A few weeks ago, Savannah came home with an assignment to build a bridge. Made of nothing but toothpicks & Elmer's glue. It had to fit some particular measurements & had to hold at least (I think?) 5 pounds of weight before breaking. The kids were told to get online & research various bridge structures and decide what design they would use & start building.
And so, for the past 2 1/2 weeks, Larry & Savannah have commandeered the coffee table with (seriously) over 1000 toothpicks & 2 bottles of glue and all sorts of printed & hand drawn 'blueprints' for The Bridge.
After lots of deliberating about the best design, they created this bridge.
Today, Savannah turned it in & they tested it to see how much it would hold. I was totally stunned when she got in the car this afternoon telling me that it had held EIGHTY EIGHT pounds before it broke! Hers was the 3rd strongest among her whole grade! The strongest one held 111 lbs! Wowza! Maybe I have a bridge engineer on my hands?!
