FK Action Project For Light, Sound, & Time Unit#1 "Drysol Barely Turned Out At all"

-


Hello reader,

This is my action project for Light, Sound, & Time unit 1. During this unit we learned about light: what light is, how light is preceived, how light works, and how eyes work. For this action project I created a pinhole camera. A pinhole camera is box painted pitch black with a small hole and a lens cover. I then put photo paper inside that box to create a camera. I then used the trigonometey concepts I learned in this unit.



A pinhole camera captures light through the aluminum lens and then the cap seals it off so that the inside is completely pitch black which then captures the image in front of the lens which then hits the paper. My camera illustrates the ideas of o because the light shines through the hole onto the paper that projects the image in black and white.   Most would believe that is reflection but it is not, reflection is when light bounces from one median to another. Projection is when light is displayed on a new median. The paper is very sensitive to light so the inside of the camera is painted all black so no light gets in unless the lens is open. I decided to take a picture of my hand sweat medication. Unfortunately it can not display color. The color spectrum is a actually a really interesting concept I learned in this unit. The visable color spectrum is a spectrum of colors that eyes can see. These colors are in between UV and infrared waves. Red being the closest to infrared (lower frequency) and purple being closest to UV (higher frequency). 







The Image I Took With My Camera:

The Math:





This is the diagram of what is actually happening with the light, The reflects off the Drysol bottle then enters the small lens witch then projects the light on to the photo paper displaying the image upside down. This diagram shows the angle of light hitting the pinhole, the angle of the image from the ground, the height of the Drysol bottle, the the distance between the pinhole and the image, the distance from the Drysol bottle to the image, and the distance from the Drysol bottle to the camera.


I really put a lot of work into building my camera. My image came out very……odd. I believe this to be due to the exposure time, perhaps I could have gone for 15 or even 20 minutes. It also could have been due to the small dent where my pinhole was.

The Manlet Bridge

-
Hello Reader, This was our 1st unit of Urban Planning called "Load". During this unit, we focused on truss bridges and their mathematical concepts, using only 75 popsicle sticks and glue to build bridges that could support 10 lbs and span a minimum of 18 inches. The bridge designs were completely up to us, and we were encouraged to be creative. This project mirrored the work of Mark Bennett, an urban planner for Chicago who has to work within resource constraints. Our efforts gave us better understanding of the dynamics of bridge engineering and how to apply mathematical concepts to our designs. Furthermore, we gained insight into the challenges faced by urban planners, who must successfully balance design creativity with material limitations engineering requirements. My bridge is called "The Manlet Bridge" because of it's size. The bridge that inspired the Manlet Bridge was the Somerset Bridge because it is the narrowest bridge at just 56cm wide. In order to ac...

Miguel's Bike

Hello reader! This is my action project for Design & Engineering unit 2. This unit I learned about the design process, gears, circles, ellipses, the ethics of design, gear ratios, and much more. This unit we went on a lot of great FE's but the FE to Dyson was really great in my opinion because we got to work WITH design not just have them talk to us then us doing nothing with it. Something I am very proud of this unit is my interview because I put a lot of work in to it. For this project I was given a persona to design a bike for based off the situation the person is in. The purpose of this project is to use all the information we have learned this unit on a real world problem being solved by others around the world but in our own GCE kind of way. Persona: Meet Miquel Location: Sitges, Spain Age: 12 Distance from school: 1.5 miles SITUATION Sitges is a small coastal town on the water, but it’s also full of tourists - meaning Miguel has to worry about vandalism when they lock ...

FK Action Project For "Food Class" Unit 3 "GMO's"

  GMO’s. Ok ok, before you think I’m some hippie who’s here to tell you how awful GMO’s are I’m actually here to tell you the opposite and i believe they are totally fine. But first some background info. I am a student at GCE lab school, this is my action project for my 3rd term of food class. During this class we discussed a man named Norman Borlaug. Norman Borlaug was an american scientist who introduced new, disease-free wheat to India and solved hunger there. Thanks to Norman Borlaug Morocco has much better yields of wheat.  During this class we also discussed probability for a little bit, and connecting it to Punnett squares. We also discussed plant reproduction, such as the parts of male and female plants like the stigma, and the stamen. We also went on a field experience to a farmers market and discussed different types of foods with the farmers and  had interesting conversations with them. It was also a blast having lunch with the class.  Now getting to the p...
