If you haven't discovered Maryland's own Bay Backpack (http://www.baybackpack.com/), now's a great time to investigate it. Focusing heavily (but not solely) on the Chesapeake Bay, there's a bounty of books, lesson plans, and other resources to share the educational wonders of this watershed. Many of the resources will go for any watershed/water-side area; additionally, there's other strands of environmental education that are addressed here too.
- academic subjects,
- grade level,
- resource types (be that books, data, lessons, maps, or multimedia),
- or keyword (from "acid rain" to "biodiversity" to "climate change" to "litter/trash/recycling" to "student action" to "wildlife" and everything in between).
So if you're on the lookout for some classroom connections, this is certainly a worthy stop! For a list of their resources, click the title above or go to http://www.baybackpack.com/index.cfm?page=app.resources.
