Stream Simulation

Welcome to the Stream Simulation!

In this simulation, you will collect a sample of macroinvertebrates from a stream. These macroinvertebrates fall into three categories: Pollution Sensitive (3 points), Somewhat Pollution Sensitive (2 points), and Pollution Tolerant (1 point). The more sensitive critters you find in a stream, the better the water quality. Once you identify the macroinvertebrates in the stream, you can total up their score and determine its overall quality.
