In my STEAM class, Light, Sound, and Time, we have been focusing on the vibrations that come from guitars. We visited Chicago Music Exchange for an FE, and we learned about the different guitars and why some cost much more then others. We learned about the guitar and how each part of the guitar does something to help produce sound. The guitar strings can be made with different materials, which would give the guitar a different pitch because each different material produces a different sound. It can also have a different pitch based off of the thickness, tension, and length of the string. For this AP, we made a Diddley Bow for our project. We had to bring in a can and battery and Adam gave us wood, screws, and guitar strings. Making the Diddley Bow was the hard part. I struggled with making sure that the guitar string was tight so that there could be a noise coming from the Diddley Bow. Adam helped me with making sure that the string was tight so that the instrument can produce sound. Down below you will see all of my measurements and pictures of my Diddley Bow. Enjoy!
Thickness of String: 0.04 in.
KRM, Measurements of Center of the Diddley Bow (2019)
These are the measurements that I found for my Diddley Bow and the angle that the string and wood have.
KRM, Harmonic Calculations (2019)
These are the 4 harmonics, with the wavelength of 1.471m and a frequency of 233.1 Hz. You find the wavelength by dividing 343 over the frequency of your harmonics.
343/frequency
343/233.1
= 1.471 (wavelength)
KRM, Labeled Diddley Bow (2019)
This is the Diddley Bow that I created. As you can see, I labeled each part of the Diddley Bow with another name because that is what each object is representing. The Diddley Bow makes its sound from vibration that resinates in the can when you pluck the string with your finger. It demonstrates the key science to our Internal Investigation because you can see the amplitude if you pull the string hard or soft. The wavelength of the string is in the middle on the Diddley Bow, so the nut to the string to the bridge (the whole in the middle of the can).
KRM, Harmonics (2019)
We had to mark the harmonics on our instrument because it shows where each harmonic is when the string is played.
KRM, Different Angle (2019)
KRM, Different Angle (2019)
These are other images of the Diddley Bow with different angles so that you can see everything that was done to the instrument for it to work.
Here is a video of my playing my instrument. Unfortunately, I was not able to use a tuner for different sounds so my Diddley Bow only plays one tune.
In conclusion, making the Diddley Bow was very fun and I enjoyed working on this AP. Adam helped me which was great because I could not put the nails through the wood. I hope that you were able to learn something new and I can't wait for what we are learning new unit. Thank you!
In my STEAM class, Urban Planning, we finished our second unit, Power, and we learned a lot about circuits and eco friendly home appliances. For this unit, we went to the Museum of Science and Industry to watch the Tesla coil be set off. That was a really cool experience because I wasn't expecting for the coil to be that loud. We have been studying circuits and how to make them. We learned about the different symbols that are used for circuits when you draw them out. For this AP, we were paired up with another person in our class and that made the process of this project better because there was a lot of work that had to be done for this AP. The format for this AP, was slideshow format. In our slideshow, you will see the circuit that we created, the eco friendly home appliances that each resistor is representing, calculations, and more. We had to talk about how this AP connected with SDG 7 and why we chose it. You will learn about the circuit that we designed and the home applianc
In my Humanities Class, Policy, we finished our last term of this class. I am so happy that I was able to take this class because I now know what I want to be in life because of this class. This class helped me realized that I willIn class, we have been learning a lot about the Supreme Court and the types of power that this court has. For this AP, we had to chose a certain case and talk about how that certain case was involved with this case. I learned so much from this case because the one that I chose actually deals with my life as a teenager in school. I chose slideshow format for this AP because they help me gather more information and I actually understand the work that I am doing. We visited the Veteran's Arts Museum and it was so interesting being able to see actual clothing and letters from important wars gives you a different look on it. Down below is my slideshow, hope you enjoy! In conclusion, I really enjoyed making this AP. Being able to learn about my rights
In my elective course called Global Peace, we have been focusing on the Gandhi principles and how people use these principles throughout their lives. For the AP, we had to type a 4-6 page paper about an activist that we chose, according to a list of activist that the teacher gave us. I chose Deray Mckesson to be the activist that I wrote my paper on. The process of this paper was very interesting and intense. I felt like I was going to struggle a lot with this paper because I was nervous. Sharon helped me by giving me corrections and helping me with the guide of the paper. Once I recieved all of the corrections from Sharon and applied them to my paper, that helped me a lot and I was able to continue to work on my paper. The rubric that Sharon gave the class was extremely helpful and that helped me with knowing exactly what to put on my paper because I was confused on what to talk about with the paper especially since it is a 4-6 page paper. Overall, the paper turned out fine and I fin
