Lab-Aids Investigating the Chemistry of Corrosion (Developed by SEPUP)
Summarize results of an investigation and form a logical argument about the cause-and-effect relationships in the investigation.
Manufacturer: Lab-Aids 86S
DescriptionThis 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. Accommodates up to 4 classes, each with 6 groups of 4 students. Includes Teacher's guide, student sheets, assessment questions and SDS for all chemicals.
