The Martha Canfield Library invites children ages 5 to 10 to a "Candy Bar Lab" on Thursday, July 12 at 2:00pm. Children will learn about rock classification. They will then experiment with a candy bar lab to see how a variety of rocks are formed. Led by science teacher Andrew Jaffee, this program is free and open to the public.
