Macroinvertebrates and Water Quality Testing

The video introduces a lab activity focused on testing water quality using macroinvertebrates from Legate's Creek. It explains the role of these organisms as indicators of water health, discusses their sensitivity to pollution, and outlines the lab procedure for collecting and analyzing data. The video also compares the advantages of biological testing over chemical testing, emphasizing the long-term insights provided by studying macroinvertebrates.
