During this unit students learn that matter can be described and classified by its observable properties. They test a variety of materials to determine which have properties that are best suited for an intended purpose. Students will ask questions, make observations, and gather information about a simple problem that can be solved through the development of an improved object. They then make a recommendation to SURF engineers about which materials they consider to be the best fit for the job and why.
