Second graders spent part of a class period brainstorming their bridge designs. Now, working in teams, second graders are using their discussion techniques to design a bridge together.
Their plans must include a labeled diagram of their bridge design, including the materials they'll use!
Next week, they'll begin testing their bridges to make sure they can hold weights, allow cars to pass over them, allow a barge to pass under it, and be wide enough to cross the span of a river.
