Live Division I - Ages 11 - 14 (Middle School)
What we're studying:
We learned about Newton's 3 laws of force and motion, as well as the difference between kinetic and potential energy. Our science teacher also let us explore the 6 simple machines, particularly the lever.Our Team Leader's favorite quote:
Does an earwig have 6 legs?Why we think we should win:
Who knew that dominoes could climb up a hill!!! Suggestion for next year's challenge:
We want to peel a banana.Favorite Rube Goldberg video:
The Earwig! We used random parts from the science classroom and attached them to an adjustable frame that was dreamed up by our science teacher's dad.
Our Step List
1. A string is pulled, which is attached to a nail, which is holding back a billiard ball that is inside a recycled cardboard box that is fashioned into a tube.
2. The released billiard ball rolls down the tube and falls into a bucket on a string that is sitting on a mini table.
3. The weight of the ball makes the bucket fall off the mini table, and it swings on the string until it hits a board holding up a large wooden block, which falls.
4. The large wooden block is attached by string and a set of 2 pulleys to a strip of plastic that is holding back a soccer ball. When the wooden block falls, the plastic strip is pulled down and the soccer ball is released.
5. The soccer ball rolls down a ramp and is directed by a piece of lumber to knock down a board that is supporting a billiard ball on a string.
6. The billiard ball on a string now swings to hit the first giant domino.
7. The dominoes fall on each other going UP the ramp in order to hit the final domino that is attached by a string and pulley to a nail in a tube.
8. The final domino pulls out the nail in the tube, which releases a billiard ball that travels down the tube into a colander.
9. The weight of the ball makes the colander fall, which pulls on a string attached to a piece of metal precariously placed under another billiard ball.
10. The metal piece is pulled out by the falling colander, so the billiard ball rolls down a mini ramp and hits a roll of red caution tape.
11. The roll of red caution tape gets knocked off the platform and travels down a string which is attached to a spring loaded umbrella. The weight of the tape pulls the string down and the umbrella is released! And just in time because it has rained a lot this past week!
