物理小实验是指那些材料易得(多是日常用品)、简便易做、趣味性浓、形象生动、效、果明显的物理实验。它在中学物理教学中的作用我体会如下: 一、物理小实验能加深理解和巩固掌握所学的物理知识物理小实验在初中物理课本中安排的较多,第一册就安排了十个。如在学生分组实验“物体浮在液面的条件”之后,安排了一个“鸡蛋浮沉”的小实验。学生在课后都有条件做这个实验。学生如果做了这个小实验,不仅能激发他们的学习兴趣,同时又巩固了课堂上所学的知识,而且还加深了对物体浮沉原理的理解,因为这个小实验是从另一个角度(即从液体的密度改变的情况下)来研究“物体浮在 Physical experiment is that those materials are easy to get (mostly daily necessities), easy to do, interesting and rich, vivid, effective, obvious physical experiment. Its role in secondary school physics teaching I understand as follows: First, the physical experiment can deepen the understanding and consolidation Master the knowledge of physics Physics experiments in the junior high school physics textbooks arranged more, the first one arranged for ten. As in the student group experiment “object floating on the surface conditions,” arranged a “egg floating” experiment. Students have the conditions to do this experiment after class. Students who do this small experiment not only stimulate their interest in learning but also reinforce what they have learned in class and deepen their understanding of the principle of object floating because the experiment is from another perspective, Liquid density changes) to study "the object floats
