The Science of Sound

Students in 6th grade have been learning all about the science of sound. It may seem simple to think that a piano, a trumpet or even the human voice are just different sounds, but what the 6th graders are finding out is the reasons behind those sounds and that they are actually more complex than they originally thought.

The first thing we learned are the different vocabulary words that more accurately describe the different parts of sound (particle vibrations) and what their jobs are. We learned about frequency (high/low) and amplitude (loud/soft) first as this is the simplest way to break down a sound wave. Then we learned about decibels (a way to measure amplitude) and hertz (a way to measure frequency) to fill in the blanks of how scientists can figure out the specific measurements in a wave.
The children seem to be incredibly fascinated by this and continue to learn a lot of information on how and why things make different sounds (timbres) in a very exciting way. Their next steps are to complete a series of science experiments to see/hear how these different vocabulary words come into play. Below is a picture of one of the experiment tubs...I can’t wait until they get started and see what they find out!
