Summary
Through a demonstration, students learn about the balance between subsidence and flooding in the formation of a wetland. Students then watch a short 15 minute PBS video about the wetlands of Louisiana. They will discover how levee building and the subsequent loss of wetlands contributed to the severity of Hurricane Katrina’s effect on the city of New Orleans. Finally, the class holds a discussion geared towards environmental stewardship and habitat restoration.
