Cans and Waves

Cans and Waves    

this was our sound unit. In this unit we learned all about how waves work in connection to sound and how to transport them. We went on an field experience to a guitar shop of our choosing. We dove into building our own diddley bows. We used this to learn about how to change the different parts of the wave. I understand waves a lot more now. I really enjoyed this unit and am proud of my action project.


How does your device produce sound? 
The vibrations of the string carry to the can and that amplifies it out to the surrounding area. The tin can focuses it on where it heads out to.
How do the various parts work?
The bridge works by keeping the string tight and away from the The body is the tin can and that allows the waves to bounce around inside and projects the waves out. This amplifies the sound.The string is what vibrates and sends the vibrations into the tin can. The board keeps everything steady.
How does it create different sounds? 
The different sounds are made by the length of the string which is done by pressing down on different parts. This shortens the length that will be vibrated and creates a higher pitch.

The length of the string determines the pitch. The vibrations that come out of the can are the sound waves. The wavelength is also based on how long the string is. The amplitude is the looseness of the string and the way the can raises the amplitude to make it louder.

Making a Space

Making a Space For this AP we focused on making our space usable for school and a place we would want to learn in. We discussed what defines a classroom. We took a field experience to Millenium Park to investigate what defines a classroom. As a school, we asked what it means to be a successful student and teacher at GCE. We discussed what we expect from ourselves and our teachers. The student body brainstormed the traits of a successful student and came up with a social contract for both the students and the teachers.   Social contract for students: We will work in a timely fashion. We will be curious. We will pay attention to the work, fellow students, and teachers. We will be encouraging. We will participate. We won't distract.   Social contract for teachers: We will accept feedback. We will be accommodating and flexible. We will be patient. We will have one on one time. We will be excited to teach! We will be understanding.   Both the student body and the teachers agre...

Sexism in the gaming community

sexism in the gaming community In this unit we looked a lot at history text books and what history means. We studied what does it mean to be a marginalized voice and what are the stories marginalized people have to share. We had many class discussions and read a case for reparation's. I learned about different ways people have privilege and different ways people may be marginalized. I never thought about class, ability, race and gender in such an open and honest manner before. I realized that things that seem like common knowledge to me aren't for everyone else and others do not know what I do and I don't know what others know.

Does Riot Fest belong in Douglass Park?

     This AP is for journalism. In this first term we learned about written reporting. We dissected what it means to be new literate and how we can discern what is real and what is fake. We talked with a journalist from the Chicago Tribune and learned a lot about responsible reporting. I enjoyed being able to think critically about what language is used and the meaning behind words. I found this term very interesting and I feel it has taught me how to be a better informed citizen. ------- Does Riot Fest belong in Douglass Park?      Riot fest took place from September 16th to 19th at North Lawndale's Douglass park. This was four days for music and festivities. Bands such as Morrissey, The Smashing Pumpkins, Slipknot, Rancid, And Machine Gun Kelly were playing. Surrounding Douglass Park are residential blocks. While Riot Fest is being set up the park is closed to residents. Residents are not able to walk their dogs in the park or play sports. Riot fest secti...
