Structures: Bridges

Today in class, we made two different paper bridges using arches and triangles.  We learned that those shapes make bridges STRONG and STABLE.  We have also tried standing with our feet together and then spreading them apart to explore what it means for a structure to be stable.

Watch this video with pictures of bridges from all around the world.  Do you see any arches or triangles?
