Essential Question:  How do land use practices affect water quality and biodiversity in 3 local streams?


Project Summary

This will mostly be a continuation of the watershed research conducted by our AP Environmental class for the past 3 years, but we are going to implement these lessons into our 9th grade Physical Science classes. The watershed curriculum will have two main parts. First, we will conduct an assessment of the overall health of 3 streams in the Petaluma River watershed. This will be accomplished by collecting water quality data (turbidity, specific conductivity, nutrients, and temperature) during and between rainstorms, collecting and analyzing benthic macroinvertebrates (BMIs), and using Google Earth to measure riparian widths. The second part of this lesson students will use stream tables to measure the effects of vegetative cover on erosion and how stream processes affect the distribution of sediment types in the stream channel. We will then compare our results from the stream table models to what we find in our 3 local streams.
