        Images of the Past | Reaction Rate: Surface Area

        During this activity the students will learn about a tragic 1930 fire at the Ellison Shaft, Homestake Gold Mine, which claimed the life of two men. They will also use household items to investigate how an increase in the surface area of a solid reactant increases the reaction rate of a chemical reaction. Finally, they will learn how adding chemicals like aspirin to a sewer system is damaging to the environment and water supply.
