Change, Watershed, and the Chesapeake Bay

DSC00784 We all live in a watershed, which consists of the land surface that drains into a local body of water, such as a stream or river. Our behavior impacts our local streams, like Lubber Run and Four Mile Run, as well as the Potomac River and the Chesapeake Bay. A watershed carries water “shed” from the land after rain falls and snow melts. Drop by drop, water is channeled into soil, groundwater, creeks, and streams, making its way to larger rivers and eventually the sea. Water is affected by all that it comes in contact with: the land it traverses, and the soils through which it travels. The important thing about watersheds is: what we do on the land affects water quality for all communities living downstream. DSC00851 Barrett School Theme: CHANGE

  • Change affects people, animals, plants, and objects.

  • People, animals, plants, and objects can change.

  • Change can be easy or hard, positive or negative.

  • Change can happen slowly or quickly.

  • We can often predict change, but sometimes a change is surprising.

  • A need or a want may cause change. Also, a change may cause a need or a want.


This week students were encouraged to think about CHANGE in connection with the following lessons in the Discovery Lab:

· Examining Chesapeake Bay animals and plants from the Virginia Living Museum

· John Smith and the Chesapeake Bay

· Watershed Model with Mrs. Hodges from Arlingtonians for a Clean Environment

· Mr. Bryer from the Nature Conservancy – Chesapeake Bay, Watersheds, and Oysters

· Creating your own watershed models

· JASON Project – Dr. Robert Ballard, Dr. Sylvia Earle, and the Student Argonauts We hope you enjoy the photos below of the watershed models made by the 4th graders.
