The structure of substances in the course of chemistry of the secondary school and the method of teaching initial concepts of structure

This article is devoted to improving the quality of education using modern methods of teaching the first concepts of the structure of substances in the chemistry course of secondary school. The chemistry course also teaches that the properties of substances are related to their structure and the formation of these properties in students. Research objectives: to give the basic concepts of the structure of substances in the course of chemistry and to familiarize students with the initial laws. Research materials and methods: lesson planning of the theme of the structure of substances, drawing up a diagram of the structure of substances and their physical properties. Research results: when creating a diagram of the history of substances, students used the skills of comparison and inference, which ensure the activation of mental activity. Conclusions: the first understandings about two types of matter (molecular and non-molecular structure) are firmly acquired by students in the following topics and are easily deepened and expanded.
