Science Fair Project Idea
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. Read more

Science Fair Project Idea
Have you ever dreamed about becoming invisible? Or about making something else invisible, like the mess all over your room? Invisibility may sound like the stuff of science fiction (remember Star Trek's "Cloaking Device"?), but in reality, military vehicles, like planes and ships, can be made less observable, or even invisible, to different detection methods—like radar, sonar, or infrared sensors—by using stealth technology. In this engineering science fair project, you'll find out… Read more

Do you like winter sports like sledding or skiing? Check out this winter-themed engineering project to build your own miniature "ski lift." Use it to transport small objects from one place to another, just like a real ski lift transports skiers from the bottom of a mountain to the top. Read more

Science Fair Project Idea
Have you ever heard that two phone books with the pages interleaved are impossible to pull apart? This might seem crazy, right? It is not that hard to slide a sheet of paper off the top of a stack of paper. How much friction can there really be between sheets of paper? In this experiment, you will use pads of sticky notes instead of phone books. How much weight can they support when you interleave the pages? Do you think you will be able to pull them apart by hand? The results might surprise… Read more

Did you know that you can use magnets to build a train that floats above its tracks? In this project, you will also use magnets to make the train stop, preventing it from crashing into the end of the track. Will adding more magnets help the train stop sooner? Read more

Science Fair Project Idea
What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat! It works because of something called centripetal force and it does much more than make a great roller coaster. It keeps a satellite in orbit and you in your bicycle seat during a turn. How does it work? Read more

Science Fair Project Idea
The first man-made satellite, the Sputnik 1, was launched in 1957. As of late 2020, more than 2,600 man-made satellites orbit Earth, with a little over 70% of them in low Earth orbit. If you would like to delve into how satellites and their sensors are configured, or into how their orbits are planned—and do not shy away from a little programming—this project is for you! With the help of FreeFlyer®—powerful software that allows you to simulate satellite orbit and… Read more

Science Fair Project Idea
Have you ever seen a magician float an object in the air? If so, you might think that levitation (making things float) is just a magic trick, but the truth is you can use an invisible physical force to levitate a magnet! Try this science project to find out how. Read more

Science Fair Project Idea
Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what the forensic expert does. In this science project you will be correlating the size of blood stains to the distance they fell, but do not get too grossed out. You will be doing it with fake blood. If you like figuring out mysteries, this is the science project for you! Read more

Safety Notes about Neodymium Magnets: Handle magnets carefully. Neodymium magnets (used in this science project) are strongly attracted and snap together quickly. Keep fingers and other body parts clear to avoid getting severely pinched. Keep magnets away from electronics. The strong magnetic fields of neodymium magnets can erase magnetic media like credit cards, magnetic I.D. cards, and video tapes. It can also damage electronics like TVs, VCRs, computer… Read more
