Is Paper Strong?

This is the question we considered yesterday and today in room 6 during science. As we launched into our Strong and Stable Structures unit, the grade 3’s were challenged to make a bridge using 3 pieces of paper. The results from Trial # 1 led us to conclude that paper was not very strong – most of the bridges held only 3 or 4 pennies before collapsing. After considering different shapes that paper could form through folding or rolling, students set off to redesign their bridges. The results from Trial # 2 were significantly different from Trial # 1. For more information check out the pictures below and discuss the experiment at home.
