In this module, students begin to develop an understanding of some of the basic principles that answer the question, Why do structures stand up? They look at structures in the school neighborhood, observing the variety in size, shape, material, and function. They build their own structures, using straws, index cards, and other materials. As they build, students explore some of the basic concepts of standing structures, such as live load, dead load, tension and compression, the role of shapes, and trusses. By comparing their structures with those in their community, students learn how structure and design are influenced by function, materials, and aesthetics. The last activity in the module challenges students to design and construct a unique piece of playground equipment. |
