Types of extracurricular activities in biology. Lecture extracurricular, extracurricular and extracurricular work in biology

Grounds for the allocation of forms of extracurricular work.

The secondary school has accumulated great experience extracurricular work in biology, which is reflected in special methodological publications, as well as in the chapters of general and particular methods of teaching biology. In some of them, along with the disclosure of the content and organization of extracurricular work, its forms and types are considered.

The circle of young naturalists is generally recognized as the main form of extracurricular work. Differences are observed in the selection of other forms. Along with the circle, the forms of extracurricular work include, for example, extracurricular reading. The most acceptable selection of forms was proposed by N. M. Verzilin. In the book "General Methods of Teaching Biology" (M., Education, 1974), the author classifies individual, group and mass classes as forms of extracurricular work. At the same time, the circle of young naturalists in the proposed system is presented as a type of group form of extracurricular activities.

When identifying forms of extracurricular work, one should proceed both from the number of students participating in extracurricular work, and from the principle of systematic or episodic conduct of it. Taking into account the above, it would be more correct to single out 4 forms of extracurricular work in biology:

  • 1. Individual lessons;
  • 2. Group episodic classes;
  • 3. circle classes;
  • 4. mass naturalistic events.

It is hardly expedient to single out extra-curricular reading or extra-curricular observations, the production of visual aids and other work carried out by students on the basis of their voluntariness, as independent forms, since it is used both in individual and in episodic group, circle and mass forms of classes.

Characteristics of the forms of extracurricular work in biology.

An individual form of extracurricular work takes place in all schools. Trying to satisfy the needs of individual students who are interested in biology, the teacher invites them to read one or another popular science book, make observations in nature, make a visual aid, and select material for the stand. Sometimes, while satisfying the curiosity of individual students, the teacher does not set any goal for himself, does not direct this extracurricular work in a certain direction, and does not even consider that he is conducting it. This pattern is often observed among teachers who do not have sufficient work experience.

Experienced teachers clarify the biological interests of schoolchildren, constantly keep them in their field of vision, set themselves the task of developing their interests in biology, select appropriate individual lessons for this, gradually complicating and expanding their content. Some students create their own home wildlife corners. The teacher gives instructions to such students for setting up experiments at home. Individual extracurricular activities are essentially a voluntary variety of home and extracurricular activities.

The most common types of individual extracurricular work include experiments and observations on plants and animals in nature, in an educational experimental site, in a corner of wildlife, making artificial nests and observing their settlement, self-observation, making visual aids, preparing reports, abstracts, and much more. other.

Group episodic classes are usually organized by the teacher in connection with the preparation and holding of school mass events, for example, school biological Olympiad, Biology Week, Health Week, Bird Day holiday. To carry out such work, the teacher selects a group of students who are interested in biology, instructs them to select certain material, publish a thematic wall newspaper, prepare and conduct reports, art numbers for the holiday. Usually, after the completion of any mass event, the work of the episodic group stops. To conduct another mass event, the teacher attracts students from the previous episodic group or creates a new one.

Occasional group extracurricular work is also organized in connection with the desire of the teacher to study the wildlife of his region more deeply, for example, to make an inventory of tree and shrub vegetation, to find out the species composition of birds inhabiting places near water bodies; to study the daily activity of animals of various species, the "biological clock" of plants. The need to organize such episodic group work usually arises when there is no circle of young naturalists at school.

The circle of young naturalists is the main form of extracurricular work. Unlike the episodic naturalistic group, circle classes unite schoolchildren who systematically perform them throughout the year and even several years. The composition of the circle is usually stable and may include both students of the same class or parallel classes, as well as students who differ in years of study. Often, students are united in a circle not by age and not by the level of preparedness, but by inclinations, dedication to the youth business.

The naturalistic circle is characterized by such types of work as experiments and observations (in a natural setting, in an educational and experimental area, in the corners of wildlife); excursions in nature and in agricultural production; participation in nature conservation; publication of handwritten journals; production of visual aids. The circle of young naturalists is the organizer of all extra-curricular mass biological events.

In the practice of schools there are various naturalistic circles. Some of them include a variety of biological subjects of classes, others are rather narrow in terms of the content of the work. So, along with circles of young botanists or experienced crop growers, there are often circles of indoor floriculture or even circles of cactus growers.

When determining the content of the work of the circle, it is most expedient to proceed from the fact that every student who is interested in biology must have versatile knowledge about wildlife. Therefore, narrow specialization at the very beginning of circle work is premature. The practice of many teachers shows that circle work at school is more successful if the circle members, who first become familiar with various possible problems, then consciously choose for themselves a direction that is more in line with their interests in the course of classes.

Mass naturalistic events are organized on the initiative of a biology teacher and are held with the active participation of a circle of young naturalists, school student activists, school administration, and subject teachers. Plans for mass events are approved pedagogical councils schools.

A large number of students are involved in mass work - parallel classes, the whole school. It is characterized by a socially useful orientation. Usually at school they hold such types mass work like biology olympiads; thematic evenings dedicated to Health Day, Birds Day, Garden Week, Forest Week; campaigns for planting trees and shrubs, collecting seeds and other food for winter feeding of birds; making and hanging bird nests.

All of the above forms and types of extracurricular work in biology are interconnected and complement each other. In the emergence and development of the relationship between them, a certain pedagogical pattern is observed. Interest in working with living organisms usually arises in schoolchildren when performing individual tasks. Having successfully completed certain tasks of the teacher, they usually ask for additional extracurricular work. If there are several such students in the class, the teacher unites them into temporary naturalistic groups, and later into circles of young naturalists, working in which they take an active part in the preparation and conduct of mass naturalistic events.

The use in the lessons of the results of individual, episodic group and circle work (for example, demonstrations of manufactured manuals, reports on observations made, reports prepared on the basis of extracurricular reading) contribute to the involvement in extracurricular work of students who have not previously shown due interest in it. Often, some schoolchildren who at first took a passive part in mass extracurricular work on landscaping the school territory, making bird houses, as listeners, later become either young naturalists or are actively involved in individual or group episodic work carried out on the instructions of the teacher.

In schools where extracurricular work in biology is well established, all its existing forms take place. Conducting public events is necessarily associated with both individual and group episodic and circle work of students.

Interconnected and complement each other and types of extracurricular activities. So, in the process of conducting observations and experiments on plants and animals, or self-observations, schoolchildren have various questions, the answers to which they find in popular science and scientific literature, and then after working with it (extracurricular reading), they again turn to experiments and observations to clarify, visibly reinforce the knowledge gained from books.

