This lesson will explore the phenomenon of corrosion as students learn about sunken ships in the Great Lakes and the glass-bottomed tour boats that take people to explore them. In doing so, they’ll delve into such science topics related to exploring shipwrecks as gas laws and more.

• Know what corrosion is and why it happens
• Understand how gas pressure changes with depth underwater affecting scuba divers
• Be able to model the chemical change process of corrosion
