Information on the Congress of representatives of associations of chemistry teachers held in Moscow on July 19, 2016 is provided.

The article deals with the main categories of substances found in peppers and other "hot" plants. The structure and properties of the vanilloid receptor are considered. It is shown that TRPV1-receptor is a critical integrator of different pain stimuli. In this connection, it is regarded as a promising therapeutic target in the treatment of pain conditions. Thus, the search for modulators of TRPV1-receptor is one of the most important general scientific problems.

Tendencies of development of scientific and technical progress according to the new sixth technological way for training of pupils for professions of the future are presented. The concept of the "clever" cities, necessary experts and their competences are discussed. The scenario of a role-play "The eco-friendly clever city – the city of the future" has been designed for vocational guidance of seniors. The role-play can be used in the class as well as in extracurricular activities, in the system of additional education of children, and in organizing team work while preparing and holding the Olympiads, competitions, festivals.

The authors offer their own experiences of conducting an integrated lesson on the topic: "Еcology of the soul and ecology of nature". Due attention is given to methodical aspects of the problem. It is shown that such form of training has a beneficial effect on the formation of creative activity of pupils, allowing them to fulfill themselves.

Experience shows that active learning in the chemistry classes increases students' interest in the subject, ensures their independence, better understanding of the material studied, promotes students’ creativity.

The article deals with issues related to the experience of using "startup experiment" in schools of Kyrgyzstan. The aim of the article is to analyze the lessons and teachers' reports on a "startup experiment", revealing their characteristics and drawbacks in their conducting. The paper describes the structure and features of the proposed format of the lesson, its goals, methods and techniques to achieve the results of the lesson. It is described in detail. Actions of the participants of the educational process in successive steps are described in detail. Conclusions and recommendations of the author are certain suggestions for improvement of the described method of teaching, including step-by-step students’ work.

The article presents methodological approaches to forming research thinking of modern children through organizing the Summer school of young chemists. It is shown that the level of the research thinking of modern children depends on the creation of special informational and educational environment and the use of technology immersion in the process of learning, implementing the idea of integration of children’s general and additional education.

The article deals with the formation of universal educational activities in the project activities. The project "Determination of the qualitative composition of gasoline of various brands" for 10-graders is described. The criterion for choosing the theme is the preliminary vocational guidance monitoring. The types of learning actions, emerging at different stages of project activities are discussed.

The article is devoted to comparison as one of the most important logical methods. By comparing students can find the essential features of similarity and difference between two concepts. The author shows how it is possible to use the method of comparison in chemistry classes with the help of didactic tools of knowledge developed in the method of dialectic training.

In the article the author considers the laboratory chemical experiment for the detection of amino acids in food products. The proposed experiments are quite simple techniques, therefore, can be used by teachers of chemistry and biology in the classroom and in extracurricular activities.

In this work the determination of pH of 14 items of "iced tea", 6 items of carbonated drinks containing natural juice, 10 items of traditional soft drinks, 13 items of purified drinking water and mineral water was carried out by using various types of pH test strips. Drinks with the lowest and highest pH were revealed. As a result of reviewing scientific literature, it was concluded that nowadays there is no objective scientific data indicating the ability of the carbonated beverages to cause chronic diseases due to its pH.

Theatrical performance is devoted to the 155th anniversary of the creation of the theory of chemical structure of organic compounds by A.M.Butlerov. The main and important conditions of increasing efficiency of teaching at present is not only maintaining students ' motivation to study the subject at the appropriate level, but also the systematic inclusion of students in the independent research activity and development of cognitive activity. The implementation of these directions in the learning process makes use of the principle of historicism, which not only promotes the acquisition of students ' knowledge about the subject, formation of their cognitive activity, but also allows them to be proud of their Motherland, and to develop careful attitude to historical and cultural heritage of our country. The scenario of extracurricular activities for 9–11-graders is dedicated to the 155th anniversary of the Butlerov theory of chemical structure. The purpose of the event is to acquaint students with the life of A. M. Butlerov and his contribution to the development of organic chemistry.

The material concerning the early career of the prominent chemist Vladimir Ipatiev is given. A man without classical University chemical education, he managed to achieve the highest achievements and success. In fact he was self-educated, therefore, it is useful for students to follow his path to the top of chemical science. In 2017 the world community of chemists will celebrate Ipatiev’s 150th anniversary.