A study of the experience of schools shows that extracurricular work in biology is carried out in all its forms. Almost every school has a naturalistic circle, various public events individual and group episodic lessons are organized. However, extracurricular work often comes down to organizing exhibitions of students' summer work, holding olympiads, Biology Week, and Bird Day. The rest of the time, care is usually taken indoor plants, issue of bulletins based on the use of materials from popular science periodicals, "Hours of Entertaining Biology" are held. Meanwhile, the specificity of extracurricular work in biology, the science that studies living things, is associated with such types of work that include independent research of schoolchildren, put them in the position of pioneers, and arouse real interest in the knowledge of nature.

The changes taking place in society determine new requirements for the national education system. Successful self-realization of the individual during the period of study and after its completion, its socialization in society, active adaptation in the labor market, are the most important task of the educational process.

In system schooling, the biological cycle of disciplines occupies a special place, makes a significant contribution to the comprehensive development of the individual, forms a modern natural-science picture of the world in the younger generation. The teaching of biological disciplines gives more and more positive educational results if the educational process is connected with extracurricular activities, the importance of which in the general system of education and upbringing is growing today. The organization of extracurricular work on the biological cycle of disciplines should be an integral part of the educational and cognitive work of students.

Today it is already difficult to agree with the classics of the methodology (N. M. Verzilin, D. I. Traitak and others) that extracurricular work contributes to the assimilation of knowledge by students and enhances their developmental function. On the present stage the paradigm of biological education has changed, new goals and objectives are facing biological education, the main goal of which is the education of biologically and environmentally literate people.

The teaching and upbringing tasks of the school biology course are most fully resolved on the basis of the close connection between the class-lesson teaching system and the extracurricular work of students. Knowledge and skills in biology acquired by students in the classroom, laboratory classes, excursions and other forms academic work, find in extracurricular activities a significant deepening, expansion and awareness, which have a great influence on the overall increase in their interest in the subject.

The success of extracurricular work in biology is largely related to its content and organization. Extracurricular activities should arouse interest among schoolchildren, captivate them with various activities. The formation of students' cognitive interests in the process of extracurricular activities is a holistic, complex, multifaceted and lengthy process, which becomes more complicated at each stage of schoolchildren's activities. B. Z. Vulfov and M. M. Potashnik believe that the main features of the organization of extracurricular activities should be as follows:

  1. Unlike training sessions extracurricular activities are organized and conducted on a voluntary basis. This is its first feature. Students, depending on their interests and inclinations, independently enroll in various circles, take part in mass and individual work outside of school hours at will. Consequently, voluntariness means, first of all, the free choice of types of extracurricular activities. The task of the teacher is to involve all students without exception in extracurricular activities. This should be done, of course, without coercion.
  2. The organization of extracurricular activities is that it not bound by compulsory programs. Its content and forms depend mainly on the interests and needs of students, on local conditions. The programs of the circles are exemplary, indicative. On the basis of these programs and instructive guidelines, work plans are drawn up, taking into account the specific conditions and wishes of students. This allows you to make the content of extracurricular activities more flexible, meeting the interests and needs of students.
  3. Extracurricular work covers students of all ages. A mixed-age composition cannot serve as an obstacle in the organization and conduct of extracurricular activities. On the contrary, by bringing together students from different classes, extra-curricular activities contribute to the rallying of the general school team, favorable conditions are created for the patronage of the elders over the younger ones, for the development of comradely assistance.
  4. Extracurricular activities are dominated by self-study . Undoubtedly, independent work students need to be directed to the teacher, but unlike training sessions, it is mainly the students themselves who organize it. The older the students, the more fully and multilaterally their initiative and independence are manifested. They act not only as participants in various circles, club-type associations, but also as active organizers of extracurricular activities.
  5. The peculiarity of extracurricular work in modern conditions lies in the fact that now it takes on a greater public interest. As a result, it acts as a very important and effective means of vocational guidance for schoolchildren, especially in the upper grades.
  6. Variety of forms and methods. It is very difficult and perhaps impossible to list all the forms and methods of extracurricular activities. The forms of organizing socially useful activities and increasing the cultural horizons of schoolchildren have become more diverse.
  7. mass character. It covers not only individual lovers of nature, art, but all students. Its mass forms are complemented by group and individual lessons. Sometimes not all students are involved in extracurricular work, but only an asset. The rest, primarily the difficult guys, remain outside the sphere of organized influence. "Involving such children in interesting extracurricular work helps them to re-educate, increase interest in joint activities." (2: pp. 98-99)

Considering the features of the organization of extracurricular activities proposed by Vulfov and Potashnik, we can draw the following conclusions:

  1. Extra-curricular activities should indeed be organized on a voluntary basis and should not be associated with the framework of compulsory programs. Extra-curricular work allows you to take into account the diverse interests of schoolchildren, significantly deepen them and expand them in the right direction.
  2. The composition of the groups of different ages contributes to the conditions for creating patronage work. The older students help and supervise the work of the younger ones. This does not interfere, but often helps - grow faster, grow up, learn to make friends.
  3. The wide use in extracurricular work of various tasks related to conducting experiments develops research abilities in schoolchildren. In addition, the need to describe the observed, draw conclusions, talk about the results develops students' thinking, observation. Makes you think that they didn't notice before.
  4. Extra-curricular work really acquires a great socially useful orientation. In the process of work, students need to make it clear that we have a common house - this is our city, our country, our Earth. And if we do not learn to guard and protect our Home ourselves, then no one will do it for us.

The formation of the modern worldview of children in the process of extracurricular work in the biological cycle of disciplines is a painstaking task and requires the teacher's great pedagogical efforts, skills and abilities. As practice shows, the educational value of extracurricular activities in biology, their effectiveness largely depends on compliance with a number of requirements.

One of the most important requirements for extracurricular work is its close connection with life. The work of the circle should promote familiarization with the surrounding life and active participation in its transformation.

The organization of extracurricular activities allows, firstly, to take into account the diverse interests of schoolchildren and significantly deepen and expand their knowledge in the right direction, using both an individual approach and the work of schoolchildren in "small groups". Secondly, and perhaps most importantly, extracurricular work allows students to work with different rates of learning material, which often contributes to the involvement of students with poor academic performance and little interest in biological science.

