Lab-Aids: Investigating the Chemistry of Corrosion Kit

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.
Scientific Concepts:
  • Substances react chemically in characteristic ways with other substances to form new substances (compounds) with different characteristic properties
  • Metals are a group of substances that react in similar ways. Corrosion is one type of reaction that affects metals
  • Metal corrosion is an example of an oxidation-reduction (redox) reaction, which involves the transfer of electrons
  • Students summarize results of an investigation and form a logical argument about the cause-and-effect relationships in the investigation
