The Breakdown: Exploring Corrosion Science

Topic: In this hands-on team-based activity, students will explore the science behind corrosion. They will discuss the factors that contribute to corrosion and how this can be avoided. They will consolidate this knowledge with a hands-on nail rust experiment.

Time: 60 minutes; implemented in one session

Materials:

• Pre-Activity Checklist

• Tell My Story Form

• Computer with projector, speakers, and Internet access

• PowerPoint: The Breakdown – Exploring Corrosion Science

• Video: How to Clean the Eiffel Tower
