Collecting and Identifying Benthic Macro-invertebrates for Water Quality Assessment

Philippe Cousteau joins students from Petersburg Elementary to learn about benthic macroinvertebrates and their importance in assessing water quality. The students demonstrate how to collect these organisms using a kick net and then sort and identify them with a dichotomous key. The process involves checking for characteristics like shells, legs, and tails to determine the type of macroinvertebrate. This hands-on activity highlights the fun and educational aspects of science.
