GROTON -- Due to last week's storm, the Nashua River Watershed Association rescheduled "The Science of Rivers and Water in Winter," a Science Saturday program for 7- to 11-year-olds, to now be held this Saturday, Feb. 16, from 1 to 2:30 p.m.

There is still a chance to register your child to join us in our investigation of water through both indoor and outdoor experiments, including a visit to the Nashua River. We'll also explore where river animals go in the winter and how they survive the cold and ice.

The program takes place at the NRWA River Resource Center at 592 Main St. Science Saturday costs $25 and registration is required. To register contact Mary Marro, NRWA Environmental Education Director, at 978-448-0299, or email MaryM@NashuaRiverWatershed.org. The NRWA is a nonprofit environmental organization that depends on memberships for support.
