In this video segment, participants attempt to build freestanding structures with toothpicks and mini marshmallows. Watch this segment after you have built your own freestanding structure, and compare your strategy with that of the onscreen participants.
What kinds of shapes did the onscreen participants use in their structures the first time? How did some of the groups revise their strategy? How did your structure compare with those of the onscreen participants?
If you are using a VCR, you can find this segment on the session video approximately 18 minutes and 50 seconds after the Annenberg Media logo.
