With the Ice Melting Blocks thermodynamics demonstration, decisively demonstrate heat conductivity in less than 30 seconds. An unmistakable discrepant event that is sure to clarify the difference between a conductor and an insulator.
Decisively demonstrate heat conductivity in less than 30 seconds! Touch the identical-looking blocks. One feels cold to the touch, the other feels warm. Place an ice cube on each block, and watch as one ice cube rapidly melts. Which block melts the ice cube—“cold” or “warm?” Students will be amazed when they see the “cold” block melting the ice cube remarkably faster than the “warm” block. How is this possible? The “cold” block is a heat conductor—it easily transfers heat energy. The “warm” block is an insulator. An unmistakable discrepant event that is sure to clarify the difference between a heat conductor and a heat insulator. Instructions provided. Block dimensions: 10 cm × 10 cm.
