This column provides an inside look at the marvels of engineering in everyday life. This month's issue describes a 5E-learning-cycle lesson where students test different types of coatings on pennies to observe how the coatings affect the amount of corrosion produced when the penny is placed in a moist environment and a moist, acidic environment.

This article provides a directed inquiry activity on chemical changes brought on by corrosion. It is inexpensive to implement. I have done similar activities with students but this one provides extensions that tie it into engineering by having students look at applications of coatings to provide protection from chemical changes. Simple but effective way to include engineering with a simple science experiment.

This article is best described as follows..."In this 5E-learning-cycle lesson, students test different types of coatings on pennies to observe how the coatings affect the amount of corrosion produced when the penny is placed in a moist environment and a moist, acidic environment." The lesson plan is explained in great details. It goes on to explore coatings in many situations and how they affect objects.
