Macroinvertebrate Observation Techniques

The video tutorial covers the identification of macroinvertebrates to assess water quality. It guides students through setting up a USB microscope, accessing online lab resources, and digitizing lab work using Google Docs. The tutorial also explains using split screens for efficient lab work, capturing and annotating images with Spark View, and exporting and inserting images into documents.
