Scientific information has always been verified and based on practice and experience. Physics, on the other hand, expresses information about phenomena in the material world through experience. Therefore, the most effective way to check theoretical information is conducting experiments and laboratory training. In the article, special attention is paid to the main methodological approaches to the effective organization of laboratory classes, the fact that experimental demonstrations are based on scientific innovations, as well as the role of laboratory work in the formation of scientific research and practical skills in students.
