3rd grade challenge #2 - Marshmallow and Toothpick Challenge

Third grade participated in the Marshmallow Challenge!  Their goal was to build a structure that was as tall as they could make it and could also stand up on its own.  We studied different towers from around the world and what made them strong.  They planned, shared plans, picked the best one to try first, and then built.  They discovered over time that triangles really are stronger than squares and we watched videos explaining why.  They were so inquisitive over the differences of what worked vs. what did not.  They encouraged each other as we repeated reminded each other that most great inventions don't happen on the first try.  They are really getting used to this concept and don't let the mistakes get them down for too long.  It's a wonderful process to watch as a teacher.  

Here are some photos of the building process and the presentations at the end.