The content and organization of extracurricular activities must be subordinated to the educational tasks of the school. It is important to select such material that would contribute to the expansion of general educational horizons, moral and labor education, aesthetic tastes and physical strength. The effectiveness of extracurricular activities is significantly increased if they are carried out systematically, regularly, and not from case to case.

An important requirement for the organization is accessibility, feasibility. Excessive exercises do not give the desired results. They are not interesting for students, do not fascinate them. It is especially necessary to ensure their accessibility in the primary grades. In circle and mass work in these classes, a large place is occupied by a variety of games and entertainment, elements of romance. The main requirement is variety and novelty. It is known that students do not tolerate monotony and boredom. They do not show interest in monotonous classes, do not attend them. In order for schoolchildren to willingly go to the classes of the circle, to the matinee, to the conference, it is necessary that it be exciting, varied, new there. It's no secret that extracurricular activities, which are more relaxed than a lesson, sometimes reveal the innermost secrets of a child's soul more fully. And the variety of forms of extracurricular work, to which schoolchildren can be involved, is the most important means of shaping not only cognitive interest students, but also serves to activate their citizenship in other areas.

In the methodological literature and the practice of school work, the concept of "extracurricular work" is often identified with the concepts of "extracurricular work" and "extracurricular work", although each of them has its own content. In addition, extracurricular work is often considered a form of learning. Based on a comparison of these concepts with other generally accepted methodological concepts, "extracurricular work should be attributed to one of the components of the system of biological education of schoolchildren, extracurricular work - to one of the forms of teaching biology, and extracurricular work in biology - to the system of additional biological education of schoolchildren" (9 : p.254).

An analysis of the biological cycle textbooks shows that they do not fully meet modern requirements. Many textbooks are characterized by a weak connection between the material being studied and practice, an overload of presentation with secondary facts and details without a clear allocation of tasks for managing students' independent work, which ultimately hinders the development of students' cognitive interests. Therefore, becoming scientific knowledge students in the lessons of the biological cycle is impossible without the consistent continuation of this work in extracurricular activities.

An important role in extracurricular work is played by scientific and educational evenings, circle work, extracurricular homework, olympiads, if they are held not on a case-by-case basis, but systematically. The problem is not only the quality of teaching subjects, but the revival of extracurricular work is most relevant today. Playing, answering quiz questions, solving puzzles, rebuses, crossword puzzles, children will not only learn a lot about this wonderful world of nature, but also learn how to draw conclusions, come up with hypotheses, remember the names of plants and animals.

The results of extracurricular tasks are used in the biology lesson and are evaluated by the teacher (he puts marks in the class journal). Extracurricular work includes, for example: observations of seed germination, assigned to students when studying the topic "Seed" (grade 6); completing a task related to observing the development of an insect when studying the type of arthropods (Grade 7). Extracurricular activities also include summer assignments in biology (6th and 7th grades) provided for by the curriculum, as well as all homework assignments of a practical nature.

Extracurricular work of students, in contrast to extracurricular and extracurricular activities, is carried out with out-of-school institutions (stations for young naturalists, institutions of additional education) according to special programs developed by employees of these institutions and approved by the relevant public education authorities.

Educational and educational value of extracurricular work in teaching biology

The changes taking place in society determine new requirements for the national education system. Successful self-realization of the individual during the period of study and after its completion, its socialization in society, active adaptation in the labor market are the most important tasks of the educational process.

In the system of school education, according to the concept, the biological cycle of disciplines occupies a special place, makes a significant contribution to the comprehensive development of the individual, forms a modern natural-science picture of the world in the younger generation. But practice shows that in the biological discipline they reduce the content (time). Therefore, the teaching of biological disciplines gives more and more positive educational results if the educational process is connected with extracurricular activities, the importance of which in the general system of education and upbringing is increasing today. Their role is to expand knowledge, develop skills, foster a responsible attitude towards nature. As the study of the literature on this subject shows, at present the problems of biological and environmental education and upbringing are being studied in various directions:

Issues of environmental education in extracurricular and extracurricular activities students found their development in the works of A. N. Zakhlebny, S. M. Zaikin, V. D. Ivanov, D. L. Teplov and others. classes.

In the studies of teachers O. S. Bogdanova, D. D. Zuev, V. I. Petrova, the methodological and general theoretical foundations of the methodology for organizing extracurricular activities of students were developed different ages, which made it possible to penetrate into the essence of the process of extracurricular work, to determine effective ways of organizing.

The works of A. N. Zakhlebny, I. D. Zverev, I. N. Ponomareva, D. I. Traitak contribute to the improvement and methodological support of environmental education, as well as the ecologization of educational subjects;

Psychological and pedagogical aspects of formation ecological culture teachers and students are revealed in the works of such scientists as S. N. Glazicheva, N. S. Dezhnikova, P. I. Tretyakova and others;

The problems of the theory and practice of introducing students to environmental research work, training teachers for the environmental education of schoolchildren are considered in the works of S. N. Glazichev, I. D. Zverev, E. S. Slastenina and others;

Famous psychologists B. G. Ananyev, L. I. Bozhovich, V. A. Krutetsky and others, taking into account the age characteristics of students, studied the conditions and mechanisms for organizing extracurricular work related to the feelings, will and interests of schoolchildren.

The value of extracurricular work in biology has been proven by both methodologists and experienced biology teachers. It allows students to significantly expand, realize and deepen the knowledge gained in the lessons, turn them into strong beliefs. This is due, first of all, to the fact that in the process of extracurricular work, not constrained by a certain scope of lessons, there are great opportunities on the ecologization of biology, on the basis, as noted, first of all, of environmental education.

Conducting experiments, observations of biological phenomena, schoolchildren acquire, on the basis of direct perceptions, specific ideas about the objects and phenomena of the surrounding world, about environmental issues etc. Conducted by students, for example, long-term observations of the growth and development of a flowering plant or the growth and development of a cabbage butterfly, or an ordinary mosquito, or experiments related to the development of conditioned reflexes in animals of a corner of nature, leave in the mind children have deeper traces than the most detailed stories or conversations about it using visual tables and even special videos.

The wide use in extracurricular work of various tasks related to conducting observations and experiments develops research abilities in schoolchildren. In addition, the specificity of the observed phenomena, the need to briefly write down the observed, draw the appropriate conclusions, and then talk about it in a lesson or circle class, contributes to the development of students' thinking, observation, makes them think about what used to pass their attention. In extracurricular work, individualization of learning is easily carried out and a differentiated approach is implemented.

Thus, it can be concluded that extracurricular work allows taking into account the diverse interests of schoolchildren, significantly deepening and expanding them in the right direction, and preparing them for career guidance activities.

