2nd grade - marshmallow challenge

Second graders were tasked with building the tallest structure they could using one cup of marshmallows and 50 toothpicks.  They used the engineering design process to complete this project.  They brainstormed ideas; wrote plans; gathered in groups to discuss the merits of each plan; picked their best idea as a group; and then built (and re-built) until it was right.  We had melted marshmallows one day due to unseasonably high temperatures which made it even more challenging (and not on purpose!).  We had to rebuild from that disappointment.  We decided that weather happens and you can't predict everything.  We learned to make the most of it and sometimes just start all over.  In the end each group presented their final project and explained how the process went.  One student pointed out that you can't always tell from the finished project all of the interesting things that happen during the build.  I think that's an excellent metaphor for life in general.  Sometimes the path is more important than the destination.  I'm super proud of these second graders discussing such mature concepts.  Who knew what marshmallows and toothpicks could bring to a class discussion??  :)
