What is a Rube Goldberg machine?
A Rube Goldberg machine is a contraption, invention, device that is over- engineered to to perform a simple task into complicated fashion.We first started thinking of ideas and completed a nice drawn blueprint. We needed to have 5 of the 6 simple machines in our project, and we used an inclined plane, screw, wheel and axle, pulley, and a wedge. We needed to have 10 steps with 4 energy transfers. Our theme was a bakery, and our end result for this machine was spreading bread on butter. We spent 3-4 weeks collaborating and making our project.

Force: Force is a push or pull on an object. You can calculate it by using mass times acceleration.
Mechanical Advantage: Mechanical Advantage is how much a tool makes something and how much further you have to push.
Velocity: Velocity is the rate of distance covered in a direction.
Acceleration: Acceleration is the rate of change in velocity speeding up or slowing down
Potential Energy: When the ball hit the other ball that caused the ball to roll down the two tubes

Potential Energy: When the ball hit the other ball that caused the ball to roll down the two tubes
Step one: Ball rolls down screw
Step 2: Ball hits a cup and starts the first pulley, which pulls out the wedge
Step 3: Starts the first pulley
Step 4: Pulls out the wedge
Step 5: Ball rolls down the ramps in the "bakery"
Step 6: Rolls into a tube
Step 7: Hits the "dominos" and attracts another ball that's on top of the biggest domino
Step 8: Rolls down another tube and goes into the "oven"
Step 9: Hits another cup and attracts another pulley
Step 10: Rolls down two more tubes
Step 11: Spreads butter on bread

Reflection:
The project went very well! Everything was very firm, and very well screwed in, and everything was well organized. What we need to improve on is to plan things out more and to let our teammates know what we are doing until we actually do it. In my train of thought right now, I feel like I should of said my ideas more often, rather than taking the back seat and going along with what my team mates were suggesting. My other thought was that I didn't ask my group for help when I needed it. For example, with the calculations, I was totally lost, but I was too afraid to ask because I thought they would judge me for me not knowing how to do it. Otherwise, everything went very smooth, organization was good, communication was good, staying on task was our biggest one, and having fun with it and collaborating together! I felt like I was more comfortable with my team mates once I got to work in a group with each and one of them. I did well of encouraging my teammates and writing everything out, but I need to work on saying my own ideas, and just let my mind expand and think out of the box, instead of thinking of only certain things.
I worked on this project with Bryce Bernales, Joaquin Arellanes, and Henry Zang
