Build a Band

Giselle, Grace, Eryn

Description:

In this project, we had groups of 3 or 4, but my group had 3 people. I worked with Grace and Eryn for this project, lasting for about 2 weeks. We created 3 instruments, each of us being assigned to build one. I built a ukulele, Grace made a flute, and Eryn created a chime. Our instruments were built completely from scratch, using materials from the Makerspace. The ukulele was build from wood and fishing line. The flute was a PVC pipe, and the chime was made from wood and metal pipes. We created a video, where each of us can be heard playing our instruments to the tune of "Mary had a Little Lamb."  We also made a Google Doc explaining more in depth how each instrument works, which can be seen below.

Content:

Frequency (f = v/λ): Number of vibrations (waves) per second

Wavelength (λ = v/f): The distance from one point in a wave to the same exact point in the next consecutive wave (crest to crest, trough to trough, etc.)

Wave Speed (v = λf): Velocity of the wave (how fast it is travelling)

Amplitude (intensity ~ A²): Distance from the midpoint to the max of wave

Period (T = 1/f): Time required to make one wave (or per vibration cycle) 

Transverse Wave: Particle motion perpendicular to direction of energy/wave motion (ex. ocean waves, light); these are usually waves that travel up and down and carry energy

Longitudinal Wave: Particles compress and rarefy as wave energy moves along (parallel particle motion); these are usually waves that travel back and forth and carry sound

Electromagnetic Spectrum: The range of different types of waves along with the amount of energy they can transfer

Doppler Effect: Wave frequency increases coming closer, while it decreases as it's moving away

Reflection:

I think I did well in collaboration. My group really worked well together, and we helped each other when we struggled. I also think I did well in communication. My group was really easy to talk to, and I think part of the reason was because we were the smallest group, with only 3 people instead of 4. I was able to tell my group mates when I needed help, and tried my best to help them as well.

Something I think I could have done better in was critical thinking. I think I could have better planned how I was going to build the ukulele before actually doing it. It would have turned out a lot better if I knew exactly what materials I was going to use to make it before going right in and attempting to build it.
