Abstract
Continuity of education is ensured based on the introduction of basic physical concepts and phenomena in the sixth grade about the structure of matter. Only then will the sequence from simple to complex be maintained in education, and students' understanding and comprehension activities will develop. Such information is used when passing topics related to thermal phenomena. In particular, it is explained that the movement of molecules depends on the temperature of the body, and this connection is expressed based on the comparison of the diffusion rates in bodies with different temperatures. It is intended to teach students to think logically about the surrounding physical phenomena, including the phenomenon of the structure of matter and its essence, and equip them with the knowledge, skills and abilities related to physics necessary for their social life.
