Forty-eight students in Tally Paisuk’s sixth-grade science class at John Gregg Elementary learned a little about biology from Steubenville Catholic Central High School teacher Stephanie Vance and some of her pupils during a recent visit. The group gathered at a creek near the Bergholz school and kids learned a lesson about creek health, identifying organisms and how pollution could hinder aquatic life. Paisuk said Vance participates in a program at Fernwood State Forest where her fifth graders have attended field trips and she was invited to lead a session at the elementary school.
