物理学科活动课由于没有现成的课本、课件，需要教师在实践中不断探索。我根据物理学科的知识特点和学生实际情况，从三个方面确定物理活动课的内容。第一，对某一知识的横向拓展和纵向加深，体现活动课内容的延展性和层次性。如学完声现象后，设计了《有趣发声》活动课，以发 Physical activity classes because there is no ready-made textbooks, courseware, teachers need to continue to explore in practice. According to the characteristics of physics and students' actual situation, I determine the content of physical activity class from three aspects. First, horizontal extension and vertical deepening of certain knowledge reflect the extensibility and hierarchy of the content of activity class. If you finish the sound phenomenon, designed a “funny voice” activities to send
