Experiment:
In the experiment, first turn on the switch of the small fan. Then fill one cup with half a cup of hot water, and another cup with half a cup of cold or ice water.
Insert the two aluminum plate feet of the experimenter into the cup, and the two aluminum plates conduct heat and begin to form a temperature difference. When the temperature difference between them is greater than 12°C, the current generated is enough to turn the small fan.
The greater the temperature difference, the greater the current generated. (Note that the aluminum plate with plastic screw heads is placed in the cold water cup, and the other side of the aluminum plate is placed in the hot water cup. If it is wrongly placed, it will affect the experimental effect)

Describe:
In teaching, students can experiment with the principle that temperature difference produces current and current produces temperature difference.
It consists of two aluminum plates, with a cooling plate in the middle, a small fan and two terminals.
