What we're studying:
Engineering, Algebra 1, Computer ScienceOur Team Leader's favorite quote:
\"Wikipedia is a reliable source\" - Mr. YoungWhy we think we should win:
We should win because of the creative and complicated contraptions we included. Also, we spent about 100+ hours working hard on this project. Our Rube Goldberg Machine tells the story of a child growing up.Suggestion for next year's challenge:
- fold a paper
- write on a paper
- pull the cap off of a pen/marker
- flip the page of a book Favorite Rube Goldberg video:
Our Step List
Step 1: Dominoes Activate a wrecking ball type thing.
Step 2: Wrecking ball activates dominoes that go up stairs.
Step 3; The last domino falls off the table pulling the book down
Step 4: The ruler that was attached to the book is pulled out of the slinky
Step 5: Slinky retracts.
Step 6: When Slinky retracts it hits a domino activating it.
Step 7: Dominoes go.
Step 8: Dominoes knock over a book.
Step 9: Book is attached to a string with is attached to a stopper type thing. When the book falls so does the stopper letting the chalk run free and hit the metal ball and it runs down a makeshift track.
Step 10: Ball rolls down a series of tubes
Step 11: Ball eventually hits the final domino
Step 12: When the final domino falls of the table since it is attached by a string to the rc car forward joystick when it falls the joy stick presses forward and activates the RC car.
Step 13: The RC car is used as a pulley and strings attached to the wheels are hooked up around the blackboard and when the forward is presses then it activates and starts moving the string around it.
Step 14(last step): The makeshift eraser that is tightly held in between the string and the board gets pushed down by the string powered by the RC car and it immediately cleans it.
The beginning of the machine starts with the child\'s teddy bear. From there, the baby toy represents the toys the child played with as a baby. Next, there are dominoes that go up and down Jenga Block steps, representing the child when he climbed up and down the stairs of a playground. After that, the ball tied at the end of the string and the red circular surface represents the child being pushed on the swing. When the Jenga Blocks climb up the book stairs, the child enters a new stage of life and he starts going to school to receive an education. Each time the Jenga Blocks go up a step, the child graduates one grade level. During his time at school, he goes to many classes and reads books and uses tools, such as rulers. Next, the slinky falls down the steps to represent obstacles the child faces as he grows. When the slinky hits the next series of Jenga blocks, it shows that even with the barriers, life goes on and he continues to grow. The red toy in the middle of the short series of books shows the play that’s incorporated with the work (books). After that, a piece of chalk roles down a ramp, and hits a ball, causing it to roll down the v-shaped object and the book. This represents the late stage of his childhood when he develops a passion for physics and engineering. The end represents the child being mischievous during school and getting detention so he has to clean blackboards as a punishment.
