Rube Goldberg Project
During this project we first learned about rube goldberg machines and what you need or what needs to happen in order to consider it a rube goldberg machine. We then learned about the 6 simple machines. Finally we designed our rube goldberg machines and worked our satirical messages into them.
Reflection
The conservation of energy is how energy is conserved even when the energy changes direction or forms. This is extremely easy to see in the step where the pulley is activated. Energy transfer is when energy transfers from one form to another, for example when potential energy is turned into kinetic, or when chemical energy into heat. During the second step of my rube you can see potential energy into kinetic when the boards and cars trigger each other.
The six simple machines are the inclined plane, the wedge, the lever, the wheel and axle, the screw, and pulley. These make many modern day tasks much easier and many more complex machines are made up by many simple machines. The first step of my rube is a lever, the second is an inclined plane as well as a wedge which stops the boards. Both the boards as well as the car use wheels and axles. the next step employs a pulley to trigger the next step. the second to last step is a screw. I chose the mystery box as my challenge step. This works by making the marble travel back and forth down ramps inside of the box. The reason I chose to do the mystery box is because it fits with my satire and shows how political figures say they are doing something about climate change but then it goes behind closed doors and we never hear anything about it.
My number one takeaway from this project is that I really need to stay on top of my work and that when you fall behind it is a lot harder to get caught back up. My greatest challenge during this project was when I had to put school on hold during the final week of the project because I had a concussion. I overcame this challenge by working really hard when I could. I think my biggest strength/asset during this project is the fact that I enjoy building things and working with my hands. this made the process of actually building mu rube more enjoyable even tough I was catching up on it. I think it also made my final project turn out better as everything works well together.

Homemade Batteries
All batteries are made up of 3 main components, an anode, a cathode, and an electrolyte solution. Batteries work when electrons travel from the positively charged cathode through the electrolyte to the negatively charged anode. In the case of my lemon battery the copper penny is the cathode, which is positively charged and wants to give its electrons away. These electrons then travel through the lemon juice, which is the electrolyte, to the anode. My anode is a zinc galvanized nail which is negatively charged and attracts electrons.
E&M Devices: Electric Motor
My device is a brushless motor that runs on dc power. It is also an outrunner motor meaning that the outside of the motor is the part that carries the magnet and is the part that spins. My device works when small bursts of electricity are sent through the coils. Different coils momentarily magnetize them and attract the magnets that are on the outside.
