Density Sub Plan (No Prep): Mystery Material Case Files, Grades 5-8

Eight mystery objects turned up in a lab. Students open eight case files, each with a mass and a volume, calculate every density, and match the density to a table of five real metals (aluminum, iron, copper, lead and gold) to name the metal, or write "none". Then they predict sink or float for every object in water and in a made-up Liquid K, and finish by finding the densities of four made-up liquids and drawing them in order in a liquid column.
