What better way to learn about stream ecology and water pollution than to collect and identify the fascinating insects, crayfish, and shrimp-like scuds living in streams? ICPRB provides presentations, hands-on activities, and resources to help teachers (middle through high school classes) start stream ecology or monitoring programs. The presentations can be done as a series or as stand-alone lessons.

Bilingual lessons in English and Spanish are available on the Bilingual Materials page.

*PDF Presentations marked with an asterisk (*) have a companion PowerPoint presentation. Please Contact us for the file.
