Science Fair Project Idea
thumbnail So, you've got your popcorn and are settled into your seat at the movie. The lights dim—it's show time! But wait a second. Did you ever wonder how those lights dim so smoothly? It just wouldn't be the same if the lights suddenly snapped off, would it? In this electronics science fair project, you'll investigate dimmer switches, and even build a simple model of one. Try this project and light up your room, and your mind! 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

thumbnail We use passwords every day for our email and other computer accounts. How secure is the password that you use? How hard would it be for someone to guess your password? How hard is it to write a computer program to guess a password? You can see for yourself by writing a simple password guesser in the computer language Python. We will get you started with some ideas, a little sample code, and a few passwords for your computer program to try and guess. Read more

Science Fair Project Idea
thumbnail The banjo's roots trace all the way over to Africa. The unique sound that a banjo makes depends, in part, on the resonator. The purpose of the resonator is to amplify and project the sound that is made by strumming and plucking the strings. In this music science fair project, you will experiment with a resonator on a banjo and see if you can hear the difference in sound. Read more

thumbnail Do you live someplace where you get to experience the full glory of all four seasons? If so, you know well the heady blossoms and dramatic skies of spring; the long, sun-drenched days of summer; the trees shaking in crimson and gold in fall; and the sparkling, brittle snows of winter. But you might not know why we have these seasons, over and over again, in a cycle as predictable as the rising and setting of the Sun. The reasons for the seasons are surprising and have to do with Earth's tilt… Read more

thumbnail Ok, well you will not be making real monkeys fly, so what is this science project all about? You might think that flying, screaming monkeys and science project do not belong in the same sentence, but you will be working with toy monkeys, and toys can sometimes be great tools for exploring science. In this science project, you will launch flying, screaming toy monkeys and determine how far they fly with the stretch of a rubber band. The distance they will go can be graphed to see how distance… Read more

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 Everyone's used to the idea that people are either right-handed or left-handed for particular tasks. That is, one hand is preferred (or dominant) over the other for a particular task. Did you know that people also have a dominant eye? This project is designed to look for consequences of having the dominant hand and eye on the same side of the body (uncrossed) vs. having the dominant hand and eye on opposite sides of the body (crossed).

thumbnail Did you know that your guitar has a secret? Yes, that's right—hidden along each string are special places where you can play harmonics and make your guitar sound like a bell! In this music science fair project, you'll find out where the main harmonics are located on a guitar, and then see how those locations are related to the length of the strings. So get out your guitar—it's time to ring in a science fair project! Read more
