=Summary=

===Students will produce a lab report on testing the properties of various materials (such as pine, oak, ceramic, steel, reinforced concrete, glass, and carbon fiber). They must then design and build a structure capable of enclosing a given space and capable of surviving the elements of their local climate. ===

 * ===**6.G.4 **. //Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. Apply these techniques in the context of solving real-world and mathematical problems.// Students will represent bridge as three-dimensional figure composed of rectangles and triangles and find the surface area of designed net. ===
 * ===**7.G.1 **. //Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.// Students will solve problems of unknown amounts of materials for bridge building from scale model they draw. ===
 * ===**8.G.7. ** //Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.// Students will use the Pythagorean Theorem to determine unknown side lengths of right triangle supports for bridge. ===
 * ===**G-MG.3 **. //Apply geometric methods to solve design problems.// Students will design a bridge with the aim of minimizing costs and satisfying the physical constraints imposed by the location and materials. ===
