Physical learning not only learns physical knowledge and skills, but also cultivates the ability to analyze and solve problems in the process of experimental inquiry, and can understand scientific thoughts and spirits. This requires teachers to change the traditional teaching methods based on books and supplemented by experiments, and advocate diversified teaching methods. Therefore, in the current teaching, we must cultivate students' awareness and methods of scientific inquiry. As a leading teacher, students are encouraged to question boldly in the whole process of physics teaching; Strengthen students' guidance and stimulate innovative thinking; Only by doing experimental teaching well, enhancing students' scientific inquiry ability and optimizing teaching can we get twice the result with half the effort.
