Galvanized Sheet Metal Lab

This module, created by Jamie Acker of Olympic High School in Bremerton, Washington, provides a look into an entry-level lab on galvanized metal. The introduction states, "This simple lab visually shows the effects of removing zinc from a galvanized piece of sheet metal and provides students an opportunity to mathematically calculate the reduction in thickness of the zinc and number of atoms lost, based on the change in mass." The module features an abstract, objective, curriculum overview, procedures, mathematical calculations and references. Students should gain knowledge taking measurements using a micrometer/beam balance, how to safely handle strong acids and use algebra to rearrange equations to balance equations. This is a great resource to either enhance or create new curriculum for instructors.
