Build a Physics or Music Experiment Tool Science Projects (15 results)

Build a device or tool to do a hands-on physics or music experiment. Create a device that will take measurements or one that moves, generates movement, or makes music as part of your experimental design.

Stealthy Shapes: How to Make an Aircraft Invisible to Radar
Science Fair Project Idea
Scientific Method
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
Try the Mythbusters' "Phone Book Friction" Experiment at Home
Science Fair Project Idea
Scientific Method
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
Using a Laser to Measure the Speed of Light in Gelatin
Science Fair Project Idea
Scientific Method
Think it takes expensive, sophisticated equipment to measure the speed of light? Think again! Outfit yourself with a simple handheld laser pointer, a protractor, and gelatin, and you're ready to get started. Read more
Making A Candy Waterfall: Can Solids Flow Like Liquids?
Science Fair Project Idea
Scientific Method
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
Use a Catapult to Storm Castle Walls
Science Fair Project Idea
Scientific Method
You may have seen movies or read books where armies in medieval times catapulted large rocks or other objects at castles (or each other!). These armies used different types of catapults to accomplish different goals — for example, launching things over or into castle walls to knock them down. In this experiment, you will use a ping-pong ball catapult to lay siege to a "castle" and find the right settings to hit your targets. Read more
Take a Musical Step Back in Time: Make Your Own Phonograph from Everyday Items
Science Fair Project Idea
Scientific Method
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
Measuring the Surface Tension of Water
Science Fair Project Idea
Scientific Method
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. Read more
Frequency-Dependent Sound Absorption
Science Fair Project Idea
Scientific Method
Want to start a garage band, but Mom or Dad won't let you because it will make too much noise? This is a good project for someone who is interested in acoustics and likes to build things. Who knows, it might help you figure out how to make everyone happy. Read more
High-Speed Magnets: Exploring Faraday's Law and Lenz's Law
Science Fair Project Idea
Scientific Method
Safety Notes about Neodymium Magnets: Neodymium magnets are very strong. Adult supervision is recommended when using them. Be careful not to drop the magnets, and do not let them slam together or fall. They may pinch your fingers, crack, or shatter. Keep magnets away from small children, pets, credit cards, and pacemakers. In the Science Buddies project Human-Powered Energy, you can learn about the basics of magnetic induction, or how moving magnets can be used to generate an… Read more
Distance and Constant Acceleration
Science Fair Project Idea
Scientific Method
Have you ever dropped something and wondered how fast it was moving while falling? If it was something fragile, like a cell phone, you might not have been thinking about this at the time — you may have been too busy trying to grab the phone! But you probably wanted to find out just how hard it hit the ground afterwards. We know that gravity forces an object to fall, but how does this affect how quickly something falls and how hard it hits the ground? For example, did the phone move faster… Read more
