Discovering Black's Nook
This secluded pond, a favorite spot for nature lovers and dogs, was the subject of investigations during a program that gave information about the quality of its water. Barbara Strell (left photo) used a tool to harvest aquatic plants; Susan Agger (center photo in yellow hat) used a sieve to collect macro-organisms; and Squizzle Plekavich (right photo) used a special net to collect algae and zooplankton. Later, indoors, the participants examined the specimens by eye and microscope, and identified them using guides and keys. This Cambridge Science Festival program was co-sponsored by Friends of Fresh Pond Reservation
