Bridge Busting






Those of you who studied architecture may remember this project. You spend weeks building a bridge only to see it broken while testing its structural integrity. Our science class spent weeks studying bridges of all sorts and especially the fabled Brooklyn and London bridges because they have such rich stories. After trying different styles using a model kit, we built a bridge of our own. As we worked, we spoke about human adaptation and ingenuity, engineers working with and against nature and managed to touch on an array of STEM concepts such as basic geometry, cofferdams, torsion (think Galloping Gertie!) and most importantly, live loads. Our bridge was able to hold a live load which included a full set of gram weight units, a pile of clothespins, twelve wooden elephants, a clown, two skeleton models, and a cup. It took the World Atlas to finally bring it down!
