Class Project - Healthy vs. Unhealthy Stream Model

As part of our Columbia River Gorge studies, students have been working on visual models of healthy and unhealthy streams.  We have been discussing categories of streams that involve levels of toxic chemicals, temperature, dissolved oxygen, and bacteria.  In the photos below, students are creating elements of healthy and unhealthy streams such as the Riparian Corridor, riffles, dissolved oxygen, pipes, dams, factories, and roads.  Ask your child for more details on how these elements affect the stream!
