MUSICAL INSTRUMENTS
In this project, my group was Eli Teel, Grace Olson, and Hana Ongwongsakul. Our prompt for this project was to make three kinds of instruments, chimes, winds, and strings, and make each instrument play A, B, C, D, E, F, G. We were given two to three weeks to create the instruments, write down how they work, write a song about physics concepts, and on the last day we presented. Here is what we came up with:
Concepts that we covered:
wave speed- (m/s) the speed that a wave travels through a medium. We used this to make the notes change the frequency, changing the pitch.
wave length- (m) the distance from one crest to the next one.
frequency- (Hz) how often a vibration occurs. We used this to change the note that our instruments played.
period- (s) time of a back and forth swing. We used this to keep the notes that we played at a consistant note.
amplitude- (m) size of the wave (controls the volume). We used this to make our instruments louder.
Reflection:
My group worked extremely well together. Part of the cause of this is because we are all really good friends. We all are also very worried about our grades, so we all worked hard the whole time. Two things that I feel like we did very well were time management and cooperation. We all worked hard, so we had time to perfect our instruments, and that made them sound very good. We also had enough time to be able to completely understand the concepts, which I have not been able do with every project. We also cooperated well together. Because we are all close friends, working together and making our ideas into one project made each instruments that much better. It also made the few weeks more fun, and that always makes the project go better.
Some things that my group could have improved on were no getting side tracked and always staying focused. Not all of my group was working at the same time. If we all worked all the time, we could have gotten that much more done in the same amount of time. We should have stayed focused throughout the process to make sure we got as much done as we could. I do think that we did all that would be expected of a ninth grade science project, and we did it successfully.
