After an introduction and a snacktime, the students split into small groups and rotate through the following four stations.
Understanding Watersheds
Students walk out on the boardwalk to the water's edge. From this vantage point and using binoculars, students can see the mountains that create the Bay's watershed. With a paper watershed model, they spray water to see how rain flows into the valleys.

Pollute the Watershed
The teacher guides students through polluting a model of a suburban watershed. They take turns sprinkling different materials and colored sugar that represent pollution such as pesticides, soil, car oil and more. Then students spray water on it and watch the discolored and polluted water flow into the creeks and Bay.

Water Testing
Students run water quality tests similar to those performed at the wastewater treatment plant, such as nitrates, phosphates, dissolved oxygen, pH, and turbidity. They test water from the marsh and treated wastewater for comparison.
Walk to the Outfall Pipe
Students watch a short video about the wastewater treatment plant, which is located in the Baylands. It shows how sewage is treated there. Then students walk to see the outfall pipe where treated wastewater is released into the Bay. They discuss how they can prevent water pollution.
