inquiry- building bridge

Today for inquiry in my group we collaborated to make a plan about making a bridge tat long and flat and strong bridge we did the deck of the bridge is compete so we have to make the arch the top of the bridge and the triangle at the bottom deck and I learnt that triangle is stronger shape than any else shape for a bridge and the arch is strong to it make a bridge stronger and stronger . In my group there names is Dallas , Aung naing ,Neveah , and me and my used toothpicks to make a bridge it is very very hard to think about how we going to make the bridge .
