在做好课堂演示实验和学生分组实验的基础上,联系教学实际布置一些学生力所能及、简单易行的课外实验,特别是布置一些学生能在家里进行的趣味实验,可以激发学生学习物理的兴趣,促使学生自觉地观察现象,探索知识,从而提高他们分析问题和解决问题的能力.下面介绍两个有趣的实验.一、用兵乓球做的实验在讲完流体的流速和压强的关系以后,我给学生布 Based on classroom demonstration experiments and student grouping experiments, linking teaching to the actual arrangement of some students outside of their ability and simple and easy extracurricular experiments, in particular the arrangement of some students can carry out fun experiments at home, can stimulate students to learn physics interest, Students are motivated to observe phenomena and explore knowledge in order to improve their ability to analyze problems and solve problems. Here are two interesting experiments. First, experimenting with table tennis balls after talking about the relationship between fluid velocity and pressure, I give students cloth
