Evidence of Work:
For about a month, we have been working on our Rube Goldberg project. It has been a very fun but complicated experience. A Rube Goldberg Machine is a machine that makes a simple task a lot more complex. For example, if the machine makes a balloon pop, then it will take many steps to get to that simple task. This makes things a lot more fun and interesting. We had to answer What is the most complex way we can complete a task using simple machines in the manner of Rube Goldberg? For this project we got 2 days to brainstorm and plan out our machine. We also got 9 days to actually build our machine. We had the last 4 days to practice our presentation. We decided to have a Hollywood theme for this project. The Hollywood sign and red carpet was included in our machine. We also had a “ferris wheel” to represent the Santa Monica pier. The hardest part of his machine was trying to get every step to work at the same time.

Content:
Force - The push or pull on an object. It is calculated but multiplying the mass ans the acceleration. There was force applied to the dominoes when the ball pushed them over.
Speed/Velocity - Speed is the amount of time a distance is covered and velocity is speed, but in a certain direction. Velocity is calculated by dividing the change in distance over the change in time. There was a certain velocity that the ball had when it rolled down the ramps.
Work - The amount of energy put into something. It is calculated by multiplying force and distance. There is work being done when the ball rolls down the ramp also.
Mechanical Advantage - How much easier a tool makes something. It is calculated by taking the force of the load and dividing that by the force of the effort.
Acceleration - The rate of change of velocity(How much is it slowing down or speeding up). It is calculated by taking the change in velocity and dividing that by the change in time.
Potential Energy - Energy an object has due to its position at a height or in a gravitational field. It is calculated by taking the mass, acceleration due to gravity(9.8 meters per seconds squared), the height, and multiplying them all together.
Kinetic Energy - The energy due to motion. It is calculated by taking the mass and velocity squared and dividing that in half or by 2.
Reflection:
My group and I did a good job on this project. We do have some things that we might need to work on. I feel like I got more comfortable with talking in front of other people and judges. I used filler words some of the time but I got better at that. I also improved on my leadership skills. I normally would wait for another person to give an idea or get us in the right direction. But when I was working on the machine, I helped with a lot more ideas and with giving the group a direction for the day. I still need to work on time management and multitasking. During the project, we had to do a lot of last minute things because we had bad time management. A lot of the time during our building days, two people were working on something while the other two were just watching not knowing what to do next. In my next project I am planning on continuously working hard on all four of these things that were a little hard for me to do.
