LACKAWAXEN, PA — “Backyard Biology” is offered to students in grades three through six by the National Park Service (NPS) every Wednesday during the summer, at 10:30 a.m. at the Zane Grey Museum. For one hour, students will learn from an NPS Ranger about ecology, populations, native and invasive species, watersheds and other biological concepts. These are hands-on interactive lessons, and all are welcome.

Another course, “River Readings,” is offered to students in Kindergarten through second grade by the NPS every Thursday at 10:30 a.m. For one hour, students will read a short story with an NPS ranger and complete a craft and/or activity related to the story.

River cleanups occur throughout the summer. Volunteers (older children) will be outfitted by the NPS and will canoe a stretch of the river to be cleaned of garbage. Those interested should call the Zane Grey Museum at 570/685-4871 to register. The next cleanup will be Sunday, July 12.
