The experiment is the basis of physics and is the standard for testing physical theory. In the classroom teaching where students establish a complete physical concept and derive the correct physical laws, the experiment is the most active and most vital part. Demonstration experiment is an experiment that is accompanied by the teacher to manipulate the teaching content.