In the process of extracurricular work, performing various experiments and making observations, protecting plants and animals, schoolchildren come into close contact with wildlife, which has a great educational influence on them.

Extracurricular work in biology makes it possible to more fruitfully implement two principles of education - the connection of theory with practice, the connection of biology with life. It involves schoolchildren in various feasible work: preparing the soil for setting up experiments and observing plants, caring for them, planting trees and shrubs, preparing food for feeding birds, caring for farmed animals, which, in turn, instills in them a sense of responsibility for entrusted business, the ability to bring the work started to the end, contributes to the development of a sense of collectivism.

If extracurricular work is associated with the production of visual aids from materials collected in nature, as well as dummies, tables, models, the organization of biological olympiads, exhibitions, the release of wall newspapers, it causes the need for schoolchildren to use popular science and scientific biological literature, to introduce them to extracurricular reading .

The great importance of extracurricular work in biology is due to the fact that it distracts students from an empty pastime. Students who are fond of biology devote their free time to observing interesting objects and phenomena, growing plants, caring for sponsored animals, and reading popular science literature.

Summing up the importance of extracurricular work, we can conclude that well-organized extracurricular work contributes to the development of:

  • interest, creativity and initiative of schoolchildren;
  • observation and independence and decision-making;
  • wider mastery of intellectual and practical skills and abilities;
  • the ability to use the acquired knowledge in matters of nature conservation;
  • awareness in deepening the knowledge about nature gained in the lesson, which allows you to turn them into strong beliefs;
  • understanding the significance and value of nature in human life, which contributes to the formation of a holistic worldview;
  • responsible attitude towards nature.

Thus, extracurricular work in biology has great importance both in solving the educational problems of the school biology course, and in solving many general pedagogical problems facing the general education school as a whole. Therefore, it should occupy a prominent place in the activities of every biology teacher.

Lecture Extracurricular, extracurricular and extracurricular work in biology.

Today we need to deal with these three concepts. How do they differ, what types of work are there. Let's discuss together first.

Extracurricular work is a form of organizing students to perform outside the lesson. obligatory, related to the study of the course practical work on individual and group assignments of the teacher. Extracurricular work is obligatory for all students, it is set, and most importantly, then the teacher checks. The organization of this kind of work is dictated by the need for long-term observations of natural objects. It happens that in order to see the results of the experiments, they need to be laid a few days before the lesson. The teacher gives the task to the students in a timely manner. Examples of such experiences:

Botany

- germination of pea seeds - 2 days

- germination of wheat grains - 4-5 days

- germination of pumpkin seed - 5-6 days

- the formation of starch in the leaf during photosynthesis - 2-3 days

- movement of water with mineral salts along the stem - 3 days

- development of roots in the stem cuttings of tradescantia - 5-7 days

- development of roots on a begonia leaf - 2 months

- cultivation of moss seedling from spores - 15-20 days

- disintegration of lichen thallus into algae and fungus - 7 days

By zoology

- different phases of development (metamorphosis in beetles - mealworm)

- development of the fruit fly Drosophila

- breeding aquarium fish

- behavior of domestic animals (cats, dogs, parrots)

- spider behavior

- development of reflexes in birds (on the example of winter feeding of tits and sparrows)

Such observations can be carried out in a living corner, at home or in nature. Sometimes tasks need to be rescheduled for the spring-summer period, then they must be accompanied by clear instructions. Students should keep their notes in a diary.

Extracurricular work is of great importance:

- develops independence

- instills interest in biological objects and natural phenomena

- students acquire research skills

- Accuracy and diligence develops

The teacher has the opportunity to enrich the biology classroom with various objects, giving students individual tasks for the summer. But summer assignments should not be just the collection of any biological material. Students must have a task and comprehend its implementation. The teacher explains that one should strive for the quality of the collected material, and not for its quantity. It is necessary to prepare well, properly (fix or dry the object).

In the modern curriculum, biology lessons are given only one hour a week, but there are schoolchildren who are fond of biology. And their interests are much broader than program ones. To support such interest, to consolidate and develop it is the task of the teacher. It is difficult to do this within the framework of training sessions, therefore extra-curricular naturalistic and environmental work is carried out, which is voluntary.

extracurricular activities there is a form various organizations voluntary work of students outside the classroom under the guidance of a teacher to excite and manifest their cognitive interests and creative initiative in expanding and supplementing the school curriculum in biology.

What do you think extra-curricular biology classes should be like?

The use of tasks in extracurricular activities related to conducting observations and experiments contributes to the development of research skills. At the same time, it is necessary to orient children to a clear design of the course of observations and their results.

Properly organized extracurricular activities does not overload students. At the same time, it is necessary to warn the teacher against making mistakes in organizing extracurricular activities such as school lessons and other compulsory activities, from turning extracurricular activities into original extra lessons biology. Extra-curricular activities should arouse naturalistic interest among schoolchildren, activate them Creative skills and at the same time contribute to their relaxation. That's why extracurricular work should be varied, versatile and not duplicate academic work at school.

A significant place in extracurricular work is given to labor: making collections, herbarium, crafts from natural material etc., which is of great educational value. She introduces schoolchildren to various feasible work: preparing the soil for setting up experiments and observing plants, caring for them, planting trees and shrubs. preparing food for feeding birds, caring for farmed animals, which, in turn, instills in them a sense of responsibility for the assigned work, the ability to bring the work started to the end, and contributes to the development of a sense of collectivism.

The great importance of extracurricular work in biology is due to the fact that it distracts schoolchildren from an empty pastime. Students who are fond of biology devote their free time to observing interesting objects and phenomena, growing plants, caring for sponsored animals, reading popular science literature.

Extracurricular activities can be classified according to different principles:

ü taking into account the number of participants in extracurricular activities, individual, group and mass (frontal) types of extracurricular activities are distinguished (Table 5);

ü for the implementation of classes in time frames - episodic (evenings, trips, olympiads, conferences) and permanent (circles, electives, societies);

Research work in nature, in a corner of wildlife

It is important to ensure a comprehensive combination various forms in an appropriate sequence.

Individual shape Extracurricular activities take place in all schools. Trying to satisfy the needs of individual students who are interested in biology, the teacher invites them to read this or that popular science book, make observations in nature, make a visual aid, pick up material for the stand. Sometimes, while satisfying the curiosity of individual students, the teacher does not set any goal for himself, does not direct this extracurricular work in a certain direction, and does not even consider that he is conducting it. This pattern is often observed among teachers who do not have sufficient work experience.

