It's OK to not know, but it's NOT OK to not try.
The Design Challenge Question was "How can I work with my peers to create a cup stacking structure?" We used all 4 quadrants of the Design Cycle: analyze, design, create, and evaluate.
The "Thomas Twist" was we couldn't use any part of your body to move the cups. We could only use a piece of string or a rubber band with strings attached. Later on in task 4, we couldn't verbally communicate. We used the learner profile attributes communicator and risk-taker because we tried something we have never done before and had to work in groups.
The strengths were working together as a team and not giving up. The struggle was figuring out how to use the tools that we had to work with (rubber band and string) to pick up the cups. We were able to get to the 4th task, which was stacking cups of 2 different colors using only a rubber band without being able to talk to our group.
I never knew that cup stacking was a world sport! Here is the link to Speed Stacks, the official cup of the world sport stacking association. See the pictures below of the 8th grade classes in action!
