Sound: Bottle Organ
Blowing across the open mouth of a bottle causes the air inside the bottle to vibrate. The vibrating air produces sound. The pitch of the sound is determined by how fast the air vibrates. As the air inside the bottle decreases it vibrates faster and produces a higher pitched sound. You could write the relationship […]

Sound Craft: Wind Chimes
What is Sound? How is Sound Produced? Sound is a form of energy, just like electricity and light. Sound is produced when something, like a guitar string vibrates (moves back and forth) when strummed.

Sound: Blowing a Raspberry
Blowing a Raspberry means to make a sound by sticking out your tongue and blowing. The sound produced is much like the sound made by flatulence (farting). Sounds are made when something vibrates and air blown between your tongue and lips causes both to vibrate as seen in the video.

Things that vibrate send out sound waves. Characteristics of sound include, pitch, loudness, and quality. The pitch of a sound is how high or low a sound is. Pitch is basically your ears’ response to the frequency of a sound. Note: Original Art and more information found here: Mediacollege.com How Sound Works. Snagit and Snagit […]
