USING INTERDISCIPLINARY CONNECTIONS IN TEACHING ELEMENTARY CHEMISTRY

Аннотация

The article uses interdisciplinary communication in teaching elementary chemistry in the course "Chemistry" in secondary schools. Materials on pedagogical research and their results. KEYWORDS:- Integration, interdisciplinary communication, teaching chemistry, integrative course content, biogenic elements, macrobiogenic, microbiogenic and ultramicrobiogenic elements, scientific and pedagogical research, the system of continuing education, pedagogical experiments. I Main part. When conducting pedagogical NTRODUCTION research on the teaching of elementary Implementation of the tasks set by the Decree of chemistry on the basis of interdisciplinary the President of the Republic of Uzbekistan dated relevance, first of all, it is necessary to rework August 12, 2020 No.4805 "On measures to the content of educational materials on an improve the quality of continuing education and integrative basis. In the school chemistry course, scientific efficiency in chemistry and biology" special attention is paid to the role of elements in and other regulatory legal acts on chemistry and the periodic table, their atomic structure, biology. the organization of modern education is distribution in nature, physical and chemical relevant. One of the urgent tasks today is to properties and their biological significance. ensure the implementation of such important We know that the material world, including educational decisions, the integration of living organisms, is made up of chemicals, disciplines into chemical education, pedagogical chemicals are made up of molecules, and research of the interdependence of disciplines molecules are made up of chemical elements. To and their further development. The role and date, more than 118 chemical elements have importance of the formation of a holistic been identified, 92 of which are found in nature. worldview in students, ensuring the interaction More than half are part of biological systems. 18 of chemistry and biological sciences in the elements perform biologically important formation of their natural science worldview are functions in the body. 6 of them (H, C, O, P, S, N) incomparable.

The remaining 12 compounds and should be considered as a elements (Na, K, Ca, Mg, Mn, Fe, Co, Cu, Zn, Mo, Cl, scientific and methodological problem, keeping J ) participate in the life of the body. The 10 this issue in the center of attention in teaching metals they contain are called biometals. These chemistry. We recommend that science teachers elements differ from each other in their atomic use the following teaching materials to teach the structure, chemical properties and quantity in biological significance and physiological effects the body. of fluoride from halogens: fluoride is 0.01% by weight of tooth enamel (a compound chemically Living organisms contain a large number of close to apatite). The body receives the necessary elements (oxygen, carbon, hydrogen, nitrogen, fluoride from water (the rate of fluoride in water calcium, magnesium, sodium, phosphorus, sulfur, is 1 mg / l). If a person lacks or has too much chlorine), which are common in nature. fluoride in the body, the tooth will begin to decay The classification of nutrients is based on the and damage the bones. following characteristics: By electronic structure: A decrease in the level of fluoride in the water  Biogenic s-elements: Li, Na, K, Mg, Ca, etc.; leads to tooth decay (tooth decay). Fluorine is found in the body in combination with activators  Biogenic p-elements: O, C, S, Si, P, etc.; of calcium, magnesium and other enzyme  Biogenic d-elements: Mn, Fe, Zn, Co, Cu, Ni systems. When a large amount of fluoride enters Sr, Mo and others. By the amount of these the body, they replace iodine and disrupt the elements in the body: thyroid gland.  Macrobiogenic elements - elements with a As for chlorine, it is believed that 1 • 10–2% of total content of 0.01% or more in the body. chlorine is present in the human body, is present These include O, C, H, N, S, P, Ca, Na, K, Mg in the extracellular fluid of the cell and and others; participates in the formation of hydrochloric  Microbial elements - elements, the total acid. 0.4-0.5% gastric juice, accelerates protein amount of which in the body is 10 ~ 3-10 ~ hydrolysis, increases the activity of protolytic 5%. These include Mn, Co, Cu, Mo, Zn, F, J enzymes, has bactericidal properties. The human and others; body contains about 0.25% chloride ion. These ions affect the electrical conductivity of cell  Ultramicrobiogenic elements - elements membranes, participate in the formation of the with a total content of less than 10 ~ 5% in blood buffer system and
