Abstract

A political-class teaching appliance relates to a teaching appliance and especially relates to the political-class teaching appliance. The political-class teaching appliance is concretely suitable to explain a quantitative change and qualitative change rule in the political class. The political-class teaching appliance comprises a parallel-bars-shaped support, a hook, a wooden strip, two concave cross bars, a counterweight barrel and counterweights. The two concave cross bars are fixedly mounted on two ends of the parallel-bars-shaped support. The wooden strip is transversely disposed on the two concave cross bars. An upper end of the hook is hung on a middle position of the wooden strip. The counterweight barrel is hung on a lower end of the hook. The counterweights are arranged in the counterweight barrel. Because the political-class teaching appliance provided by the utility model comprises the wooden strip, the hook and the counterweight barrel, by gradually increasing an amount of the counterweights, the wooden strip is broken finally and a process from quantitative change to qualitative change is presented. The teaching appliance is help to explain the rule that quantitative change causes qualitative change.
