    Analysis:
    Unfortunately, my machine was very close to working, but was not able to complete the task of turning the calculator on. I gave it five tries and each try my machine would work all the way up until the last step, but could never complete that last step. When I was creating this project, I knew I would have difficulty with it as some point. All of my supplies were recycled materials except for the marbles and dominoes, and with that being said I had to make the most out of these materials. My second step in the machine involved a seesaw that I created with old popsicle sticks. During the process of creating my machine, this was the step that I had the most trouble with. However, while presenting my machine, this step surprisingly worked every time. My final step that included the bouncy ball going through the toilet paper tube and onto the on button of the calculator is what gave me issues. Before I began my five trials, I attempted my machine to see if there was anything I could fix. I noticed this issue while testing it, and attempted to fix it by removing the toilet paper tube and placing a golf ball onto the calculator's on button so the bouncy ball could fall off the ramp, hit the golf ball, and turn on the calculator. The step worked in theory, but when it got down to my trials, the marbles that hit the bouncy ball to get the bouncy ball to move were not hitting it with enough force causing the machine to stop there. With a little aid from me on that one step, the machine worked. All in all, I am very proud of my machine. With using recycled materials comes a lot of difficulties and doing the project solo can also make building my machine a little more harder to do. I believe that if I had had more guidance and more time, my machine could have worked. It has the potential to work now, but a few adjustments here and there could make all the difference.

    In my Advanced Science class, our first project was to create a Rube Goldberg project in which the end result will turn on a calculator. The guidelines were to create the project in an 80cm x 80cm x 80cm dimension, have ten transfers of energy, and exceed 15 seconds.

    own machine. While researching, I first looked up the definition of a Rube Goldberg machine. The definition I went off of was as follows: "A Rube Goldberg Machine is a contraption, invention, device, or apparatus that is deliberately over engineered to perform a simple task in a complicated fashion, generally including a chain reaction"(1). The Rube Goldberg machines/cartoons/drawings came about by a man by the name of Reuben Lucius Goldberg. Goldberg was an engineer, cartoonist, inventor, and sculptor. His love of begin artistic and drawing resulted in Goldberg's father sending him to school to become an engineer which resulted in a job designing sewer systems and showing false loyalty to corrupt politicians. Goldberg knew that sitting behind the same desk for the next forty years was not how he wanted his life to go so he quit and began creating cartoons for a local paper. The job was rough at firs, but his talent was eventually discovered and he won a Pulitzer prize for a political cartoon he drew about the dangers of atomic weapons. Goldberg's invention cartoons were influenced by the machine age during the beginning of the century. The reason for these cartoons were because Goldberg believed that people insisted on doing things the hard way and this was his comical interpretation of that. In his own words, the machines were a "symbol of man's capacity for exerting maximum effort to achieve minimal results." With this history of Rube Goldberg machines in mind, I began to create a machine of my very own. My first

    My final thoughts on the project are that creating a machine to do a simple task is just as difficult as creating a machine to do a more complex task. With the two weeks I had available, I was unable to create more then four steps to my project. I believe that the point of the project is to show not only the thought process behind how a machine is created, but also how to manage your time. I fell victim to the theme by trying to make things more complex and unneeded. This project was a sort of preview as to how the Advanced Science class of 2016-17 will perform in the competition

    ...
    rolls down hitting little obstacles that slow down, but slopes that regain momentum.
    The ball starts a row of dominoes to fall
    and hitthe last one hits a mouse trap.
    The mouse trap has rope attached to the bar the slams into the mouse, which pulls the rope
    The rope is tied to a part of a pair of scissors.
    The scissors are pulled together and this cuts a string of hemp that releases a marble.
    This marble moves down a slope and runs into the momentum balls used to demonstrate the conservation of momentum.
    The momentum balls smack into a set of dominoes that collapses into a mini golf ball.
    The golf ball rolls and his a wooden stick with a flat end that looks like a battering ram.
    The battering ram hits the calculator's "ON" button.

    Steps:
    Filled a cut out top of a 2 L. bottle with water that is held by a tea bottle which has a holed drilled through the lid, and a plastic tube that fills up the 2 L. top.

    My Final Project
    {IMG_1579.JPG}
    Analysis
    I ran my machine 5 times. My machine worked perfectly once. It was doing things that it had never done in trial. I had adjusted several things to help with reliability before I brought it to school, but when it got there, things must had shifted. If I had more time I would have made the hole for the first marble deeper so it wouldn't start to roll before it was hit by the metal gate. I would also have build a little wall to keep the marble from flying out on the ramps after the car hits the marble, the piece of wood I had there was not enough.
