Without exaggeration, the quality of knowledge and the practical training of our students in physics correlates with the setup of a physical experiment. The quality of most classes relies to a large extent on how well an experiment has been prepared for and carried out. The most effective studying method is the so-called heuristic approach when students largely make their own conclusions based on the results obtained from a learning experiment (demonstration, frontal, experimental tasks, etc.).

If the task is naturally associated with the study material, learners become aware that knowledge is essential for any human-being, including themselves, to exist.
