The Impact of Beaches
After learning about the effect of geology and tides and how it has contributed to the magnitude of Hurricane Sandy’s devastation, Mazel 3rd, 4th, 5th, and 6th graders are now shifting their focus and learning about how beaches and marshes protect mainland Brooklyn from hurricanes. Last Friday the students learned about the impact of beaches and this Friday we will learn about the influence of marshes. On May 10th, we will combine what was covered in both of these classes and apply the information during the field trip to Salt Marsh Nature Center.
As you can see from the diagram of beaches
below berms provide a barrier for water erosion creating a dune that protects the shoreline.
Due to class discussion, students suggested an idea to build a model
that they can use to explain how beaches and marshes in their natural state are
wonderful defenses. The model will also describe how human impacts and the built
environment deplete this natural defense. The students will solely figure out how to develop a model that represents the purpose of beaches and marshes as well as what we can do now that they have been developed into an urban area.
