Physics of a flute:
The flute is made in the form of an open cylindrical air column. Its fundamental pitch is C and has about three octaves to C7. Sound is produced from a flute by blowing onto a sharp edge, causing air enclosed in a tube to vibrate. The modern flute was developed by Theobald Boehm who experimented with it from 1832 to 1847, desiring to give it a bigger tone. He finally produced a parabolic head joint attached to a cylindrical body with open-standing keys and finger pads to cover large finger holes. There are typically 16 holes. Since then, other minor improvements have been made. Wood or silver is most commonly used to get a more clear tone.
Physics of a rubber band guitar:
Plucking the rubber bands on the shoebox guitar causes them to vibrate. The vibration in turn produces sound. The pitch of the sound will vary depending on the thickness and length of the rubber band. In general, the thicker the rubber band, the lower the pitch and the longer the rubber band, the lower the pitch. This is because thick rubber bands have more mass than thin ones and the long rubber bands have more mass than the short ones. The higher the mass, the slower the rubber band will vibrate. Slow vibrations produce low pitches or frequencies, and fast vibrations produce high pitches or frequencies.
Physics of chimes:
Different lengths of metal pipe will produce different musical notes when struck at a specific point. A pipe that is an incorrect length will produce many tones, while a pipe that is the perfect length for that note will vibrate with on clear tone. Two or more pipes can be struck together to produce interference. Two pipes with slightly different lengths will produce obvious beats. A tuning fork held over a pipe will start it vibrating if the frequencies are matched showing resonance.`

Reflection: I thought that this was one of our lesser projects. My group was not as supportive and helpful as I would have liked them to be, leaving me having to deal with major problems. A few majors problems involved a substitute teacher breaking our ukulele, leaving us to resort to a rubber band guitar. Also, no one else in my group knew much about music so I had to spend most of my time explaining how instruments work. This set us back quit a bit. A few things that went well were that in the end we all ended up pulling through, and they tried their hardest to participate. I learned that next time I do a project like this, I need to research and better prepare myself so I know what I'm getting into.
