著名物理学家麦克斯韦说过:“一项演示实验使用的器材越简单,学生就越熟悉,就越想彻底地获得所验证的结果,这种实验的教育价值往往与仪器复杂程度成反比。”实验是物理教学内容之一,有些实验因为本身目的和功能的需求,必须由专制仪器完成,而更多实验或学生活动不需要专用器材,可以用生活中的物品取代,这类器材被称之为“生活化”器材。用生活化器材做实验,具有简便、直观、 The well-known physicist Maxwell said: “The simpler the equipment used in a demonstration experiment, the more familiar the student is, and the more complete the desired result is to be verified. The educational value of such an experiment is often inversely proportional to the complexity of the instrument. ”Experiment is one of the physical teaching content, some experiments because of their own purpose and function needs, must be completed by authoritarian equipment, and more experiments or student activities do not need special equipment, you can use the goods in life, such equipment was Call it “living” equipment. Experiment with living equipment, with a simple, intuitive,
