Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much.

What do sand, Skittles, and cereal have in common? They are all granular materials, which means they are made up of solid particles, but they can actually flow like liquid! Imagine pouring the sand out of a bucket or pouring the cereal out of a box— a lot like pouring water, right? In this physics science project, you will investigate how the size of granular materials affect how they flow.

Is that right side of your brain yearning to express its artistic side? This is a project that beautifully blends art with science. Learn about light and colorful shadows in these experiments where you mix and match various colors of light to create a mini light show and shadow wall. You might be surprised at the colorful hues you'll find lurking in the shadows.

The radiation sources recommended in this experiment are low-dose radioactive sources and do not require a license to purchase; they are safe to work with as long as these common-sense safety tips are followed:
Wear disposable gloves when handling any radioactive source.
Never rub your eyes or mouth while you are handling the radioactive source.
NEVER swallow any radioactive source and use protective glasses when bringing a source within a few inches of…

Ever wonder why it is harder to keep your balance with a heavy backpack on? Or why it is difficult to
make a toddler's sippy cup tip over? Maybe you are the kind of person who wonders about circus balancing acts and would like to learn how to ride a bike on a rope. Or perhaps you want to know how to make your toy car less prone to toppling over when racing through a sharp curve. In this science project you can learn about balance using marshmallows, skewers, and toothpicks. Sticky, yummy…

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Check out this page for more science projects related to this process.

MrBeast, the world's most famous YouTuber, has a series of challenge videos where he asks a contestant to protect some valuable prize - like a pile of money or an expensive car - from a series of attacks like explosions, giant fireballs launched from catapults, or even getting hit by a train! Contestants often have only 24 hours to build something to protect their prize, which presents a very interesting engineering challenge. Given limited time and access to materials, how can you best protect…

What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container

Balloons are a festive addition to many celebrations. You've probably noticed, though, that over a short period of time, helium-filled latex balloons start to lose their buoyancy. So when you're planning your next party, how soon can you buy the balloons in advance before they start deflating? In this science fair project, you will use a simple scale to measure the lift supplied by a set of balloons, and determine the rate of lift decay.

Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Hundreds of engineers were involved in getting the James Webb Space Telescope (JWST) into space. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to, but already, JWST has delivered astounding deep space images that offer an unprecedented look at…
