The Middle School Interact Club, from the Independent Day School in Middlefield, is once again joining the Rotary Club’s effort to help eradicate polio.The Interact Club, which includes sixth, seventh, and eighth graders, runs the Coyote Cave, a school store, to raise money for the eradication project. In addition, students have the option of donating an extra dollar at their dances and having their pinkies painted purple. Infants’ pinkies are dyed purple after they receive a dose of the polio vaccine. The student club is also planning a Polio Awareness Day. In the past three years, the club has donated over $2000 to the cause. This year, the Interact Club will be expanding its service learning efforts to include a variety of projects to help others in need.
