Build a Band
Waves Unit
The project of focus for our waves unit was called "Build a Band." In this project we used our newly aquired knowledge of sound waves to create 3 instruments capable of playing a full octave of notes. We were required to create a string, wind and chime instrument. At the begining of the unit we focused on the different types of waves, including conparing tanverse and longitudinal waves, as well as learning about light and sound waves. The topic of sound waves transitioned us into our "Build a band" project. We started the construction of instruments, keeping in mine the information we had learned about sound waves. Our group made a 2 string ukulele, a xylophone, and a recorder. Each of our group members divided the instruments so that each of us focused on one primarily. I was mainly in charge of the chime instrument, or xylophone. The basis of our designs were the initial blueprints that we created. However when we began construction some aspects had to be modified in order to create the best possible functioning instrument.
Content
Frequency (f): number of waves (or vibrations) created or recieved per second. The equation is f=v/λ. The unit is Hertz, Hz.
Wavelength (λ): distance of one wave from crest to crest. The equation is λ=v/f. The unit is meters, m.
Wave Speed (v): how fast a wave moves. The equation is v=λf. The unit is meters/second, m/s.
Amplitude: height or magnitude or intensity of a wave.
Transverse wave: Displacement of the medium is perpendicular to the direction of propagation of the wave
Longitudinal wave: Displacement of the medium is parallel to the direction of propagation of the wave.
Electromagnetic Spectrum: the range of wavelengths or frequencies over which electromagnetic radiation extends.

I feel like I worked very well during this project. The information we were learning was complex at times but once I understood, helped me greatly during the project portion of this unit. My team worked fairly well together and I somewhat enjoyed the challenge of working with people who I wouldn't normally be compatible with. One aspect that was my goal for this project was to improve on my "Risk-taking." I confidently believe that I acomplished that during this unit. I feel like I took risks when it came to the building and group parts of the "Build a band" project. I used more tools and built more things hands on then I normally do. When it came to the construction portions I usually let the more experienced group members do the things I wasn't comfortable doing for myself. This time around, I was determined to take more risks and I did just that in my building process. I also took risks in the leadership area as well. I tried my best to contribute more ideas and take advantage of any leading role oppurtunities. Somethings I feel like I could improve on were time management and being able to adjust better when things don't go my way. Time management is typically a strong suit of mine, that may a slipped away from me given my focus on my other goals. Another thing I want to continue and improve is being able to adhjust better when things don't work out. One way this can be acheived is by having a back up plan ready in case something doesn't go according to plan.
