物理学的研究是以观察和实验为基础的。学生实验和教师的演习试验均是中学物理教学的重要组成部分。通过实验能让学生建立物理概念和了解物理规律,是理解和掌握物理知识不可缺少的环节,还能培养学生的观察能力、思维能力和创新能 The study of physics is based on observation and experimentation. Student experiments and teacher exercises are all important components of high school physics teaching. Through experiments that enable students to establish the concept of physics and understand the laws of physics is an essential part of understanding and mastering physical knowledge, but also to develop students’ ability of observation, thinking and innovation
