Online Division I - Ages 11 - 14 (Middle School)
What we're studying:
Physical Systems; Levers; Pulleys; Mechanical Advantage; Simple Machines; Energy Transfers; Fluid Dynamics; Density; FLow Rate; Viscosity; Buoyancy; and Canadian HistoryOur Team Leader's favorite quote:
"Try it and see if it works" and "I love it."Why we think we should win:
We think we should win, because we used 90% recycled or re-used materials; we have a lot of different kinds of energy transfers, but no marbles or dominoes; we stuck very closely to our theme (every province and territory in Canada was represented in our machine as well as some national landmarks and historical points); we decorated the machine in appropriate colours. We payed very close attention to detail. And most of all, we had a ton of fun making our machine.Suggestion for next year's challenge:

Hello Rube Goldberg Fans! We call ourselves “The Eh Team” because Canadians say “Eh?” a lot, and we are Canadian! This year is Canada’s 150th birthday, and that’s the theme we chose for our Rube Goldberg machine. We thought it would be fun to try to incorporate a little something from each of our 10 provinces and 3 territories along with a bit of Canadian culture and history into the steps and decoration of our Rube Goldberg machine.
Our machine is made from 90% recycled or re-used materials, such as strong cardboard packing material for the main structure and Inukshuk, and blue plastic shopping bag for part of our riverbed. We used old toys, such as a basketball, hockey pucks, modeling clay, slinky, plastic sheet toboggan, and model of the Canadian National Tower, and donated materials, such as the wood sample chips in our staircase.
The first steps of our machine at the top of our structure represent Canada’s northern territories. Our Inukshuk is a model of a type of large landmark built by Native Canadians in far northern areas to help travelers navigate in a land with no trees and vast flat areas, such as in the territories of Nunavut, Yukon Territory, and Northwest Territories. The yellow knife that acts as a lever stands for Yellowknife, which is the capital of the Northwest Territories. We also included a white horse in the machine, because White Horse is the capital of Yukon Territory.
Our staircase made of wood is a reminder of the huge and beautiful forests of Newfoundland & Labrador and British Columbia, our more southern coastal provinces.
The middle steps of our machine represent the interior of our country, the Prairie Provinces, where a lot of food is produced. Our inclusion of bread recognizes the huge wheat production of the provinces of Saskatchewan and Manitoba. We used molasses to represent the large oil reserves of the province of Alberta, and pucks to represent hockey, which is our most popular national sport right across the country.
We represented our maritime provinces using several symbols: pucks for the great Nova Scotian hockey player Sydney Crosby; a flatrock to stand for the Flowerpot rocks in the Bay of Fundy in the province of New Brunswick; and a red clay ball to stand for the iron-rich soil and red beaches in the province of Prince Edward Island.
We especially enjoyed creating a replica of the great St. Lawrence River, which flows mostly through the province of Québec and connects the great lakes with the Atlantic Ocean.
The final step in our machine raises a model of the Canadian National Tower (CN Tower, for short). The tower is located in the province of Ontario but is special to all Canadians, because it held the record for the tallest free-standing structure in the world for 34 years until 2010.
Happy Birthday, Canada! And thank you, Rube Goldberg fans, for listening to the story our machine tells.
Our Step List
1. Team member starts slinky down staircase.
2. Slinky topples Inukshuk.
3. Inukshuk triggers Yellowknife lever.
4. Yellowknife lever starts basketball rolling.
5. Basketball rolls down ramp and hits bucket of oil.
6. Oil flows onto bread, soaking it.
7. Soaked bread falls down chute and hits hockey puck.
8. Hockey puck slides down ramp and hits stacked hockey pucks attached to a pulley.
9. Pucks on the pulley raise the flat rock, tipping over the bucket.
10. Tipped bucket sends water and red clay ball down chute.
11. Flowing water and rolling ball’s pressure knock cluster of golf balls on a pulley off its perch.
12. Golf ball cluster falls triggering 3-pulley system which raises Canadian National Tower.
13. CN Tower applies Band Aid© to surface.
