This is a two-part investigation into the chemical concepts that underlie corrosion and our attempts to inhibit it. In the laboratory portion of this activity, students investigate the corrosion of 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 of corrosion on materials and the environment. Developed by SEPUP.