Experienced teachers clarify the biological interests of schoolchildren, constantly keep them in their field of vision, set themselves the task of developing their interests in biology, select appropriate individual lessons for this, gradually complicating and expanding their content. Some students create their own home wildlife corners. The teacher gives instructions to such students for setting up experiments at home. Individual extracurricular activities are essentially a voluntary variety of home and extracurricular work.

The most common types of individual extracurricular work include experiments and observations on plants and animals in nature, in an educational experimental site, in a corner of wildlife, making artificial nests and observing their settlement, self-observation, making visual aids, preparing reports, abstracts, and much more. other.

In carrying out individual work, it is very important to take into account the individual characteristics of students in order to deepen and develop their interests in the relevant areas. Extracurricular activities can also encourage choice future profession, have a direct impact on the profile orientation of education at school, on the choice of specialty and on post-secondary education.

Mass episodic classes are organized on the initiative of a biology teacher and are held with the active participation of a circle of young naturalists, school student activists, school administration, and subject teachers. Plans for holding mass events are approved by the pedagogical councils of the school.

Involved in mass work a large number of students- parallel classes, the whole school. It is characterized by a socially useful orientation. Typically, the school conducts such types of mass work as school biology olympiad, (School Biology Olympiads are held annually in several rounds. A week before the appointed time, an announcement is posted about the procedure for its holding, a list of recommended literature and requirements for written work that are submitted to the Olympiad.)

Weeks of Biology, (Biology week at school is a complex event that combines various forms of extracurricular activities: evenings, conferences, contests of assignments, newspapers, essays. Holding a week of biology at school allows you to show how educational and extracurricular work in the subject is set at school. This is a display of achievements in the subject, as well as the promotion of biological knowledge.)

Weeks of health, the holiday "Day of Birds", "Earth Day", campaigns for planting trees and shrubs, collecting seeds and other food for winter feeding of birds; making and hanging bird nests.

Occasional events can also be group. To carry out such work, the teacher selects a group of students who are interested in biology, instructs them to select certain material, issue a thematic wall newspaper, prepare and conduct reports, art numbers for the holiday. Usually, after the completion of any mass event, the work of the episodic group stops. To conduct another mass event, the teacher attracts students from the previous episodic group or creates a new one.

Occasional group extracurricular work is also organized in connection with the desire of the teacher to study the wildlife of his region more deeply, for example, to make an inventory of tree and shrub vegetation, to find out the species composition of birds inhabiting places near water bodies; to study the daily activity of animals of various species, the "biological clock" of plants. The need to organize such episodic group work usually arises when there is no circle of young naturalists at school.

One of the important group forms of extracurricular education is biological circles.

Biological circle is the organizing center for extra-curricular activities.

Principles of organization of youth circles

To accept in the circles everyone who wants to, including those who are poorly performing and not disciplined enough. The latter often begin to be interested in biology and behave much better than in the classroom. Therefore, work in the circle should be considered as a means of education.

The number of students in the circle should not exceed 15 people. If there are more applicants, then 2 groups will be organized.

The work of the circle should be carried out on student self-government. Therefore, it is necessary to elect an asset of the Council for self-government: a headman, 3-4 link assistants to the headman, an editorial board for issuing a newspaper, bulletins, announcements about the start of the work of the circle, etc.

The leaders of the circles should be subject teachers, and in the lower and middle grades there can be junior high school students - grades 10-11.

Drawing up a work plan for the circle, taking into account local history, ecology, environmental protection, and especially nature-enhancing activities.

The number of circle lessons is from 2 to 4 per month.

Summing up the work of the circle after studying the topic, or for a quarter, half a year, a year. The most effective and visual is reporting and summing up in the form of scientific evenings, conferences, role-playing games, exhibitions, competitions, olympiads, writing and defending abstracts, reports, naturalistic campaigns, etc. into socially useful work.

Planning the work of the circle.

When drawing up a plan, one should proceed from the protection, enrichment and study native nature and conducting research activities in the form of experimentation with plants. In this regard, it is advisable to plan the following topics-sections:

Protection of Nature native land:

a) identification of natural objects subject to protection (secular oaks, rare plants, animals, protected parks, etc.);

b) protection of birds, fish, animals (making feeders and feeding birds, animals in winter time- 7-8 out of 10 tits die in winter);

c) work of "green" and "blue" patrols.

Enrichment of the nature of the native land:

a) the resettlement of useful animals in new habitats (but not ants, bedbugs and the Colorado potato beetle!);

b) growing rare plants in their gardens and at the school educational and experimental site (varieties of cabbage, Japanese Daikon radish, etc.);

c) landscaping of the native land (laying gardens, squares, parks, flower beds near the school, in the village).

Studying the nature of the native land:

a) excursions, hiking trips, travels around the native land (all circles at all times of the year, especially during the summer holidays);

b) collecting literary information about the nature of the native land and studying it;

c) creation of school local history museums;

d) research activities in the form of experimentation at the school's educational and experimental site, in individual gardens, garden plots.

The work plan of the circles is drawn up for half a year or a year.

Requirements for the work of youth circles.

In order for the youth work to be pedagogically effective, the teacher must remember the requirements that must be made to it:

a) the work started should always be completed, analyzed and summed up.

b) young naturalists should always and purposefully be interested in this work.

c) leaders of young naturalists' circles should always and in everything be a positive example for young naturalists.

It is very useful to finish many topics of youth activities with socially useful work (Forest and Garden Week, Bird Days). exhibitions, expeditions, hikes, etc. Interesting and valuable results are obtained by correspondence with circles of other regions, regions of the country and the exchange of stepchildren with seeds and cuttings of especially new, valuable, rare, exotic plants for the area.

Biological circles according to the content can be divided into groups:

1. Entertaining. Their main task is to attract students to the study of biology, instilling interest in the subject. They form only a superficial interest in biology, without deepening the study of any issues.

2. Circles, the content of which corresponds to the program of the main course. The task of these circles is to improve the knowledge and skills of students received in the lesson.

3. Mugs. On which students are given practical tasks related to the formation of skills, abilities and knowledge on certain issues (florists, phenologists, aquarists).

4. Circles dedicated to special issues of biology studied in the lessons (ornithologists, entomologists). These circles contribute to an in-depth study of some narrow section of biology.

In recent years, in the development of circle work, there have been trends of strengthening environmental and local history work; the level of their science has risen.

