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!
This is the last term of my junior year in my STEAM class called "Urban Planning". We have been focusing on bridges during the first unit of Urban Planning called "Load". We looked at different types of bridges and we studied why some bridges are more stable than others. We also learned about the forces that act upon bridges and the different types of energy that is created. For this AP, we had to build a bridge with our partners out of toothpicks and we tested them with weights in the OC. This was a very fun process and I enjoyed watching how my classmates had different ideas for the same type of bridge. My partner and I put a lot of work into building our bridge and I am happy that we were able to work with each other without any problems. I hope you enjoy my project, Thank You! For the process, everyone received 60 popsicles sticks and Elmer's glue. We had to make the bridges so that they can hold up to 10 pounds. Our bridge was able to hold ...
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...
This is my last AP in my Humanites elective class called Global Peace. In this class we have been working on nonviolent acts that help with violent acts that are going on all around the world. We had to creat some type of challenge as our nonviolent act. I chose to do turns that most people can not do in the world. I will have people come and give away their clothes to drives that are taking clothes because there are people in this world that need the clothes more. We hade to write a paper with 500 words or more to explain what you are doing and how your act helps with the world and we also had to create a slideshow or video to show the challenge that we decided to take. I hope you enjoy my project and hopefully you want to give away clothes that you no longer need to people that really need these items in life. Paper Video In conlusion I enjoyed working on this AP and I hope that the rest of this year teached you something from my AP's.
