We took a big leap and tried out a whole-grade suspension bridge building activity in the 3rd grade today! The idea comes from an activity in the book Engineering the City by Levy and Panchyk. In the text they outline how to use cardboard and paper clips to make a model suspension bridge that can actually hold up an impressive amount of weight. It was a big challenge for the kids to persist through since there were plenty of little things to be rebuilt along they way. They had great help from their teachers and really felt accomplished once they were finished though!
