The main thematic areas of the celebration of the new International Year are discussed. The role of the journal “Chemistry at school” as a unique collection of didactic materials suitable for practical implementation in the framework of the International Year of Fruits and Vegetables is noted.

The article deals with modern storage technologies and methods of chemical processing of vegetables and fruits.

The article presents various classifications of computer presentations and describes them as a tool for implementing the educational process. The role of educational computer presentations is revealed and it is shown that in the modern educational process they are designed to perform not only informational and illustrative, but also organizational and managerial functions. The selection criteria for training chemical content for computer-based presentations are discussed. Examples of two presentation slides containing declarative and procedural knowledge are given, methods for including content in the educational process are shown, and a methodological analysis of the techniques used is made.

Training session on the topic "Basic concepts of chemistry of high-molecular compounds. Classification and methods of polymer synthesis. Polyethylene, polypropylene, polyvinyl chloride: composition, preparation, properties, application" is conducted in the form of a combined lesson, the effectiveness of which depends on a clear understanding of what students need to be taught and how to rationally organize their activities.

The article discloses the meaning of the concept of “edutainment”. Edutainment, the inclusion of entertaining elements in the learning process, has significant potential to increase motivation to study chemistry.

The article discusses the features of case and TIPS technologies and their potential in the development of students’ meta-subject skills in chemistry lessons. Examples of the structure and content of the case and tasks using TIPS techniques for lessons in the section «Metals» are given.

Through the definite example the article depicts the basic knowledge formulated in the form of inferences which students use to find a sequence of actions and ways of solving complex problems.

The article presents tests for the current monitoring of knowledge on the topic “The rate of a chemical reaction”. Students will analyze graphs in the process of solving test tasks.

The article reveals the specifics of teaching first-year students. The authors highlight the features of building professional relations between teachers and students, as well as provide recommendations for creating a working environment in the classroom.

As a result of the conducted research, it was established that students’ prediction abilities are successfully formed thruogh the systematic use of prediction techniques.

The memoirs by the Nobel Prize laureate in chemistry Nikolai N. Semenov about his years of study in the Volsk and Samara real schools, his early passion for Chemistry and Physics are commented on. Thanks to the teacher of the Samara School, V. I. Karmilov, young Nikolai Semenov strengthened his desire to devote his life to science. Friendship and mutual assistance between N. N. Semenov and V. I. Karmilov persisted for many years. From the end of the 1930s to the end of his life, V. I. Karmilov headed the Department of Physics at the Perm Medical Institute, where he created the first magnetic therapy devices.

A relay race of Natural Sciences is organized as a long-term (school week) team competition between classes, held in the form of an educational game. The main goals are to motivate students to study Natural Sciences, develop teamwork and interpersonal communication skills, and stimulate creative activity.

Students’ research activities in the framework of the educational subject “chemistry”, as a rule, involves conducting laboratory research, however, due to various circumstances, not all students have access to a real chemical experiment. The article describes the approaches to the implementation of students’ research activities based on theoretical research, implying the analysis of information from various sources, its generalization and systematization.

The article is devoted to the research work of 11th grade students related to the study of the sorption activity of various enterosorbents.
