More Information
Summary:The utility model relates to a conductor heat-conducting rapid-slow teaching tool, and in particular relates to a metal heat-conducting demonstration tool, which comprises a transformer, a metal rod, a luminous diode and a temperature-control switch, and is characterized in that the demonstration tool also comprises a low-voltage heater, wherein, a plurality of metal rods that are made of the same material is arranged inside the low-voltage heater, and each metal rod is respectively serially connected with the temperature-control switch, the luminous diode and a battery through a conducting wire to form a serial-connection circuit. The luminous diode is connected with a buzzer in parallelism. The luminous diode is connected with a music box in parallelism. Students can distinguish the heat conducting speed of metal that is made of different materials according to different music; students also can judge the heat conducting speed of metal that is made of different materials through the light of the luminous di
