The were asked to build the tallest free standing Tree with unlimted amounts of Gummy Bears and toothpicks. They were allowed 3 questions for help from a teacher.
Once they had decided to stop building, they were asked to measure the height of the tree, count the toothpicks & bears used to record on their data page.
After the time limit was reached, winners were declared. The children learned a great deal and were shown an example start , a picture and several hints about the importance of a stable base.
Each child approached this problem differently which was interesting to watch. We were able to discuss flexibilty a great deal as many had to change their minds because their tree wouldn't stand up.
There was ample opportunities for problem solving, giggling and quiet focus and reflection.
