实验是物理教学的重头戏,物理概念的建立与物理规律的发现,都以实验事实为依据。实验同时也是激发学生学习兴趣的重要手段,只有重视实验、巧用实验才能更好地激活物理课堂,激发学生学习物理的浓厚兴趣。一、通过趣味新奇的物理实验演示,激发学生的好奇心理,从而激发他们思索的欲望例如,在讲授“大气压”一节时,可在装满水的杯上用硬纸片盖住并倒过来,发现水并不流出,纸片也不下落,使学生确信大气压的存在。接着让两个学生做马德堡半球实验,使他们感觉到巨 Experiment is the highlight of physics teaching. The establishment of physical concepts and the discovery of physical laws are all based on experimental facts. At the same time, experiments are also an important means to stimulate students 'interest in learning. Only by focusing on experiments and using experiments can we better activate physics classes and stimulate students' strong interest in studying physics. For example, teach the “atmospheric pressure” section to be covered with cardboard in a water-filled cup and then On the other hand, we found that the water did not flow out and the pieces of paper did not fall, making the students confident of the existence of atmospheric pressure. Then let the two students make the Madgeburg hemispheric experiment, so that they feel huge
