在中学物理《物质的分子运动》一节中,为了证实分子的无规则运动,需通过实验,观察“布朗运动”这一现象.而根据教学参考资料上所提供的方法去做,实验效果不佳.为此,我们进行了探索性的试验——用生物显微镜观察“布朗运动”.通过多次反复试验,获得了成功.学生通过显微镜直接观察,对“布朗运动”有了较深刻的理解.具体做法如下: In the section “Molecular Movement of Matter” in the middle school physics, in order to confirm the random movement of the molecules, it is necessary to observe the phenomenon of “Brown movement” through experiments. According to the methods provided in teaching reference materials, the experimental results are not effective. For this purpose, we conducted an exploratory experiment—observing the “Brown movement” with a biological microscope. Through repeated trials, we achieved success. Students observed directly through the microscope and had a deeper understanding of the “Brown movement”. The specific approach is as follows:
