Recently in my after school Science with Everyday Objects class we tried out some engineering experiments. We discussed using squares versus triangles as basic building blocks for structures. Then the kids created their structures and we tested how well they could bear weight. We used books and toy cars as weights. The strongest structure held 6.5 pounds (as weighed on a kitchen scale)and could have gone on except we ran out of toy cars to pile on top. Then we tried spaghetti and marshmellos. Not as successful. The spaghetti was too brittle and broke when they tried working with it. The kids still had fun trying. See ZOOM for this and other building project ideas.
