VFM0360
Iron Corrosion—Guided-Inquiry Kit
In this guided-inquiry lab, students observe a standard test method for iron corrosion and examine the evidence for the electrochemical model of 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.
