# Build A Band

## Evidence Of Work:

For this project my group, Rose Hayes, Tyler McDonagh, and I were challenged to build our own instruments to demonstrate sound waves. We were required to design and build a band of at least three instruments with which we could play a song. The instruments had to all be able to play the notes A, B, C, D, E, F, and G. One of our instruments must use strings, one must use air movement (like a brass or woodwind-style instrument), and one must use chimes or something that you hit to make vibrations and noise.

Our group decided that it would be best that we divided the work evenly and we each tackled an instrument to work on and build. Rose made our flute and helped Tyler on the chimes, I decided to work on the string instrument which I built in the course of 4 building days in the makers-space with extra workdays in the classroom. We all started with making blueprints and collecting materials for our instruments. Rose and Tyler started with the chimes and recorder and finished them in the first 4 days of building and finalized them so that they looked professional and well crafted. I started with the base of our string instrument, which we decided would be a ukulele. I used balsa wood and cardboard for the sound box and shaped it into a traditional string instrument body. I continued on with carving the neck and attaching it to the base. Then, I put tuning pegs and strings to finalize the initial build. I had multiple issues here, mostly because the body was too fragile to support the tension that the strings were creating.

Regardless of the challenges I faced, I created a ukulele that had a lot of effort put into it and it came out looking well-made.

## Content:

1. Frequency- is the number of waves created or received per second and is measured in Hertz. This concept can be calculated by dividing the wave speed of a sound by its wavelength.
2. Wavelength- Each wave has a specific distance from its crest to another crest, giving this term the name wave length. Measured in meters, a wavelength is calculated by dividing the wave speed of a note by its frequency.
3. Wave Speed- Measured in meters per second, a sound's wave speed is how fast a wave travels and is found by multiplying the wavelength and frequency.
4. Amplitude- The distance from a wave's equilibrium to its maximum height or depth, its dimensions are labelled in meters.
5. Transverse wave- The movement of particles perpendicular to wave motion. These kind of waves contain crests and troughs and do not need to go through any kind of medium. Light and all types of radiation on the electromagnetic spectrum are transverse waves.
6. Longitudinal wave- Particles that move in the same direction as a wave motion are longitudinal waves like sound. This type of wave compresses and refracts, and they require a medium to function.
7. Electromagnetic Spectrum- A range of waves that are considered to be electromagnetic radiation, including radio, microwave, infrared, visible light, ultraviolet, x- ray, and gamma ray waves.

## Reflection:

Throughout this project our group worked really well together, we communicated well and all collaborated. We each managed tasks that would improve our project. The only issue that we might have faced too often was getting distracted and being off task. Regardless, we still finished our project in a respectful time, with astonishing results considering the problems that surfaced with some of our instruments.

I definitely improved on my risk taking and it helped me improve on a lot of other skills, like time management and daily goal setting. I challenged myself to take on one of the harder instruments which also helped me improve on my critical thinking and problem solving skills. I learned to find new ways to improve my work so that it could be the best of my work. On our next project I will make sure to keep working on these skills so that I can always show my best work to my peers and teachers. Overall, I enjoyed working on this project as it was a very positive experience for me.
