Introduce students to the concepts of expansion and contraction using the ball and ring. The unit demonstrates the expansion of metal when heated and its contraction when cooled. When either the ball or ring is heated, the ball will not pass through the ring. When cooled, however, the ball will pass through the ring freely. The ball and ring are mounted on insulated wooden handles to protect hands from the heat. Retail version.
