The New and Improved Contact... THE TIMETACT

This unit for LST,my class explored time, if time is even real, how to view time and how to measure time. I learned that one of the first ways people used to measure time was the sundial. The sundial measures time with the sun and casts a shadow from a stick. Whichever angle that shadow is casting, you add an hour for every 15 degrees. For our field experience, my class went to the Planetarium to get a better understanding of light and how the universe displays that. The purpose of this Action Project is to create a unique time telling device that is inspired from the ones we looked at in class.

My idea for a new time-telling device is contact lenses that display time 24/7. The time will be embedded during the process of getting your prescription at the eye doctor. It will be a contact where the time will be displayed inside the prescription. The units will be second, minutes and hours, just like any other modern clock, but it will not be a clock more just a display for time. The contact that tells time is related to light because it attaches to the eye. In order for the eye to work, the pupil lets light in and when a contact is put on top of the eye light is going through contact and then the eye.The contact is effective because you will always be able to keep track of time, there is no way right now to always be on track of time 24/7.It prevents people from being late because the person will know always know what time it is.

Tuning my Diddley Bow

Diddley Bow,(LD),2017

This unit in Light, Sound and Time, we studied and explored what sound is. Sound are the vibrations traveling through mediums then into our ears. We dove deeper into frequency and wavelengths and how the pitch of a sound affects the wavelength and frequency. I also learned that the speed of sound is 343 meters per second and travels differently depending on the density of the object. My class visited the Chicago Hearing Society, an organization that helps people hard of hearing or deaf for one of our Field Experiences. We listened and asked questions to some of the volunteers that were deaf, I learned how to say thank you and you’re welcome in American Sign Language (ASL).

For this Action Project, we had to create a Diddley bow, something similar to a guitar. We had to create it with wooden sticks, tin cans, nails and batteries. This project was fun and interesting to do, to know more about it keep reading below.

Diddley Bow Diagram, (LD),2017,Befunky

To create the Diddley bow I had to gather, nails, strings, a tin can, a wooden stick, and a glue stick. Then I created a hole at the back of the tin can, then put the tin can down sideways on the wooden stick. To stabilize the tin can, I nailed two nails front and back, then I inserted a string through the tin can tying it from the front nail. Then I nailed a nail in the back of the tin can, pulled the strings as tight as possible around that nail and then inserted the glue stick for tension. Finally, I plucked the string and it created a guitar-like note. The Diddley bow and guitar make sound similarly, first one has to pluck a string then the vibration travels through the body then into the tin can, amplifying the sound, allowing people to hear the note. The thickness of the string is 1.3cm and length is 12cm.

Frequency and Wavelengths,( LD),Google Drawing, 2017

This diagram explains the vibration, frequencies and wavelengths of my Diddley Bow at certain points of the string. Frequency is the number of complete cycles per second, in the case it is vibrations per second, and is measured in hertz. Wavelength is the distance from one peak to the next and can be thought of as one complete wave cycle.

Peep Inside My Pinhole Camera

This unit is about light, sound and time, discovering what each means and how they all work together on earth. We explored our eyes,and looked into what parts make up a camera and eye..This was one of my favorite units this school year because I got to learn so much about light. I learned about why we see colors the way we do, which is because the colors of the spectrum are being absorbed and the color you are seeing in that object is the only color reflecting off of it.

This action project, we had to create a pinhole camera and take pictures with it in a darkroom. I had to use a cardboard box, then had to paint it black inside then create a pinhole to create the camera effect. 

I am most proud of myself for learning such interesting things and understanding all of it in such a little time frame.The pinhole camera captures light through the tiny hole that I created with a tac. It allows the light to pass through, working like a lens and projecting an object on the other side. The pinhole doesn't use refraction, the bending of light or reflection, the reflection of light. Reflection is light bouncing objects, and refraction is light slowing down and changing angle from one medium to another. The inside of the camera is black because the color black absorbs light while white reflects. If it were white the light would reflect the image making the light bounce around consistently, not creating an image. The black is perfect because it absorbs light while keeping the light in. A Pinhole camera works like any camera and functions like an eye: the image is flipped so it comes out the right side up,it absorbs the light then the pupil gets bigger or smaller depending on how much light there is, then light is focused by lens then directed onto the retina that sends signals to optic nerve. The pinhole camera is similar but is a simpler version of that.

The image didn't come out that well, it shows the background but not the elements of the objects.This could've been because of my own errors, such as: letting light in beforehand, not thoroughly painting the entire box black and having the shutter speed be too short or too long.

Height of object: 10 in

To create my pinhole camera I had to select a box and paint the inside black. After i painted the entire box black, I got a piece of metal and created a tiny hole so light could pass through. After that I created a shutter that wouldn't allow light to go through to ruin my picture. Actually taking the image with the camera was pretty easy, I set up my picture by putting objects together,then placing my pinhole camera a few inches away. The shutter speed (how long the pinhole let light through without the shutter) was around 1 minute. Then I closed the pinhole and got the film processed and developed. My class visited the Latin School and talked to a photography teacher, there, she taught us how to use a darkroom. First, we set up the picture with some of the objects she had in a box. Then, I sat down my pinhole camera next to the object for a minute,after that I went into the darkroom to process the photo.

If I could redo this action project,I would make sure I painted the entire box black and had more time to take more pictures with my pinhole camera.
