Project 1. River Biotic Index

The purpose of this activity is to conduct a basic measure of watercourse invertebrates that indicates the water quality of a certain point in the watercourse. After catching the specimens, students can identify the species and their according score in relation to an accompanying chart. The resultant combined score can provide a snapshot of the scale and quality of a watercourse. Each invertebrate has a score out of 10 which indicates the water quality.
