The span of this project was about two weeks. My group and I decided to create a guitar, flute, and drum. Our guitar was made out of a tennis racket. We tightened our strings in order to make different notes. The flute made out of PVC pipe made different notes based on how wide and far the holes are from the top of the flute. Holding fingers over the holes will also change the notes. The drum can make different notes and pitches based on where the drum was hit and with what material.
longitudinal waves- compression parallel waves, travel through medium transverse waves- travel through a vacuum, up and down wave length- measured from crest to crest frequency- measured by amount of vibrations in a set amount of time. amplitude- distance from the middle point to crest crest-the high points trough- the low points
omboucher- faster lip vibrations (or reed) leads to higher notes natural frequency- based on chemical composition, density, rigidity, shape, thickness, size, etc.
Reflection
Towards the end of our second semester, the pace of projects has increased drastically. We have lots of projects to finish by the end of the school year which made the "Build A Musical Band" project go so fast. Throughout this project I learned how to multitask while improving my attitude and demeanor skills. Since this project was so quick, my group and I faced many hardships. I multitasked by helping everyone in my group with at least one aspect of their instrument, but Lucy and I mainly worked on the guitar. The most difficult part of building our guitar was tuning the strings well enough to create the desired note. I improved my attitude during this hard task by always staying calm and positive. I need to improve my leadership skills for the next project because I felt as if I wasn't doing enough. Although I helped everyone with their instrument, I did not exactly have an instrument of my own. I was in charge of singing for our extra credit project using our instruments. I will also continue to improve my empathy skills throughout my years with STEM Marin.
