A group of second and third graders enjoys film strip viewers, books, unusual rocks, and records (heard through individual head phones) in the library and instructional materials room of the new Thurston Elementary School. Children will be able to use the materials independently, according to Thurston principal Mrs. Josephine Brokaw. Among the other features of the newly opened school are an art room with a potters wheel, kiln and woodworking table, and a combination room and individual work room within each classroom. Thurston was opened this fall.
