Science Fair Project Idea
thumbnail Here is a riddle for you: name an instrument that you play with your hands but never actually touch. Have you guessed the answer? It is a theremin! This unusual instrument makes sound without anyone touching it. How does a theremin work? It has an antenna that can detect the player's hand nearby, and as they move their hand around the theremin, the sound it makes changes based on the hand's position. In this music science project, you will get to use your own mini theremin to investigate… Read more

thumbnail 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

thumbnail Don't you just love listening to music? In the 1980s, people listened to music on the Sony® Walkman®. Now, people listen to their favorite tunes on MP3 players and on their Apple® iPhonesTM. But listening to music on devices actually started in the late 1800s and early 1900s. In those days, people would gather around their phonograph to listen to their favorite tunes—people were just as amazed with the phonograph as you would be to handle an iPhone. In this physics science… Read more

thumbnail Did you know that your heart beats at different rates depending on what you're doing? The more physically active you are, the faster your heart beats. You can measure the rate your heart is beating by taking your pulse. This science fair project will show you how to take your pulse and help you investigate which daily activities get your heart beating the fastest. Read more

thumbnail How do you feel when you ride your bike into a strong wind? Do your legs feel like lead? How about when the wind is at your back? Does that make you feel ready for the Tour de France? In this science fair project, you will investigate how wind-powered devices, like pinwheels, also react in different ways to the direction of the wind. Read more

thumbnail So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this science fair project, you'll blow on different kinds of pinwheels with a blow-dryer and see how far away you can get before they stop spinning. This will give you clues about how sensitive the pinwheels are to wind, and why. So come spin your wheels and get… Read more

thumbnail Do you love roller coasters and other kinds of exciting rides? Are you a thrill-seeker? Well, this is the science fair project for you! What makes a ride so thrilling that people want to ride it over and over again even though it scares them? Is it the speed, the twists and turns, the vertical drops? In this science fair project, you will build and use an accelerometer to figure out what makes a roller-coaster ride worth standing in line for. Oh, and if Mom and Dad ask what an amusement park… Read more

Science Fair Project Idea
thumbnail The movement of satellites is intriguing, but how do they orbit the way they do? Aerospace engineers run calculations and set up computer models to help them predict how satellites move in space, but in this astronomy science project, you will create a physical model with marbles, clay, and a cookie sheet to help you study how satellites move in space and learn from your observations.

thumbnail Have you ever had a cut or a bloody nose that seemed like it would bleed forever? Though it might have seemed like a long time, it probably did stop pretty quickly. This is because different factors in a person's blood normally work together to plug the opening caused by the cut in a process called blood clotting or coagulation. However, some people have a genetic disorder called hemophilia that causes them to bleed excessively. If a person has hemophilia, he or she is usually missing some of… Read more

thumbnail Has your dog ever barked, seemingly for no reason at all? Or has your cat ever stopped and carefully smelled a spot that looked perfectly clean to you? Pets, like people, have senses that they use to learn about and to react to their world, but their senses can be stronger or weaker than people's. In this mammalian biology science fair project, you'll study your pet's sense of taste by conducting taste tests and watching how your pet acts to determine his or her favorite type, flavor, or brand… Read more
