Description This is a two-part investigation (developed by SEPUP) into the chemical concepts that underlie corrosion and our attempts to inhibit it. In the laboratory portion of this activity, students investigate this concept using iron, steel, aluminum, and zinc metal. They investigate the impact of factors such as salinity, coatings, and contact with other metals on rust and corrosion. Students also complete a reading that describes some conditions that affects the rate of corrosion of iron and steel and several chemical principles associated with these conditions. The activity concludes with a discussion of the impact on materials and the environment.
