What we're studying:
Major Technological Advances that led to huge changes in human life.Our Team Leader's favorite quote:
'Fall 7 times, get up 8.' - Japanese ProverbWhy we think we should win:
Our Rube Goldberg Machine shows advancements in technology as an evolution over time. Our machine actually tells a story! Everything in life is built on the back of something else, nothing comes from nothing. One invention leads to another, leads to another... One student compared it to the circle of life. Another student smartly pointed out that, since The Big Bang, everything has evolved from something else.
Our machine is informative, compact and made with recycled materials such as computer cases, yogurt dishes, leftover wood scraps, discarded cardboard and even a bicycle fork. We also think that our tree representing the Green Revolution is especially great.Suggestion for next year's challenge:
wipe a table, throw a football, sharpen a pencil, screw a screw, draw a line, write hello, take a picture, play music on a playerFavorite Rube Goldberg video:
Our Rube Goldberg machine has 11 steps in order to open the umbrella. Our theme is 'Great Technological Inventions.' We start with the Lever in the 3rd Millenium B.C. and the Nail in 2nd Millenium B.C. and go all the way to the invention of the Internet in the 1960s.
Our Step List
1. Ball is dropped down the 'Plenko' board and falls into the green basket which weighs down the basket, pulling on the blue ring and unhooking the paperclip from the binder clip.
2. The paperclip unhooks from the binder clip letting the bent ruler swing back to being straight.
3. The ruler hits the pipe with a rubber end on it which pushes the paint roller within the white tube.
4. The paint roller rolls forward slightly to scoot the weights off the top of the computer case; the weights fall into the bucket below.
5. The weight in the bucket causes the lever to enact and lift the board that is holding the tape roll back on the zipline.
6. After the board lifts, the tape roll goes down the zipline to hit the first domino.
7. The dominos fall.
8. The last domino is holding up a bocce ball attached to a string that will hit the rest of the bocce balls in the Newton's cradle.
9. The last bocce ball hits the back end of a car that then falls off the end of the table.
10. A string is taped to the backend of the car so that when the car falls- it pulls the loop tied around the end of the bicycle fork glued onto a stand at the same time as the string pulls loose from the tape.
11. This string is attached to a bocce ball sitting at the top of an upside down bicycle fork. When the string is loosened, the bocce ball rolls down the fork to hit the button on the umbrella, opening the umbrella.
