What Is a Rube Goldberg Machine?
A Rube Goldberg machine is a machine intentionally designed to perform a simple task in an indirect and overly complicated way, relying on chain reactions. Using a variety of simple machines.

This is our final blueprint shown to the right. This shows our final steps and all the calculations for each one.
This next piece of evidence of work is the video of our whole project working flawless.
My Work
During the span of building our Rube Goldberg machine, I installed many steps and many different slides in our presentation. For this project, I installed Steps 2,3,4,8,9 and 10. I mostly screwed all our steps in and made sure that the marble wouldn´t get stuck anywhere or go off track. For step 4 I cut two pieces and screwed them together to make our second incline plane. For step 9 I designed a wheel with one container a marble would drop into. The wheel is designed to spin when the weight of the marble applies a force to it. One Big challenge I did face during this was the rush to get everything done on time. On our last day, the slideshow was nowhere near done at all and we needed a lot of work to get that done. So over the weekend, I attended Saturday Academy to make sure our slideshow was ready and all set for our presentation. I got a lot of our calculations and filled out a variety of slides. Some problems that we faced were when our build was put away after building time the next day a lot of things broke off and got ruined. This meant we had to keep making sure everything was fine and would end up working. The last problem we faced was having to improvise and make new steps on the spot because a lot of measurements were wrong and did not fit well on our board. One thing I would change from the beginning would be our blueprint because we were a little slow the first couple of days so I wish we had a completely correct blueprint to follow so we weren't so rushed. Our biggest success was getting everything to work at once.
Content
Velocity-"the speed of something in a given direction." Velocity is in our project when the foosball rolls down the track. (Slide 19)
Acceleration-"Increase in the speed or rate of something." Acceleration is found in steps 2,4,8 and 10.
Force- "The push or pull on an object with mass causes it to change its velocity." Force is found in steps 1, 7, and 9. The force of the marble causes steps to move
Work- "the transfer of energy by a force acting on an object as it is displaced." There is work in our pulley system, wheel, and domino.
Potential Energy-"energy that is stored within an object, not in motion but capable of becoming active." potential energy is steps 1 and 11.
Kinetic Energy-" the energy of motion, observable as the movement of an object or subatomic particle" Kinetic energy is in all of our steps besides steps 11 and 1.
Mechanical Advantage-" a measure of the ratio of output force to input force in a system" Mechanical advantage is in steps 3, 7, and 9.
Simple Machines- "any of several devices with few or no moving parts that are used to modify motion and the magnitude of a force in order to perform work." Our simple machines included are inclined plane, wedge, wheel, pulley and screw. These are on the slides 6-11.
Blueprint-"architect plan, technical drawing or engineering design" Our Blueprint is on slide 5 and it shows our exact measurements for each step and how big it is on our project. It shows how many meters log everything is in scale.
Construction log- " A log in which collects data of what was done over a course of time." For our construction logs, we had 9 days we logged and put all the work done on that day.
Day 1-Transferred blueprint on board and got materials.
Day 2-Attached step 1 (inclined plane).
Day 3-Cut wood and attach decoration to the inclined plane.
Day 4-We cut our next incline plane, and made a screw while also attaching both.
Day 5-Attached our next incline plane.
Day 6-Fixed any small problems.
Day 7-We put on steps 5,7,8 and 9.
Day 8-We put pieces together and made sure everything worked.
Day 9- We decorated and attached the final steps.
Reflection
During this project, I developed some new skills such as critical thinking and conscientious learning. I developed critical thinking when our group needed to make a decision on how to build a step and I came up with a way that it would work. I developed conscientious learning when we needed to build our steps to work and I installed them correctly and made sure they would work on most of the times we ran our project. I do wish that I could improve my collaboration and communicate in a better way so we could get work done more efficiently. I lastly wish that collaboration was incorporated with me in this project so that all things would be easier and fewer problems would come up.
