Home school students Rachel Tillman, 15, from left, Tavie Nichols, 15, and Grace Butcher, 14, find samples of insects and fish Thursday in Clifty Creek near War Eagle. A group of home-schooled students met with members of the Association for Beaver Lake Environment and Audubon Arkansas to learn what makes a stream healthy, what bugs and fish live in a creek and what can be done to keep it that way.