A special type of extracurricular work is electives. Small groups of students 15 - 17 people work according to the programs or according to the author's programs of the teacher. The purpose of extracurricular activities is to give students deeper knowledge on certain topics of biological science, significantly exceeding the volume of the school curriculum.

Extracurricular activities, the second type of group activities, are also built on a voluntary basis. They differ from youth circles in that they should be carried out with small groups (no more than 10-15 people) of students according to special, more complicated, in-depth and expanded programs of the Ministry of Education or according to programs drawn up by the head (teacher or specialist) of the elective.

The purpose of optional training is to give students knowledge and practical skills in various sections of biological, agricultural, methodological, pedagogical science in a volume much greater than school curriculum. It is also of great importance for the professional orientation of students, since only those who are going to work in agriculture or continue their education in special educational institutions(agricultural, pedagogical, biological, medical, etc.). In other words, electives of profiles are most appropriate now: biological, pedagogical, agronomic (field growers, vegetable growers, gardeners, beekeepers, machine operators, farmers, entrepreneurs, managers, livestock breeders), medical, environmental.

Class attendance is required for enrolled students. They are held according to a fixed schedule and the work of the supervisor-teacher of extracurricular activities is paid. It is highly expedient that optional activities are conducted not only and not only by school subject teachers, but also by invited scientists from universities and research institutes, experimental stations, highly professional practitioners, production specialists - agronomists, livestock specialists, engineers, doctors, etc. The results of the work of electives may not be not only the training of field growers, livestock breeders, machine operators, drivers, projectionists, photographers and other specialists, but also the manufacture of equipment for the biology room, living corner, school training and experimental site. In short, the forms of optional and young students' work are diverse, voluminous and significant from the applied and pedagogical points of view, because here there is not only a deepening and expansion of knowledge and the formation of skills, but also labor, moral, aesthetic upbringing, as well as the upbringing of a sense of pride in oneself, one's own school, etc. Extracurricular activities impose increased responsibility on teachers, because here students who are especially interested and gifted are eager to receive new, relevant, original knowledge. It is bad and unacceptable that electives turn into additional extracurricular activities, for example, in solving problems, examples, exercises, preparing for tests, tests, exams. In contrast to the usual subject class-lesson classes, optional ones should be dominated by more active forms of preparation: lectures, seminars, business and role-playing games, independent laboratory and practical work with literature not only educational, but also special additional, writing and defending abstracts and, finally, independent implementation of practical and especially research experimental work. All this in a complex contributes to the development and formation of skills to independently and creatively apply the knowledge gained in the elective course in practice, in life.

You can not force students to attend those subjects that they have not chosen themselves. But some teachers force students to attend their electives. Often such teachers do not give high grades (4 and 5) in a quarter of those students who do not go to their extracurricular classes. The reason is that he does not go to an elective, which means he is not interested in the subject, and therefore does not deserve more than a triple. This is unacceptable, unpedagogical.

A group of "assistants" is created in order to equip and maintain in due order a biological study, a living corner, a school-based educational and experimental site. Undoubtedly, they must do what is within their power and organically connected with the process of teaching biology. In particular, they make teaching aids, instruments, tools, inventory, tables. Prepare handouts, cages for small animals (rabbits, birds, etc.), shelves for indoor plants - Environment Day;

Efficiency of any environmental action depends on the quality of its implementation on the ground using local history material.

All of the above forms and types of extracurricular work in biology are interconnected and complement each other. In the emergence and development of the relationship between them, a certain pedagogical pattern is observed. Interest in working with living organisms usually arises in schoolchildren when performing individual tasks. Having successfully completed certain tasks of the teacher, they usually ask for additional extracurricular work. If there are several such students in the class, the teacher unites them into temporary naturalistic groups, and later into circles of young naturalists, working in which they take an active part in the preparation and conduct of mass naturalistic events.

The use in the lessons of the results of individual, episodic group and circle work (for example, demonstrations of manufactured manuals, reports on observations made, reports prepared on the basis of extracurricular reading) contribute to the involvement in extracurricular work of students who have not previously shown due interest in it. Often, some schoolchildren who at first took a passive part in mass extracurricular work on landscaping the school territory, making bird houses, as listeners, later become either young naturalists or are actively involved in individual or group episodic work carried out on the instructions of the teacher.

A study of the experience of schools shows that extracurricular work in biology is carried out in all its forms. Almost every school has a naturalistic circle, various public events are held, individual and group episodic classes are organized. However, extracurricular work often comes down to organizing exhibitions of students' summer work, holding olympiads, Biology Week, and Bird Day. The rest of the time, houseplants are usually cared for, bulletins are issued based on the use of materials from popular science periodicals, and “Entertaining Biology Hours” are held. Meanwhile, the specificity of extracurricular work in biology, the science that studies living things, is associated with such types of work that include independent research of schoolchildren, put them in the position of pioneers, and arouse real interest in the knowledge of nature.

All types of extracurricular activities are outside the scope of academic work in biology. However, they are an integral part of the entire educational process, the most important means of educating and developing students of different classes. The organization of this work at school serves as one of the criteria for the teacher's creative work, an indicator of his pedagogical excellence and professional responsibility.

Everything is created intelligently and conveniently for the life of all living beings. Nature is generous and disinterested, it gives everything for human life - food, water, clothes, fuel, surrounds with beauty.

Slide 4. Video "Ecology"(pollution environment)

Guys, what is this video about?

What are we going to talk about today?

Of course, today we will talk about ecology, the problems of environmental pollution and its protection.

Our class hour today is unusual, we are going with you to the ecological patrol.

Slide 5. We will stop at various stops, solve problems, complete tasks and, of course, earn points. For each point earned, the team receives a globe chip.

Slide 6-15. Stop 1"Ecological Miracle Tree"

Here we will test your knowledge of ecology. The guys take turns approaching the miracle tree, tearing off the leaflet on which the question is written. Discuss in the team for 1 minute and give an answer, if it is difficult to answer, to this question another team can answer. For every right question 1 point

Questions:

  1. What plants are bioindicators that reveal the general pollution of the environment?(lichens).
  2. What does the term "ecology" mean?("ekos" - house, "logos" - doctrine).
  3. What components pollute the atmosphere?dust, gases, smoke, microorganisms, noise, radiation).

  2. Are earthworms good?(yes, they are food for animals and birds, they are involved in improving the structure of the soil - they loosen the soil, form humus, disinfect the soil).
  3. What role do predatory beasts and birds?(they are orderlies).

