Building homemade instruments
During the month of March, the STEM class made musical instruments (a stringed, chime,and a wind). My group was Kyle Jones and Jacob Jossart. We also looked at waves to figure out sound waves.
OUR INSTRUMENTS
Chimes: For our chimes, we used wood for our sides and cut wind chimes. How we figured out where we cut the chimes. In class, Mr.Williams said that chimes only fit a quarter of a wavelength. So we looked up the wavelengths of all the notes and then divided it by 4. Then we cut it to the length. That is how we made the notes in our chimes

Flute: For our flute, we also used a wind chime. So we basically used the above to figure out our notes. So we measured the flute, and we divide the whole length by 4 and poke a whole there. That is how we made the flute.
Guitar: For our guitar we used a different method to find our notes. There are 2 ways to change the frequencies of stringed instruments; shorten or lengthen our string, or change the thickness of our string. String instruments only make half a wave length so to figure out where to put frets on a guitar, we took the string measurement and divided it by 17.817 for our first fret.For our next fret, we subtracted the distance from our nut to the first fret and divided it by 17.817. We continued in this fashion until we got 7 notes. That is our guitar.
Concepts:
Wave speed: length X frequency
Period: 1/ frequency
Sound waves: waves created by an object to get a frequency
Compression: pushing together
Rarefaction: pulling apart
Medium: where a wave travels through
Amplitude: distance from midpoint of a wave to the crest of the wave
Crest: Top or bottom of the wave
wavelength: distance from crest to crest
transverse waves: vertical
Longitudinal Waves: Horizontal
Reflection:
This project could have been better in a couple of different ways. One way that it could have been better was that I should have done more of the work. Another way I could have done better was that I shouldn't have gotten distracted as easily. The last way I could have done better was to think before I do. Now with the good reflection. I did well on helping out with making the instruments. I also did good at taking good notes during the lectures. This could have been a better if I could have a better.
