Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

When stressed, do you prefer the fight or flight response? Scholars observe, measure, and identify the body's response to stress using a well-researched methodology. They learn about the autonomic nervous system, hormones, and more.

Did you know that your sense of hearing can determine texture? This Science Buddies science fair project has you experiment with four major eras in western music to determine the texture of the music. The Science Buddies project ideas...

Have you ever seen a great movie and then rushed out and bought its soundtrack? Did the soundtrack bring back the thrill of an action chase? Or the sadness one of the movie's characters felt? Music is a big part of the movie experience....

Music can be a great way to learn more about science. This project uses music to examine whether there is a correlation between age, gender, or musical background and being able to sing with perfect pitch.

Do you enjoy singing contests like American Idol? Well, male songbirds have their own version of a singing competition that has been going on for thousands of years, and classical musical composers have been taking notes. In this music...

This is a musical project about the resonance of closed-end air columns. Organ pipes, flutes, and brass instruments are examples of musical instruments of this type. In this project, you'll learn how the pitch of the note produced...

Systematically explore different frequency combinations in this experiment provided by Science Buddies. You will use your computer to create sound files to play pure tones on your computer, one frequency in the left channel, and another...

Students can easily create a musical whirligig to study sound production. These instruments are constructed out of everyday materials and allows students to use their imagination to make music.

Check out this fun science fair project about the physics of musical sound production. Here you will make musical instruments with drinking straws, one for each note on a one-octave major scale. You will figure out the right lengths for...

If you like music and musical instruments, this project might resonate with you. You will investigate materials that could be used to build acoustic musical instruments. You can then use a music box mechanism and a sound level meter to...

In this music science fair project, students will discover the locations of harmonics on an acoustic guitar and relate them to guitar string lengths.

In this project you'll learn how to make a piezoelectric pickup for acoustic guitar using inexpensive components. You can then connect your acoustic guitar to an amplifier, and record your own music. If you are interested in electronics...

This is a rockin' project for guitarists with an interest in the physics behind music. If you have ever wondered why the pitch of the note changes when you fret the string, this project will help you understand by applying basic...

Do you love to listen to your MP3 player while you're exercising, or listen to songs on the Internet? The relatively recent development of MP3 technology has made it possible to take a stack of CD's and store them on a device no bigger...

This challenge is to build a four-stringed musical instrument that can play a tune on different pitches.

Instructions to create a pan pipe made from straws. Also included is music to play songs using the pan pipe and a brief background about sound vibrations.

Cranked powered appliances and gadgets are becoming more and more prevalent. Items used in America such as flashlights and radios are one example. However, in third world countries, radios have many uses, some important and educational,...

Try this at-home science experiment to learn how plants make sounds.

An engineering design process project for students to create a regular rhythm of beats by spacing weights along a string and then dropping the string.

From the National Science and Technology Centre in Australia comes this easy experiment that shows how sound waves travel and what materials are good conductors of sound.

In this lesson plan students are able to manipulate sound to arrange a musical scale. Can be used by both science and music teachers.
