Physics is a science that reveals to us the mysterious and multifaceted world of natural phenomena. An open lesson on the topic "Current in different media. Laws of electrolysis. Electrical conductivity of semiconductors. Applications of semiconductor devices" conducted by physics and astronomy teacher Iryna Yuriivna Veremchuk in the 11th IP group became a vivid example of how complex laws of nature can be explained simply, easily and fascinatingly.
The class began with an intriguing question: “Why do conductors behave differently under electric current?” The students immediately became interested in the topic. After all, electricity is not just a light bulb that lights up or a phone that charges. It is a whole world of invisible processes that affect our lives.
During the lesson, the teacher did not just explain the material, but immersed the students in a real study. They considered how electric current passes through metals, liquids, gases, semiconductors, and even a vacuum. A simple example — a wire that conducts current due to the movement of free electrons — became the starting point for explaining complex physical phenomena.
Special emphasis was placed on the practical significance of current in various environments. As the teacher explained, metals are the basis of electrical networks, liquids and electrolytes are used in batteries, gases are used in fluorescent lamps, and semiconductors are the basis of microcircuits and modern electronics.
Experiments were not left out either. The demonstration of the conductivity of different media caused real enthusiasm among the students. The experiment on the passage of current in a solution of copper sulfate made the greatest impression, the light bulb lit up, causing smiles and joy from what all the participants saw. Answers to the question “Why does it work?” became a real intellectual adventure. Watching a short film about the life and scientific discoveries of Michael Faraday allowed us to see the world of physics through the eyes of scientists.
The session ended with a reflection, where everyone had the opportunity to express their thoughts and emotions. Many noted that the topic, which seemed complicated, became understandable and fascinating.
The lesson “Electric Current in Different Environments” is an example of how learning can be lively, inspiring, and one that awakens interest in learning about the world.
The open class was attended by Lyudmila BALDYCH, Deputy Director for Academic Affairs; Valeriy HUMENYUK, Head of the Department of General Education; Yulia YUKHYMCHUK, Tetyana HRYTSIK, and Ihor KAPITULA, teachers of the cyclical commission of general education disciplines.
