We have some budding architects in the Grade 1/2 class.  In studying structures, we discovered that triangles make great supports, stale marshmallows hold spaghetti better, and shorter pieces of spaghetti make a structure stronger and easier to move.  We discovered that  strong foundations allow us to build taller structures.  We had a great time designing and building structures outside as well.  Our next adventure will be making popsicle stick bridges.
