Project Description
For this project we had to make three musical instruments. One had to be a wind instrument, another a chime, and one string instrument. During this project we learned about frequency, wavelength, and other physics concepts pertaining to sound. We wrote a description of each of our instruments and a claim about how they work.
Claim and Reasoning
Here is the file that has our descriptions, claims, and reasoning about how our instruments work.

Physics Concepts
Wavelength- the distance from crest to crest or otherwise equilibrium to equilibrium of a wave
Frequency- the number of waves or vibrations in a unit of time
Amplitude- displacement from equilibrium to crest in a wave, amplitude affects volume
Transverse wave- a wave that moves up and down as it travels forward. These make up the electromagnetic spectrum.
Longitudinal Wave- compresses and expands as it moves forward. This makes up sound and requires a medium.

Reflection
For this project I think that my group worked very well together. One of the pits of this project was when we found out that our chimes were too high pitched to hear. This was pretty disappointing. This did help us to understand how we perceive sound. A peak of this project was when we built our wind instrument. It sounded very good, and was a big hit in the class. Another hard part of this was when we had to rebuild our string instrument because it was too quiet. On the new string instrument, we lengthened the strings. Another peak was when we were able to tune the string instrument to the proper tone. This took us a while, as the fishing line would slip from the screws and mess up the tuning.
