You are coming into the house after a game of flashlight tag with your friends, but the front porch light is not on for you to see the doorknob! What is going on? Maybe your parents know that turning a light on means moths will gather there, and they do not want you letting moths inside when you open the door. You have probably noticed how moths are attracted to lights at night. They will even fly dangerously close to flames in their journey toward light. In this project, you will learn a… Read more

Science Fair Project Idea
If you're like most people, you like listening to music. Have you ever wondered how your ears and your brain turn the sound waves out there in the world into the experience of music in your head? If you're interested in doing a project about how we hear, this is a good one for you. With this project, you'll do background research and make measurements to understand how the sensitivity of your own hearing varies with the pitch of the sound. Read more

Science Fair Project Idea
Have you ever wondered how a radio can grab signals that are transmitted through the air and convert them into sound? In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. Read more

- Less Details
Time Required Average (6-10 days)
Prerequisites To do this science project, you must live in an area where you can receive at least one strong AM radio station. You can check for this with a car or portable radio.
Material Availability Specific circuit items are required. A Science Buddies kit is available for your convenience. See the Materials and Equipment list for details
Cost Average ($40 - $80)
Safety Never operate your crystal radio during a thunderstorm. When not in use, always disconnect your antenna from the radio circuit, and connect it directly to the ground rod. Be sure to wear safety goggles when installing the ground rod, especially if you are using a metal hammer. An adult's help might be necessary for some steps in the Procedure.

This is a great project for a musician who is interested in the physics of stringed instruments. If you've ever played an acoustic guitar, you may have noticed that picking a single string can make one or more of the other (unpicked) strings vibrate. When this happens, it's called sympathetic vibration. What intervals lead to the strongest sympathetic vibrations? Find out for yourself with this project. Read more

Time Required Very Short (≤ 1 day)
Prerequisites To do this project, you will need a properly tuned acoustic guitar (or other acoustic stringed instrument). You'll need to know enough about playing the instrument to produce clear, ringing tones by picking (or plucking) the string while changing its effective length by fretting (or fingering) it.

In this project, you'll investigate the physics of standing waves on guitar strings. You'll learn about the different modes (i.e., patterns) of vibration that can be produced on a string, and you'll figure out how to produce the various modes by lightly touching the string at just the right place while you pick the string. This technique is called playing harmonics on the string. By the way, we chose a guitar for this project, but you can do the experiments using any stringed instrument, with… Read more

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs. Read more
