This week all 4th grade students participated in watershed demonstrations facilitated by Ms. Hodges from Arlingtonians for a Clean Environment. The students learned about point and nonpoint pollution as they "made a mess" of the watershed model. Coming up in the Discovery Lab the students will make their own watershed models. Also, Mr. Bryer will talk about his work with the Nature Conservancy related to the Chesapeake Bay Watershed and the Oyster Restoration project.
