This lesson should follow immediately from the lesson where urban tracks of land bordering a river are "developed" by students according to sound/unsound principles, only to find that when their tracks are connected, what one track ("township") does with their land directly affects the township below it. Thus, who manages a shared resource such as water?

Begin by introducing the idea of a "riverkeeper"; and explore the notion of a river having "rights" that go along with this role. Quote the DE Riverkeeper.

Guided Notebook Entry, K-W-L Chart: Riverkeepers
Guide the "K" column
-waterways are a shared resource
-waterways have lots of uses (transportation, development, agriculture, recreation, etc.)
-"Riverkeepers have something to do with protecting the river. From What?

-Have students go to computer lab investigate DE River websites Delaware River Action | Delaware Riverkeeper Network, Delaware Riverkeeper) and fill out Research Handout (this will consist of minimal writing and allow for responses to be based solely on pictures. Teacher guidance provided on a 1-on-1 basis. ELL students partner w/others, also. The handout will ask for 4-6 actions taken by riverkeepers and their organizations, and identify the one they think is the most important/one they would want to get involved in. Complete K-W-L chart as group, then individually. Keep written demands low, discussion level high. K-W-L chart filled out with minimum words.
