So now this week we're trying out our engineering skills, learning all about bridges, loads, arches, suspension bridges, cofferdams, cantilevers, etc. Here's a few of our experiments, with more to come tomorrow. Who knew a bridge made of 3 pieces of paper could hold 15 hot wheels cars!?! Another recommended read: "The Brooklyn Bridge" by Elizabeth Mann and "Bridges! Amazing Structures to Design, Build, and Test". Maybe I'll have boys at the International Science Fair someday following in Uncle David's footsteps.
