Lyons Elementary students explore environmental leadership with STEM focus

Lyons Elementary fifth graders on Thursday donned waders and grabbed screens, then walked into a shallow section of the North St. Vrain River in LaVern Johnson Park.

Two students held the screen, while a third loosened rocks to disturb the riverbed and the macroinvertebrates living there. Then they took the screens to the bank and poured water over them, washing what they collected into tubs.