Slide 16. Stop "Environmental situation"

Guys, at this station, each team receives a card with an environmental situation.(Attachment 1). Discuss the task and give an answer.

Slide 17. Stop "Biosphere"Guys, on your tables is the text of the story with environmental errors(appendix 2) . Find them and suggest rules of behavior in nature. 1 point for each correct error found.

Guys, tell me, why is this stop so named? Indeed, the biosphere is a shell in which all components of animate and inanimate nature interact: water, soil, air, animals, plants and humans.

Slide 18-20. Stop "Red Book"

Student :

Protected by the Red Book

How many rare animals and birds

To survive the many-sided space

For the light of the coming lightning.

So that the souls do not become empty,

Animals are protected

The snakes are guarded

Even the flowers are protected.

Guys, at this stop you are invited to guess the animals and plants that are listed in the Red Book of the Fltai region. Name them (on the tables at the teams there are photos with animals and plants). For each animal or plant you guessed correctly, you get 1 point, if you correctly name this animal, you get one more point.

  1. Guys, what is the role of the red book?

Student.

I love my region. How strange to hear

After all, every person loves his land!

But the sky is blue here, the sun is higher!

And May is painted in the color of lilac here.

Summer smells like rain and hay

The river calls with coolness ...

And autumn is dressed in gold,

Clouds are floating,

Winter beckons into the distance,

On a frosty morning, the snow crunches,

And the river will come out of its banks in April.

And the forest rustles in spring,

I love my region! I have seen many places

And you can even go around half the world,

But closer and dearer to the native land,

I don't think I can find it anymore.

Student.

Once having gathered with the last forces,

The Lord created a beautiful planet

Gave her the shape of a big ball

And planted trees and flowers there

Herbs of unprecedented beauty

Many animals are found there

Snakes, elephants, turtles and birds

Here's a gift for you, people, own

Plow the land, sow bread

I bequeath to you all from now on

You protect this shrine.

Tree, grass, flower and bird

They don't always know how to defend themselves.

If they are destroyed

We will be alone on the planet.

Student.

What happened? What is forgotten? What's broken?

I understand more and more clearly: there will be trouble!

There is no more nature left on earth,

And we live in the environment.

Student.

I feel the pain of loss more and more

It's bad with flora and fauna discord.

And in salads they say only nitrates,

And nitrates in every fish sit.

Student.

Everything is more alarming on the planet from year to year!

And even a mosquito understands:

Or will we protect our nature,

Or we'll fly into the ozone hole!

Student.

People, people, what have you done to the planet?

You yourself have lost your way

After all, there is no other like it in the world,

Yes, and there are no spare parts in nature!

Student.

I don't want this kind of world

Where everything is so gray and dull ...

Student.

What have we done to nature?

How can we look into her eyes now?

In dark poisoned waters

Heaven that smelled of death.

Student.

My planet is a human home

But how can she live under a smoky hood

Where is the gutter ocean?

Where all nature is trapped

Where there is no place, neither stork nor lion,

Where the herbs groan: "I can't take it anymore."

Student.

I look at the globe, the globe of the earth,

And suddenly he sighed as if alive!

And the continents whisper to us:

You take care of us, take care!

In the anxiety of groves and forests,

Dew on the grass like a tear.

And the springs quietly ask

You take care of us, take care!

The deep river is sad

Their own, losing their shores,

You take care of us, take care!

The deer stopped his run:

"Be a human being!

We believe in you, don't lie

You take care of us, take care!

I look at the globe

So beautiful and dear

And lips whisper: "I won't lie,

I'll save you, save you!"

  1. Summing up (reflection 2 minutes)
  1. What new did you learn today?
  2. What do you remember the most today?
  3. Do you consider yourself environmentally friendly people?

slide 27. Guys, I would like to end today's event with the following statement:“I picked a flower and it withered. I caught a moth and it died in my palm. And then I realized that you can touch nature only with your heart.”(E.L. Prasolova)

Thank you! All the best to you!

Attachment 1.

Situation #1

On one distant island, people decided to destroy mosquitoes. Used for this pesticides. The mosquitoes really disappeared, but after a while a lot of rats appeared. They attacked the fields and barns in hordes. local residents by eating grain. People could not understand why this "scourge" appeared.

Exercise . Expand the cause-and-effect relationships that led to the development of this environmental situation, describe the consequences and suggest ways out of this environmental situation.

(The pesticides that kill mosquitoes got on the plants, which, in turn, fed on cockroaches (insects). The insects fed on the plants, but did not die from the poison. At the same time, it accumulated in their bodies.

These cockroaches were caught by lizards. They weakened from the poison and became easy prey for cats. For cats, the poison was fatal. Soon they were completely gone from the island. It's time for rats.)

Situation 2.

Maritime transport is extremely polluting the oceans. Tin cans, plastic bottles, paper and plastic bags and other trash. Fishermen leave synthetic fishing nets in the sea.

Exercise. Analyze the consequences of pollution of the World Ocean by sea transport, suggest a way out of this environmental situation.

Answer . This leads to pollution of the ocean, turning it into a landfill. Marine animals are dying, in particular leatherback turtles and seals. They mistake plastic bags for jellyfish and swallow them. The stomach clogs up and the animals die. Very often, tin cans, lumps of fuel oil, and other objects are found in the stomachs of sharks at autopsy, since sharks grab everything in a row when they are hungry.

Often, marine animals (seals, whales, dolphins, birds) cannot live and eat normally, because the mesh tightly tightens their body, it does not decompose in nature and therefore causes torment to animals throughout their lives.

Measures: do not throw into the ocean garbage that is not recycled in nature, conduct explanatory work with sailors and passengers of maritime transport, introduce quotas for fishing.

Situation 3.

The uncontrolled use of mineral fertilizers (nitrogen and phosphorus) leads to a supersaturation of water with organic compounds. This causes the growth of blue-green algae.

Exercise . Briefly describe the further development of the environmental situation and suggest ways to solve it.

Answer.

The rapid development of blue-green algae (“blooming of reservoirs”) is accompanied by intensive consumption of oxygen dissolved in water, the lack of which subsequently causes their death. Dying off and settling to the bottom, algae decompose, which also consumes oxygen. All this entails the mass death of representatives of flora and fauna. Algae secrete a large number of substances that inhibit zooplankton and microflora, and in some cases poison fish, poultry, livestock and humans.

