Homemade Battery Project
Summary:
The way this homemade battery works is by inserting metal screws into the each ice cube hole in the tray. Around the metal screws is a copper wire that is hooked to the tray. After all of the screws and copper wires are placed correctly you hook the positive terminal and the negative terminal to the end of the tray, which hooks up to the voltage meter. For the electrolyte I am using water to pour into the tray. |
Rube Goldberg & Satire Project
During this project we learned about the conservation of energy, mechanical energy, efficiency, power, and work. The goal of this project was to make Rube Goldberg Machine using six simple machines and one challenge step with a main goal/target. The six simple machines to include in our Rube Goldberg's were an inclined plane, a wedge, a lever, a wheel and axle, a screw, and a pully. The three challenge steps to choose from were the 720 degree spiral (which many people used as the screw), the 360 degree loop, and a time warp box. The goal for my Rube Goldberg Machine was for a cup (representing a cage) to drop on top of a little Lego man (representing our country).
Reflection Questions
Energy:
The conservation of energy is when energy cannot be made or destroyed but can be transferred or changed. In my Rube Goldberg you can see the conservation of energy throughout the whole Machine. Energy Transfer is when energy is processed or relocated to a different system. Energy is transferred from the pully to the inclined plane, then energy is transferred from the 720 spiral to the dominoes and the dominoes transfer energy all the way to the last pully that drops a cup over the Lego man.
Mechanics:
Simple Machines are simple mechanisms that are used to cause force to something that has an affect over a whole machine. For example, the six simple machines used in my Rube Goldberg all work together to have an affect on the same target (which is to force the cup at the end to fall down). All of theses steps in my Rube Goldberg are working towards the same goal. In my machine the simple steps used are the lever, the pully, the inclined plane, the screw, the wedge, and for the challenge step I chose the 720 degree spiral (which also counts as a screw). The way the challenge step works is a marble is dropped onto a spiral made of cardboard with only sides on the outside and the marble rolls down until it is dropped at the end continuing to cause different affects to the Rube Goldberg Machine.
Learning and Growth:
My number one take away from this project was if you are very creative really use your brain you can create anything using limited recourses. This is because at the beginning of this project I thought creating a Rube Goldberg out of items from home seemed nearly impossible especially when it came to including satire in the project. During this project my greatest challenge was getting the Rube Goldberg to flow all in one shot once the building was finished. I overcame this by making adjustments to different parts of the Rube Goldberg and testing it over and over again until it started to work. My greatest strength in this project was being able to go back and change parts of my Rube Goldberg and make refinements even when I felt like the Rube Goldberg Machine was already the best version it could be. When I was trying to take the video of the machine working there would be several different times when I had to retake the video and make adjustments to the machine. An overall strength I would say I used was perseverance because I didn't stop making videos until the machine worked in one try.

Water Reflections
What you are seeing is a picture of water from our pool reflecting against the ceiling and wall. The way this works is when the sun hits the pool, it reflects light rays that travel at an angle. This is what causes the light to reflect on the wall and ceiling across from the pool.

Project Reflection:
My greatest strength during this project was creating several different versions of my project plans before I made any final decisions. I did well when it came to coming up with many different ideas for what I could do for my project. I feel that another strength of mine during this project was communicating with Tina about where I was at and how I was doing during the project. Communication was key to this project for me because not being able to create any work in person was difficult in the first place, so making sure Tina and I were on the same page with my progress with the project made it easy to complete.
I would say that my greatest challenge during this project was trying to complete the project with little to no materials along with being away from home. Because of traveling purposes I didn’t have as many materials as I would at home to do this project but I eventually figured it out and was able to complete the project.
My number one takeaway from this project was just seeing the little things around you that have to do with physics. There are many things that are around me all the time that have to do with physics but I never would have noticed them or thought about it as much if we didn’t do the project. In my project I used a picture of the water reflections of our pool against the ceiling, this is not something I would have thought about if we were not doing the project.
The way I grew as “scientist” in this project was that I learned more about the way light works and how light affects everything around us.
I feel that I met all of the expectations and requirements for this project. I think I did everything I was supposed to and explained myself well.
