Do It Better
Project description:
With this project we got a lot of freedom. Our instructions were to pick a project that we had previously done and make it better. We decided to redo our ukulele from the musical instrument project. We wanted to redo it with all wood instead of making the body out of cardboard. If we made it with wood the sound resonates better and makes the sound louder. We knew it would be tricky starting from scratch and having to carve out a new neck/body from wood.

Key Concepts
Doppler effect~when sound changes in frequencies because of movement of the sound relative to an object
Constructive Interference~when waves match up perfectly, making a bigger wave
Deconstructive Interference~cancel each other out (compression and rarefaction)
Refraction~one medium to another medium and bends direction
Wavelength~the distance from the top of one crest to the top of the next one(meters)
Amplitude~the distance from the mid-point to the crest of the wave
Frequency~how often a vibration occurs
Period~the time of a back and fourth swing(seconds)
Velocity(wave speed)~wave speed(wave length times frequency)
Hertz~the unit of frequency
Transverse Wave~motion at the right angles to the direction in which a wave travels
Longitudinal Wave~the particles move along the direction of the wave rather than it at right angles
Inference(constructive)~waves increase in amplitude
Inference(deconstructive)~the high part of one wave simply fills in the low parts of another
Nodes~in a standing wave certain parts of the rope, called nodes, remain stationary
Antinodes~the positions on a stationary wave with that largest amplitudes
Lens~piece of glass that bends light
Convergent~light rays come together
Divergent~light waves spread apart
Blue Shift~increase in frequency
Red shift~decrease in frequency

This project was really fun to do especially with the group I had, and it made it a good experience. First we found a piece of wood we could use as the neck, we had to use the power saw a bit, but we mostly had to carve to wood out ourselves with a chisel. Which can be very tiring. Carving out the neck toke up most of our time, also we didn't have the thin wood we were going to use for the body yet. Once we got the wood for the body we used the power saw to cut it into six pieces to then put together making a box. On one of the big sides which we would be using as the biggest top piece we drilled a hole through it. we had to use the chisel to make the circle more circular and then had to sand down the sides of the circle to finish it off.
Some peaks of this project were that our group was really fun to work with, and we did some good work. We knew what we had to so and then we completed our takes. Also I learned how to use a chisel, I knew what they were I just had never used one. Also my powers skills greatly increased. Some pits of this project were time management. We had only a little time to do a big project. Towards the end it got a little bit stressful knowing how much we needed to do a pretty short amount of time. I also felt like it was a little bit hard for me to get as involved as I normally do with projects because I don't have much experience with a ukulele. So some of the times the group members who had lots of experience with ukuleles would ask me to do something with the instrument and I wouldn't really know what they were talking about. I felt bad asking them to stop and explain to me what the vision was. Overall I feel like I learned a lot from this project about ukuleles that I didn't know before.
