物理学是一门以实验为基础的科学,物理中的许多物理规律及物理知识都来源于实验。初中物理教材中的实验有学生实验、演示实验、课后小实验,做好这些实验对培养学生的观察能力、创新能力、动手动脑能力,提高学生的综合能力有重要的作用。物理实验在物理教学中占有重要的地位,教师只要充分利用好各种实验,就能起到事半功倍的效果。这些实验能把一些抽象的物理知识具体形象地展现出来,对培养学生的学习兴趣有重要的作用。下面我 Physics is an experiment-based science. Many physical laws and physical knowledge in physics come from experiments. Experiments in junior high school physics textbooks include experimenting with students, demonstrating experiments and small experiments after class. Doing well these experiments plays an important role in cultivating students ’abilities of observation, innovation, brain activity improvement and students’ comprehensive ability. Physics experiments occupy an important position in physics teaching. As long as teachers make full use of various experiments, they can play a multiplier effect. These experiments can be a number of abstract physical knowledge concrete image of the show, to develop students interest in learning has an important role. Below me