It is necessary to ration the application of mineral fertilizers to the fields, to monitor compliance with the rules for storing mineral fertilizers in warehouses and farms. In case of pollution of water bodies with fertilizers, do not allow livestock to the water body. Fight for the restoration of water resources, carry out wastewater treatment activities, as they also stimulate the reproduction of blue-green algae

Annex 2.

Story with errors

"Sunday in the Forest"

For a week there was only talk in the class about a future trip to the forest. At the last moment, the teacher fell ill. But we decided to go to the forest ourselves. We already knew the way, stocked up on food, took a compass, did not forget the transistor.

With cheerful music we announced the forest - we have arrived! The days were hot and dry, but there was no heat in the forest. The familiar road led us to a birch grove. On the way, we often came across various mushrooms - ceps, boletus, russula. Here is the harvest! Who cut off the elastic legs of mushrooms, who twisted them, and who pulled them out. All the mushrooms that we did not know, we knocked down with sticks.

Halt. They quickly broke branches and lit a fire. We brewed tea in a pot, had a bite and went on. Before leaving the grove, Petya threw out plastic bags and cans. He said: "Microbes will destroy them anyway." The burning embers of the fire winked at us goodbye. In the bushes we found a bird's nest. After holding the warm bluish eggs, they put them back. The sun rose higher and higher above the horizon. It was getting hotter. At the edge of the forest we found a hedgehog. Deciding that his mother had abandoned him, they took him with him - he would come in handy at school. We're pretty tired already. There are quite a lot of anthills in the forest. Petya decided to show us how formic acid is mined. He planed sticks and began to sink them deep into the anthill.

Clouds gradually began to roll in, it became darker, lightning flashed, thunder rumbled. Went pretty heavy rain. But we were no longer afraid - we managed to run to a lonely standing tree and hid under it.

Animated, we walked to the station, jumping over puddles. And suddenly a snake crawled across the road. “It's a viper,” Petya shouted and hit her with a stick. We approached the snake and saw two yellow spots on the back of its head. "It's not a viper," Masha said quietly, "it's already." "It's all the same - a reptile!" - Petya answered.

With armfuls of meadow and forest flowers, we approached the station. An hour later, the train was already approaching the outskirts of the city. It's been a fun day!

Rules:

  • do not turn on loud music;
  • do not pull out mushrooms, and also do not knock down even inedible ones; because

the mycelium is destroyed, the medicine for animals disappears,

the community of insects - fungi - trees is disturbed;

  • for a fire to collect dried wood, and not to break branches. In warm, dry weather, it is forbidden to make fires in the forest;
  • do not leave polyethylene, as it is poorly destroyed

microorganisms (completely destroyed after 220 years) and

metal cans (destroy after 100 years);

  • the fire after burning out should be thrown with earth or poured

water until complete cessation of combustion;

  • do not touch the eggs of birds - the bird may leave the nest;
  • do not take animals and chicks from the forest to the city - if they do not die in the city, they will die when you want to return them to the forest again;
  • do not stick sticks into the anthill - relationships are broken

in this complex community;

  • do not hide during a thunderstorm under a lonely tree - it can

get hit by lightning!

  • in no way destroy snakes, even vipers;
  • meadow and forest flowers should not be torn - the life of the plucked

flowers are short-lived.

Extracurricular lesson in biology

for students in grades 7-8

"Health is great!"


Biology teacher

Korotina Svetlana Nikolaevna


Stary Oskol

2013-2014 academic year

Target: formation of a value attitude of students to their health. Tasks:- expand students' understanding of a healthy lifestyle; to promote the formation of a positive attitude towards health as the greatest value; - modeling of life prospects from the standpoint of a value attitude to health.

Lesson progress

    Conversation “What is health? »
The theme of our class hour "Health is great." Since ancient times, when people met, they wished each other health: “Hello”, “Good health!”. And this is no coincidence. After all, even in Ancient Russia they said: “Health is more expensive than wealth”, “Health cannot be bought”, “God gave health, but we will find happiness”. Indeed, everyone needs health. And what meaning do you put in the concept of "health"? ( Student judgments). Thank you for the interesting definitions, it is felt that the problem of health is in the field of your attention. Every adult will tell you that health is the greatest value, but for some reason, modern youth lists money, career, love, fame among the main values, and puts health in 7-8 place. It has long been established that health should be monitored from childhood. Let's do a little test about your health, you are offered a list of statements, each of which requires a yes or no answer. This information will be useful, first of all, to you.

Test "Your health".

1. I often have a poor appetite. 2. After a few hours of work, my head starts to hurt. 3. I often look tired and depressed, sometimes irritated and sullen. 4. From time to time I have serious illnesses when I have to stay at home for several days. 5. I hardly go in for sports. 6. Lately I have put on some weight. 7. I often feel dizzy. 8. I currently smoke. 9. As a child, I suffered several serious illnesses. 10. I have poor sleep and discomfort in the morning after waking up. For each “yes” answer, give yourself 1 point and calculate the amount.Results.1-2 points. Despite some signs of deteriorating health, you are in good shape. In no case do not give up efforts to preserve your well-being. 3-6 points. Your attitude to your health can hardly be called normal, it is already felt that you upset him quite thoroughly. 7-10 points. How did you manage to get yourself to this point? It's amazing that you're still able to walk and work. You need to change your habits immediately, otherwise... Charting« Healthy lifestyle" Now let's think about our lifestyle and draw up a "Healthy lifestyle" chart. In order to live life wisely, You need to know a lot. Remember the two main rules to begin with: You'd better starve than eat anything, And it's better to be alone than with anyone.
- What makes up a healthy lifestyle? (Students give their opinion) 1. Healthy eating; 2. Daily routine; 3. Vigorous activity and outdoor activities; 4. Absence bad habits. So, what is a healthy diet and what is it eaten with? (Student presentations ). The word is given to the creative group of students "Healthy food". 1. Proper nutrition is the basis healthy lifestyle . At healthy eating the incidence decreases, the psychological state improves, the mood rises, and most importantly, the working capacity and interest in educational activities increase.After a big break, there are empty lemonade bottles in the bin, let's talk a little about what are we drinking? Soda contains acid, which erodes tooth enamel and promotes cavities. For example, apple juice contains many times more acid. The only difference is that there it is natural, although it corrodes tooth enamel, but does not wash out calcium, as it does orthophosphoric acid(E338). It is most often used in sodas. Sodas also contain carbon dioxide , which excites gastric secretion, increases acidity and promotes flatulence. Well, of course caffeine.
