中学物理的学习中,密度的测量是学生学习的一大难点,尤其在物质密度的测量实验中给定的实验器材有时有天平和量筒,有时两个中只有一个,有时两个都没有,那么学生在遇到这些问题时怎样解决,我觉得有两种方案:(1)天平和量筒的组合,(2)天平(弹簧测力计)和量筒(刻度尺中)的任意一个和其他工具的组合,下面通过一些例题来介绍这两种方案,希望大家有所收获.
Middle school physics study, the measurement of density is a major difficulty for students to learn, especially in the measurement of material density experiments given the sometimes balance and graduated cylinder, and sometimes only one of the two, and sometimes two are not, then I think there are two options for students to deal with these problems: (1) the combination of balance and graduated cylinder (2) the balance (spring dynamometer) and any one of the graduated cylinder (graduated scale) and other tools Combination of the following examples to introduce some of these two programs, I hope everyone gains.
