The Useless Box
In this project we were supposed to make an electromagnetic device. The device that I chose to make was a useless box. What this box does is when it turns on the box turns itself off. It does that by using a servo motor that is attached to a plastic finger, when turned on the servo motor moves the finger out of the box to turn the switch off. Then the servo motor moves the finger back to its original state, until it gets turned on again.
Homemade Battery Project
Lemon batteries work by creating a chemical reaction between zinc, copper, and electrolytes, such as those stored in the juice of a lemon or lime. By squeezing the lime it breaks up the juice filled cells within the flesh. The more damage that you do to the lime without breaking the skin the better the experiment will work.
Then when you pierce the shield of the lime with a nail. The nail goes through a process of oxidation and letting go of its electrons creating a cathode which, when run through the voltmeter, will become an anode. Because the nail is more negatively charged the electrons flow through the wire and the circuit into the penny or copper wire. Making the penny or copper wire have more positive charge, so when you connect the voltmeter will show the lime has a charge of 0.5 volts or more.

The Satire/Rube Goldberg Project
In this project we made a Rube Goldberg Machine (RGM) about something that we thought was important. What I chose was light conservation and that people don't conserve energy. How I chose to portray this in my RGM is to put my satire piece that we did in humanities on my shadow box and what my RGM was trying to accomplish was to turn on and off the light representing how people don't turn off their lights.
Energy:
The topic that I was trying to convey was conservation of energy. This is demonstrated in my Rube Goldberg when the light is turned on and off in my rube.What I'm trying to say when I do this in my rube is that when people turn their lights on they waste money and energy when that light doesn't have to be on. Energy transfer is when a force of energy is moving from potential energy to kinetic energy or the other way around. This happens in my rube when there's tension from the puck being held by the string which is potential energy and then it moves into kinetic energy when I cut the string in the pucks fall to start the rube.
Mechanics:
The simple machines are wheel, screw, incline plane, pulley, lever, wedge they are important because they represent a way to complete work in a simpler way. These six simple machines are represented in my Goldberg machine with different materials from a classroom and from random things in my house. An example of this is that my wedge is a pair of scissors, another example would be that one of my inclined planes is a piece of wood screwed into another piece of wood that is on the wall. In this project we were asked to use a challenge step in our Rube Goldberg Machine. Well I chose to do the shadow box or the time warp box. How I did this was I added a bunch of many inclined planes inside of a box and then it was connected to the piece of wood on the wall. The one thing that I had to include was that I had to be in there in the box for 10 seconds which was plenty long enough.
Learning and Growth:
I think that my number one take away from this project is that there are multiple different ways to interpret work and that is all around us. One of the greatest challenge for me was the time warp box, This was challenging for me because it was a lot of trial and error and I actually had to scrap my whole entire first design and make a new one. Because The ball didn't fall right or it fell out of the box and it was just a lot of trial and error. I think that the greatest strength of this project was the actual making of the rube. Why I think this is because building comes easily to me and I knew what I was doing so it was easy for me to finish it and make tiny tweaks to it to make it work correctly.
Digital Portfolio Update and Project Reflection
What we were asked to consider is reflection, waves, refraction, color, light waves, light emission and their relationship within a photograph. Some of the things we did in this project to explore this relationship was to make a camera obscura, a pinhole camera, look at gas through a spectrometer. We were asked to take a photo of each property of light.
We researched one of the brightest lights in the world, which is in Canada and is made by the extraction of photons from electrons. We were also asked to look at light as gas. Our study of light was pretty thorough.

My greatest strength in this project was the actual taking of photographs that conveyed the property of light we were trying to evaluate. As you can see in the above photograph I captured diffraction. “Diffraction is when light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands optical phenomenon.” The Free Dictionary, https://www.thefreedictionary.com/Defraction. As you can in the photo I show diffraction by the peach colored light in the middle being diffracted into multiple different colored lights by a special type of glasses called spectrometer glasses.
My greatest challenge in this project was the research. It is hard for me to research because it is difficult for me to focus on one thing at a time sometimes, especially if it is a topic that is not particularly interesting to me. I dealt with this challenge by procrastinating and then really trying to set my mind to it when under pressure. I work well under pressure, and I am not sure I will try to fix this part of me.

My number one takeaway from this project is that light is “cool” and there is way more to it than I knew, making it interesting. I learned that there is a light that is bright enough to allow better understanding of viruses. Through reflection of light (light displacement) scientists were able to make a 3D model of a SARS COVID 19 virus. Another challenge I had was with the pinhole camera - this turned out to be a very time consuming way to make a photo (5 hours to get one photo that showed anything). See photo above for photo - this was the best version of my work (unfortunately).
I grew as a scientist during this project by expanding my knowledge of light, learning the properties of light, and then experiencing these first hand. We really did a thorough study (analysis) of light and now I see the world differently - in a new light!
I feel I did well on this project - I took good photos and then analyzed them and their relationship to the properties of light. As you can see from the photos (my best work) I gained knowledge of the topic and made them into a reality.
