Grade 8

Submerged Aquatic Vegetation (SAV) Study
Fall and Spring
Locations: Dundee Creek or Days Cove

Essential Question: In what ways have humans impacted the SAV populations in the Chesapeake Bay and its tributaries?

Through a study of Submerged Aquatic Vegetation (SAV/underwater grasses) at Dundee Creek or Days Cove, students will determine how human activities have impacted the environment. They will investigate biotic and abiotic factors that influence SAV growth, native and non-native species, and the importance of SAV to Bay health. Students will collect data using digital and manual data acquisition tools and SAV sampling rakes. Students will analyze collected data to determine the current condition of SAV. This field experience can be coupled easily with the Chesapeake Bay Foundation’s “Bay Grasses In Classes.”

Content Standard: Environmental
Topic: Environmental Issues
Indicator: Recognize and explain how human activities can accelerate or magnify many naturally occurring changes.
