On the last day of class, December 6, 2005, Mrs. Anderson presented me, Glenn Bowie,
with two gifts: a large SQUIRT beverage bottle, and a thank-you note from class
members. She presented assistant teacher Tyler Knott with a case of four unopened
root beer bottles.
Mrs. Anderson commented that the Squirt bottle would have a note like that of a
tuba.
Analysis showed that the bottle note equals 105 Hz.
This picture is us in Dr. Bowie's class on sound.
During this picture we were howling like wolves to be able to compare our sounds with those of wolves
and an Alaskan Malamute.
We used a one program called WavePad to record sounds and another called Gram to analyze them.
We also made a jug band by filling beverage bottles with just enough water to get the right note. We were going to make a recording but we ran out of time.
In our jug band we had three different notes. The notes we used were F, middle C, and B-Flat, or A-sharp. We played Polly Wolly Doodle and I've Been Working On The Railroad.
The chart above shows the different frequencies for the notes in Hertz, or cycles per second. The human ear can hear between 20 and 20,000 Hz and most musical sounds are between 100 and 12,000.
This is a picture of Dr. Bowie, Mrs. Anderson, and Tyler Knott who put this class together.
