Everyone wants clean water, whether for our own use or as part of a healthy natural environment. Water quality of streams is generally determined by monitoring the insects that live in the stream, with healthier streams producing a greater variety of specialist insects. As part of a team of entomologists, computer programmers, and learning researchers, we created an extraordinary teaching resource that turns your computer screen into a microscope that you drive. Expert instructions show how to identify insects important in water quality analyses. A phone app permits some of the same utility in a portable fashion.
