Abstract: Aim. To present the possibility of using the content of laboratory works carried out within the framework of the academic disciplines of chemical training to demonstrate the effects of intermolecular interactions underlying the formation of supramolecular structures in order to expand the future chemistry teachers’ understanding of ideas about supramolecular chemistry.Methodology. To achieve the set goal, theoretical and practical methods were used: analysis and synthesis of methodological literature; testing of a chemical laboratory experiment.Results. The topics of the academic disciplines of the bachelor’s degree program “Pedagogical education, profile “Biology. Chemistry” have been selected, the content of which may include questions that reveal general ideas about the formation, structural features and functioning of supramolecular systems. Examples of laboratory work are given, the implementation of which allows demonstrating the manifestations of individual types of intermolecular interactions as the basis for the existence of supramolecular systems.Theoretical and/or practical significance. The authors selected the examples of laboratory works demonstrating the manifestations of individual types of intermolecular interactions (hydrogen bonds, ion-dipole, dipole-dipole) on the basis of which the formation of molecular ensembles occurs, causing changes in the properties of the system. According to the authors, the implementation of the presented laboratory works will contribute to the development of future chemistry teachers’ basic ideas about the features of the structure and functioning of supramolecular systems, and the formation of supramolecular chemistry key concepts for the further transfer of the acquired knowledge to the information space of school chemistry education. The possibility of implementing the proposed laboratory works within the framework of the school chemistry course both in lessons and in extracurricular work when organizing project and research activities can allow students to get acquainted with the issues of supramolecular chemistry as one of the largest areas of development of chemical science at the present stage.Conclusions. The influence of the role of performing the laboratory work options proposed in the article on the formation of students’ ideas about the chemistry of supramolecular systems requires further experimental verification. Substantiation of the practical results obtained during the performance of these laboratory works, from the position of the manifestation of various options for intermolecular interactions, can serve as a basis for developing ideas about the structural organization of supramolecular systems and their functioning both at the level of chemical reactions and at the level of the work of molecular ensembles in the process of vital activity of highly organized biological systems.
