Product Description

By: The Flinn Staff


Rust is expensive! The cost of iron corrosion for equipment maintenance, repair, and replacement tops $300 billion per year in the United States alone. What kinds of conditions or treatments will reduce or prevent the corrosion of iron? In this guided-inquiry lab, students observe a standard test method for iron corrosion and examine the evidence for the electrochemical model of corrosion.

When iron nails are placed in agar containing indicators, different colors develop at the sites of oxidation and reduction, respectively. Students brainstorm what kinds of chemical treatments, surface coatings, and combinations of metals may inhibit or prevent corrosion. They then design a “fair test” experiment, using the standard method, to determine the validity of their hypothesis. By reviewing results with those of other groups, students are able to compare the effectiveness, advantages, and disadvantages of various methods of corrosion protection. Includes Teacher Notes with complete sample data, comprehensive background information, reproducible student handouts, and all chemicals and consumable supplies needed to perform a variety of guided-inquiry lab tests.

Complete for 30 students working in groups of three.
