specific content of the biophysical body, the method of in-depth description of the material, the
nature and properties of the objects in a specific course.
The topics of heat events show the most important role of heat in human life. Students
will be reminded of the age-old cartoons they have seen on television, the myths about fire
they have heard in ancient world history lessons, and the human struggle for survival in
nature. The textbook lists some of them. For example, a space rocket, an intercontinental
rocket, all ships, cars, tractors, trains, and so on. Accordingly, the study of thermal
phenomena is required in the operation, adjustment and improvement of related machines.
Information on heat sources is also provided. For example, the main source of heat on Earth is
the Sun. It is also explained that the basis of gasoline burning in the car engine is the Sun. At
the same time, it is proved that heat can be generated not only by burning something, but
also by doing something. This shows that the coin heats up when it is rubbed on the wool
material. This creates the basis for the formation of the concept of work into energy, the
transformation of energy into work.
The development of modern science and technology requires that knowledge, practice
and experience be inextricably linked. When physics is taught in isolation from production,
students do not understand why it is needed and why it is necessary to study it. It aims not
only to increase students' interest in physics, but also to strengthen their polytechnic training
by developing their technical activity, highlighting the role and importance of scientific and
technical achievements in modern production. In particular, the topics "Electric capacity",
"Capacitors", "Semiconductor devices", "Electromagnetic oscillations and waves" are given
practical attention, which is positive for the development of technical and creative abilities of
students. affects.
When students study the magnetic field of a current, they learn about the magnetic
properties of body tissues, that tissues are somewhat diamagnetic, like water, and therefore
not magnetized at all under the influence of an external magnetic field. However, there are
also paramagnetic substances, molecules, and ions in the body (there are no ferromagnetic
particles in the body). The magnetic field affects them and affects many life processes, such as
the condition of cells, tissue respiration, the human nervous system, and so on. Also keep in
mind that the lower the resistance of a conductor, the lower the resistance and the higher the
current. If left unmanaged, they can be left astray and lose the right path.
Another way to engage students in the process of teaching physics is to explain some
physical experiments during the lesson based on physical processes in nature. Properly
organized, demonstrated and interpreted experiments in physics allow the student not only to
learn the structure and operation of equipment, but also to observe the laws in them. Physical
education also stimulates students' interest in the subject. Demonstrations show physical
concepts, physical quantities, and the ability to measure them. They are then formed,
developed, and deepened in laboratory work and problem solving. At the beginning of a
physics class, you need to demonstrate experiments that, while simple, are a starting point.
What they see will be the basis for later explanations. The dimensions of the physical
quantities (length, time, mass, pressure, temperature, etc.) are determined and the
quantitative and qualitative relationships between them (pressure of the liquid at the bottom
of the vessel) are indicated. The process of teaching demonstration experiments is to
demonstrate the practical application of the laws of physics. They show a complex process in
which several physical laws are used in experiments. Of course, such experiments are not
very common, and are conducted when students have a certain amount of knowledge.
Demonstrations should not be large. The experience should be given as an aid to the teacher's
