物理中有许多趣味性实验,它们不仅能够调动学生的学习兴趣,而且可以让学生更深入地理解物理知识,但是在实验演示过程中,学生往往只被表面现象所吸引,而对实验原理一知半解。因此,为了让学生从趣味性实验中学到更多知识,教师可以根据实验实物制作课件,然后根 There are many interesting experiments in physics. They not only can arouse students’ interest in learning, but also enable students to understand physics more deeply. However, in the course of experimental demonstration, students are often attracted by superficial phenomena and have little knowledge of experimental principles. Therefore, in order for students to learn more from interesting experiments, teachers can create courseware based on the experiment and then
