Everyone knows that applying heat to an object increases its temperature. But what really is going on when the temperature of an object increases? 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 with wooden handles to protect hands from the heat, making it a perfect hands-on experience for students.
