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.

Digging our self a better shovel

Digging our way into a better shovel Action project on tools In this Unit we learned about tools and empathy. We redesigned the shovel to make it easier to use for those who have a hard time with balance. We designed the tool for those with balance and joint issues. The elderly often have that problem. Empathy is about thinking of others' situations and trying to relate. This project really focused on those who may not have as good balance as I do. I got lucky with that and not everyone else has. It's important not to assume everyone can do what you can. This tool is a wedge and a lever. You use your hand as a fulcrum and your legs as the weight to wedge the blade into the soil.  As a class we tried planting flowers with and without tools in the garden. This allowed us to see how tools work and what they do. We interviewed a gardener so we could gather more information about tools. We went to Home Depot to look a their tools and try some out. It was very eyeopening...

Listening in the park

Field experience reflection We went to Millennium park as a school to listen to the Sonic Pavilion Festival. These were soundscapes in the Pritzker Pavilion. We ate lunch and then walked over to listen. It was our first field experience of this school year. I was very interested in what we heard. We were thinking about what makes a classroom and how we use the space and senses around us. I was very inspired by this field experience. I listened to two different soundscapes. The first one was Fulcrum by Kitundu. Before reading the program, I thought the soundscape he produced sounded like birds flapping their wings. This was really interesting to me because I have two pet birds. It also sounded like cars going by on a busy street and going over potholes. After I read the program I learned that Kitundu was inspired by birds. It was nice to know that I perceived what he intended. His execution reflected his inspiration. We were instructed to draw what the sounds made us feel. Since the so...

bodies and bills

Bodies and Bills Patricia Van Pelt, This bill is important because it creates a system that will hold non-transplant organ donation organizations accountable. The Non-Transplant Organ Donation Regulation Act is necessary. The fact that it isn’t already established is horrible but thank you for pushing for it. The lack of transparency in many organizations is appalling and this will help reverse that. When you lose someone it can be incredibly hard, especially when donating human remains. You need to know the organizations you are donating to are ethical and trustworthy. This bill prevents those organizations from taking advantage of grieving loved ones. In the next election, I will be able to vote and if you keep on advocating for this bill I will support you. This bill shows caring and respect towards the grieving and the desire for transparency in non-transplant organ donation organizations. This bill means that educators and many more can get access to organs/ human remains ethic...
