Objective
The main reason for making the model is to allow the students to solve a design task: build a small scale model of The Brooklyn Bridge.
Development
The model of The Brooklyn Bridge that students will build will be in proportion to the actual bridge. However it will be assembled differently from the way the actual bridge was constructed since the students will use other type of light weight materials such as balsa, cardboard, fishing line, and ropes.
