Many sports skills require quick reaction times: think of hitting a 95-mph fastball, returning a 100-mph tennis serve, or blocking a slapshot at the net in hockey. (The Experimental Procedure section below has one way to measure reaction time.) Is your right hand faster than your left? Can you improve your reaction time with practice? Do both hands improve if you only practice with one hand? Try relating your reaction time to real situations in your favorite sport. For example, calculate… Read more

Science Fair Project Idea
A concert piano. It's a beautiful instrument and a spectacular sight when it's all set up on stage. The first thing you may notice when you first look at a concert piano is the impressive-looking soundboard, that large board on the back of the piano that is tilted up at an angle. It is used for amplification. The sound board greatly increases the volume of sound coming from vibrations of the strings. The soundboard is positioned so that it gathers the sound vibrations coming from the strings… Read more

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 don't just jump when that hairy spider comes around the corner, you scream! In this music science fair project, you'll find out if happy, sad, scary, and action scenes in movies use music with the same qualities. Read more

How accurately can people identify the location of a sound source when blindfolded? Imagine the hemisphere of space that extends above your shoulders at arm's length. Divide that hemisphere up into regular sectors and test the ability of blindfolded test subjects to point to a remembered sound source. For example, you could use the beep from a timer held at each test location, and then have the test subject point to where they think the timer was located. Record the magnitude and direction of… Read more

Beats are a pattern of oscillating sound intensity (i.e., the volume of the pattern grows and fades with a regular cycle). They occur when two tones of almost equal frequency interfere. People can perceive beat frequencies below about 7 Hz. Figure out how to create sound files to play pure tones on your computer. Create files with a pure tone of one frequency in the left channel, and a pure tone of a different frequency in the right channel. Systematically explore different frequency… Read more

thumbnail When someone yells, "Think fast!" and throws you a ball, are you able to catch it? When the bell rings at the end of class, are you the first one out of your seat? Can you make it through a sudden hairpin turn in a video game without crashing? If so, then you likely have quick reaction times. In this science fair project, you'll look at reaction times (how fast people react to sensory events), and see if people who play video games have faster reaction times than those who do not.

Science Fair Project Idea
Does listening to classical music help or hinder concentration and performance on cognitive tasks? You'll need help from a teacher to design two short, age-appropriate worksheet tests for this experiment. The tests should be of equal difficulty. You'll also need the cooperation of several additional classroom teachers in order to test enough students (at least 50-100, see the Science Buddies resource: ). Half the students will take test A while listening to classical music and test B with no… Read more

If you like music and musical instruments, here is a project that might resonate with you! This is a fun experiment to investigate materials that could be used to build acoustic musical instruments. You can use a music box mechanism and a sound level meter to see which materials make the best soundboards. Read more

For centuries, beautiful bell towers, like the Leaning Tower of Pisa, have been the center of village life, announcing the time of day, the joy of weddings, and the sorrow of funerals. They were also used to call villagers to action in times of danger. Have you ever wondered, though, why people put the bells in towers? The bells are so heavy, why haul them all the way up to the top of tall towers? Why not just ring them on the ground? Putting bells up high does make for a dramatic visual… Read more
