How Do We Make Sounds from Pipes
Last month we learned that sounds are made from a series of vibrations. By touching our throat while we speak or sing we can feel vibrations. And what better way to study more about sounds than make a musical instrument–a pipe.
Using straws of different sizes, a polymer clay, and origami papers the kids were able to make their very own colorful pipes. As they started playing along with it their curious minds started asking questions.
“Eh! How do we make sounds from pipes?”
One kid also asks “Ah! Why do longer pipes create low and deep tones while smaller pipes create sharper and higher tones?”
The key to these questions is the word frequency which is a series of vibrations that travels inside the pipe at a given point in time. The higher the frequency the louder and sharper the sound being produced and vice versa.
And the children goes “Aaah!”
