Chaperone Janette Keller watches over a group of Hannah Beardsley Middle School students searching through a silt screen for critters found in a stream behind Prairie Ridge High School Tuesday, May 8, 2012 in Crystal Lake. The event, organized by seventh grade biology teacher Carol Sevrey and Friends of the Fox, gave students a chance to gain hands-on experience and apply skills learned in the classroom. Students at the event measured the physical, chemical, and biological conditions at sites along the stream.
