The Benthic Macroinvertebrate Portal is just one component of the Potomac
Highlands Watershed School's watershed science and society curriculum, and is
best used when accessed from within an eSchool classroom. If you reached this page
via a direct web-link, you might consider going to the
Potomac Highlands Watershed School and visiting an eSchool
classroom to use this and other activities, review the literature in the bookshelf or, if
you are a teacher, visit the "Teacher's" room and check out the lesson plans.
