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 humanities class, Policy, we finished our second unit, Executive. We have been learning more about the Supreme Court and the different wars that took place that dealt with America. An FE that we went to during this unit was a murder trial at the Criminal Court House. This FE was very eye opening to me because I want to become a lawyer, mostly a prosecutor. It was amazing watching the prosecutor ask questions that all dealt with each other but she asked them in ways that she knew that the witness would know the answer too because the defendant would try to object but the judge would let the witness answer the questions only if she had any knowledge about it, which she did. It was so inspirational but it made me think about how the prosector worded her questions because it made it easier for me to understand what was going on and she asked them in a way where the witness had to explain everything that was going on when he crime went down. For this AP, everyone had to choose a w...
In my workshop, Prove It or Lose It, we have been working on what combinations are and what the Pascals's Triangle is. We have been working on finding different ways to go from point A to point B. We learned about the equation on how to tell if the triangle equals each other. A combination is something that deals with letters or numbers, and you can find a different ways to mix the letters or numbers, so that each letter/ number ends up in a different place each time. For example, if we use the word CAT. I can make 6 different words from this 3 letter word. I figured this out because I used a math term called Factorials. Factorials are when you take a number and put an exclaimation mark next to it. That basically means that you are taking this numer and multiplying it by each number that is smaller than this number. For example, 9!= 9x8x7x6x5x4x3x2x1. This is what factorials and combinations looks like. This is an example of using a three letter word and using factorial...
In Poetic Justice, we have been working on political poems in class. When I write poems I like to rhyme because it sounds better to me. We went on FE's that really helped me write these poems. We talked about the different types of poems and how you can write them, and that helped me a lot. My poem is very interesting, especially since it has something to do with me. I love the way Hiu and Sharon helped the class write out our poems. We've done classroom feedback, and I felt that it wasn't as helpful because I feel like I could've received more feedback, but I didn't get that from my class or from the other students that are apart of this class. My poem is very touching and I hope that, you, the reader enjoys my poem. ------------------------------------------------------------------------------------------------------------------------------------- Being a color is now a bad thing Go listen to Dr. King’s “I have a dream” The huma...
