You are a historian who is compiling information on the changing materials used in a product in one of the categories listed below. Choose a product that uses a variety of materials that have been discussed in this lesson (for example, a car or a tennis racket). Using online or library resources, research past materials used to create the product. Be sure to discuss the materials currently being used for the design and include information on the sustainability of these resources. Your research must also explain why the materials changes were made (for example, safety, cost, or weight). Keep track of your references so that you can document all of the resources used for your report.
