Ms. Boyd's AP Environmental Sciences Class from Prattville High School took a field trip to the Alabama Wildlife Federation headquarters to learn about aquatic invertebrates, water quality testing, catfish, fish tagging and population estimation.

PHS students collect some water to test for pH, chloride, nitrate and total ammonia.
