen if you ask an artificial intelligence (AI) program to generate the picture instead? Will pictures generated by AI reflect the true real-world…

Although some of us may not like to admit it, everyone's afraid of something. Big dogs, thunderstorms, public speaking, heights: what are you most afraid of? Do you think grown-ups have the same fears as kids? How about first-graders and sixth-graders? Find out for yourself by doing this project.

Have you ever gone to pour yourself a cup of milk and all you get is milk clumps? What happened to the milk is called coagulation, which is the mechanism that occurs when proteins in the milk clump together. While you do not necessarily want this in your milk, without coagulation (or curdling), there would not be any cheese or yogurt, which is why it is a very important process in the food industry. But what makes milk curdle? In this science project you will use pineapple juice to curdle milk…

Did you know that in addition to the Sun and planets, our solar system is filled with millions of asteroids, which are chunks of rock left over from the early days of its formation, or from collisions between larger objects like planets? Agencies like NASA track asteroids, not only because they might pose a threat to humanity by colliding with Earth, but because they can provide us with information about the history of our solar system, and even be useful for mining raw materials in space! In…

Artificial intelligence (AI) programs can now generate photorealistic pictures of people who do not exist in the real world. How can you tell if a picture is of a real person or a fake, AI-generated person? What features of the picture do people use to decide whether the face is real or AI-generated? In this project, you will explore these questions as you ask volunteers to look at both real and AI-generated pictures of human faces.

Sunspot activity has been monitored continuously since about 1700. The historical data shows that sunspot activity rises and falls in a roughly 11-year cycle. This project shows you how you can use both graphical and statistical analysis to look for patterns in cyclical data.

There is a lot of energy that can be harvested from moving water. Energy can be extracted from water rushing over a waterfall and from the regular patterns of the ocean's tides. The energy that propels waves forward in the oceans can also be extracted and used. But can wave energy power plants be built anywhere there is water? In this energy science fair project, you will use ocean buoy data and mathematics to determine which locations along the coasts of the United States can sustain a wave…

Scientists have known for hundreds of years that sunspot activity waxes and wanes over a cycle that lasts approximately 11 years. In the 1970's, scientists discovered that the sun periodically blasts electrified gases into space, in huge outbursts called 'coronal mass ejections,' or CMEs. This project asks the question: do CMEs follow the solar sunspot cycle?

Globular clusters, compact groups of about a million stars that move around together in galaxies, are among the oldest objects found in the universe. Since they are found in most galaxies and since they've been around for so long, globular clusters have a lot to tell us about what the universe looks like now and how it got that way. Is our Milky Way Galaxy just like all the other galaxies out there? What are galaxies made of? What can we learn about the universe from looking at galaxies? …
