There are four main objectives in this unit. The first will be to understand causes and effects, then how they relate to the assembling of bridges. The second will be to compare and contrast the specific bridges. The third will be to identify the main parts of lift, cantilever, and arch bridges and to tie in the vocabulary terms connected with them. The fourth will be to design lift, cantilever, and arch bridges, from stencils, that they can be assembled permanently. They will be used as the main objects in the "Assembly" game. The students will develop the rules for this game, plus possible improvements in the stencils.
