We started this project off by taking notes about wavelength. We learned about vibrations, different parts of a wave, and how different sounds are made. After that we read an article about specific instruments; chimes, wind, and string. Then we made charts calculating different wavelengths and frequencies compared to notes. After that, each group member made a blue print for their instrument with exact length and proportions. I was in charge of chimes. There is a picture of my blue print below. After perfecting our blue prints, we gathered the materials we needed, cut them to correct lengths, and started building. I was able to finish my chimes and help my group members with their instruments. We never got the chance to take pictures of our instruments or play a song because we went into quarantine for COVID- 19. That's why the only pictures I have are of my blue print. After in quarantine, my group and I face timed and came up with our song.
Frequency is the number of vibrations (or waves) per second in hertz (Hz). In physical models, this can be measured from compression to compression. The higher the wave speed, the lower the frequency will be. Wavelength and frequency are inversely proportional. Different notes have different frequencies. Chimes are based on the natural frequency of the material used. Every material has a different natural frequency that can be effected by the thickness or composition of the material. Frequency can also be found algebraically. The equation for frequency is f= v/𝝺.
Wavelength is the distance from crest to crest of one wave. Wavelength is measured in meters (m). Wavelength and frequency are inversely proportional. Wavelength can be found algebraically. The equation for wavelength is 𝝺= v/f.
Wave speed (velocity of a wave) is how fast a wave travels. Wave speed is measured in m/s. The algebraic equation for wave speed is v= 𝝺f. The lower the frequency, the higher the wave speed.
Amplitude is the distance from the mid line of the wave to the crest of the wave for a single wave. It can also be measured from the mid line of the wave to the trough of a wave.
Transverse waves are waves that move up and down vertically. Or, the movement of particles perpendicular to wave motion.
Energy transfer that moves horizontally. Or, the movement of particles in the same direction as the wave motion.
The range of wavelengths or frequencies over which electromagnetic radiation extends.
This project was a lot different than any other this year. My favorite part was definitely constructing my instrument because I was able to adapt to different plans and styles when things didn't go according to my plan. I think the thing I miss most is being around my friends. Despite being in quarantine and not being able to completely finish the project as we would have in the past, I still learned a lot and enjoyed the process. Two things I think I did well this project were being a conscientious learner and critical thinking. I did well being a conscientious learner because I was able to manage my time effectively throughout the quarantine and in school. I was also able to embrace challenges with an open mindset. I did this by not worrying about the opportunities I am missing out on because of COVID- 19, but taking it on with an open mindset and using this time to learn new skills and focus on school. I was also a critical thinker during this project because I was able to use evidence and reasoning to guide my decision making. I did this in the makers space while making my chimes. I was able to learn from my mistakes and adapt to new plans. Two things that I could have done better this project was communication and being a better collaborator. For communication, my group and I could have checked in with each other more often. One of my group members was totally lost on what to do for her instrument and we didn't have very good communication so it was a struggle. Whereas if we had just talked about it from the beginning we would have been fine. For collaboration, I feel like I could have helped engage my group in the project more while we were in school. However, I think we did a good job out of school. We were in contact and able to split the workloads fairly. Overall, I really enjoyed this projected and learned a lot of knew things,
