In the third unit of my junior STEAM class "Light, Sound, & Time," we spent the past couple of weeks learning about time.  We spent the first week learning about different ways people measured time. We learned about latitude and longitude, Foucault's pendulum, and arc length. We learned about the theory of general relativity, the twin paradox, and the concept of time travel. Our class met with Taylor Hoyt, a UChicago graduate who studied astrophysics. The class focused on the history of time-telling devices such as incense clocks, candle clocks, and hourglasses. My research helped inspire my own time-telling device called the Light Alarm. I was inspired by the simplicity of the physical design of modern alarm clocks. I was also inspired by sundials and how the device uses light to tell time. I took these qualities and created a unique way of telling time. Watch my video to learn more about my invention! In conclusion, I liked completing this unit. I had a fun time lea...

In unit two of my junior STEAM class "Light, Sound, & Time," we spent the past couple of weeks learning about sound.  We learned the anatomy of the human ear and how it perceives sound. We learned about the speed of sound, reflection and refraction, soundwaves, frequency, and wavelength. We learned about the Doppler effect and musical instruments. For our action project at the end of the unit, we had to make a one-string guitar or Diddley Bow out of common materials.  CH. "Diddley Bow." 2021. The Diddley Bow creates sound through the one guitar string. This guitar string is pulled tight between two nails that are mounted on a piece of wood. At one end of the string, there is a dead battery wedged underneath the string to create tension. The other end of the string runs through a soup can, this also creates tension. The tension allows the string to vibrate. The soup can then amplifies those vibrations the same way a soundhole does on a guitar. This creates the so...

This is an action project for my core class Light, Sound, & Time. In this first unit, we learned about light and how it works. I learned a lot about wave-particle duality, the visible spectrum, the electromagnetic spectrum, human eyes, and similar triangles. A couple of students went on an FE to the GCE building to use the darkroom that our teacher set up. For this project, we were asked to build our own pinhole camera to show how we could use light to capture images.  CH. "Pinhole Camera." 2021 I made a pinhole camera. The dimensions of my camera are 4.5 inches tall, 6.3 inches wide, and 8.4 inches long. The volume of my camera is 238.14 cubic inches. In order to capture a picture, the inside of the camera has to be completely black. When you close the camera, it has to be a completely light proof so that unnecessary light doesn’t mess with the picture. Once you place the light reactive paper inside and close the camera, you can not let any light in unless you are taking...
