In education there are no casual people. Familiarizing with this profession is determined neither by chance and momentary interest nor by pragmatism. The choice of a teacher’s profession is a choice of destiny, an investment into the future, and a conscious responsibility.

The laboratory photoreactor has been designed, the preliminary tests have been carried out to show that the UF reduces phosphor-organic pesticides levels in juice (extract) and increases ecological safety of a target product. Technological parameters of processing are experimentally established: UF-radiation impulse duration 10-6-10-3 with, the range of wave length of 190-260 nm, frequency 1-1,3 Hz, processing time 20 min.

The article presents the experience of the author on the implementation of a blended learning technology model called the Lab-Rotation model in secondary school. The model is presented as an effective method for the organization of inclusive education, which takes into account the capabilities and needs of students with different levels of cognitive abilities. The article sets out the basic principles of the organization of the work based on the Lab-Rotation model in classroom; also the article presents an example of lesson planning. The article also shows the role of a distance support system for school course when using the Lab-Rotation model and an example of the organization of a distance platform based on Moodle.

Integrity of a lesson, his logics is set by its leading objective which is connected with the basic element of an educational process. This element unambiguously defines the type of a lesson. The system of lessons of different types has to provide perception, understanding, fixing and application of knowledge and learning actions in practice. Authors offer the typology of lessons built according to the FSES requirements and taking into account the Russian school traditions.

In this article the author tells about his favorite lesson in chemistry in the 10th form. The author shows methodology for the lesson, pupils' work and results of cooperation.

In this article you can find the materials for students’ preparation for task A25 at Russian State Exam. There is given the method of revising the topic “Chemistry Productions”. There are texts for revising chemistry productions and examples of text sums.

When solving computational problems quantitative (mole, mass or volume) the relationship of the substances entering into the reaction and the resulting reaction should be considered. This information can be obtained by referring to chemical formulas. It can be used by pupils or students in solving all types of computational problems. This eliminates the need to "train" them to the solutions of the model calculations, which we believe to be ineffective formality.

To provide disclosure of intellectual potential of the school student in the conditions of introduction of Federal State Standard of Basic General Education, professors of chemistry department of Chelyabinsk State Pedagogical University worked out instructive cards for laboratory experiment which can be used both at lessons, and in extracurricular work.

The article deals with the essence of the notion of "integrated safety", «environmental safety», «chemical safety», the peculiarities of the formation of the bases of the chemical and environmental safety at the chemistry lessons.

The article is concerned with anaerobic decomposition of carbohydrates – glycolysis and glycogenolysis. The offered experiments can be used by the teacher of chemistry, biology, ecology at the lessons and extracurricular activities.

The history of the chemistry of organic nitro compounds in our country until the beginning of the XX century was considered. Significant role in the development of this branch of science in our country was played by D. I. Mendeleev, N. N. Zinin, V. F. Petrushevskiy, S. P. Vukolov.
