Science Fair Project Idea
Have you ever blown across a bottle's top and made a pleasant, resonant sound? If so, have you wondered how that note is made exactly? A bottle is actually what is called a closed-end air column. Clarinets and some organ pipes are examples of musical instruments of this type. In this science project, you will use bottles to investigate how the length of a closed-end air column affects the pitch of the note that it makes. All you need are some bottles, water, a ruler, and a chromatic tuner. Read more
Science Fair Project Idea
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
Science Fair Project Idea
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 and like playing acoustic guitar, this could be the perfect project for you. Read more
Science Fair Project Idea
The American holiday of Thanksgiving is a favorite of many. Friends and family getting together, a big feast, fancy china and glassware on the table. Who can resist the temptation to make the wine glasses sing? Find out more about how this works with this project! Read more
Science Fair Project Idea
Are there some songs that always make you feel sad when you hear them? How about "Scarborough Fair," George Gershwin's "Summertime," or the Beatles' "Eleanor Rigby"? All of these songs are in a minor key. Minor keys have more intervals, or halftones, than major keys do. Some musicologists (people who study music) maintain that minor-key songs are more likely to be perceived as sad, while major-key songs are more likely to be interpreted as happy. You can research the competing explanations… Read more
Science Fair Project Idea
This is a rockin' project for guitarists with an interest in the physics behind the music. Have you ever wondered why the pitch of the note changes when you fret the string? You can find out for yourself with this project on the fundamental physics of stringed instruments. Read more
Science Fair Project Idea
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
Science Fair Project Idea
The renowned pianist Vladimir Horowitz once said, "The most important thing is to transform the piano from a percussive instrument into a singing instrument." In this project, you will learn how you can make piano strings sing using sympathetic vibrations. Find out which notes make another one sing the longest by measuring their sound intensities using Google's Science Journal app. Read more
Science Fair Project Idea
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. It intensifies the emotions in scenes so that you do not just jump when that hairy spider comes around the corner, you scream! In this music science fair project, you will find out if happy, sad, scary, and action scenes in movies use music with the same… Read more
Science Fair Project Idea
Do you love to make music, but do not have access to all the instruments you would love to play? Check out this fun science fair project about the physics of musical sound production. You will make musical instruments with drinking straws, one for each note on a one-octave major scale. Can you figure out the right lengths for a series of straw "oboes" in order to play a musical scale? Read more
