EXPLANATORY NOTE
In the system of natural science education, chemistry as a subject occupies an important place in understanding the laws of nature, in the material life of society, in solving global human problems, in forming a scientific worldview, as well as in fostering ecological culture among people.
Goal of the subject implementation:
To equip students with the basics of chemical knowledge necessary for everyday life, to lay the foundation for further improvement of chemical knowledge in senior classes, and to properly guide students' behavior in the environment.
Objectives of studying chemistry:
To form students' knowledge of the basics of chemical science: the most important factors, concepts, chemical laws and theories, the language of science, and accessible worldview generalizations.
To develop skills to observe and explain chemical phenomena occurring in nature, laboratory, and everyday life.
To form special skills: handling substances, performing simple experiments while following safety rules; correctly applying chemical knowledge in interaction with nature and everyday life.
To reveal the humanistic direction of chemistry, its increasing role in solving major problems facing humanity, and its contribution to the scientific culture of the world.
To develop students' personality: their intellectual and moral improvement, formation of humanistic attitudes, and ecologically appropriate behavior at home and during work activities.

The role of the subject in forming basic knowledge, skills, and key competencies:

1. In the Introduction section, practical work "Familiarization with laboratory equipment. Safety rules when working in a chemistry laboratory" is conducted.

2. The number of hours for Topic 1. Initial chemical concepts. (reduced by 2 hours) by compressing the studied material. The study of concepts: valence (moved from Topic 2. Oxygen. Hydrogen. Water. Solutions.), mole, molar mass, mass fraction of an element in a substance was introduced, as they are necessary for performing calculations and composing chemical formulas. Additional hours (4 h) were included to develop skills in solving calculation problems and chemical problems on chemical reaction equations. Special attention was paid to composing reaction equations and observing the law of conservation of mass – 3 h.

3. Topic 2. Oxygen. Hydrogen. Water. Solutions. Practical work "Production of hydrogen, determination of its purity" was included to develop students' skills in conducting chemical experiments on obtaining and collecting gases, as well as determining differences in gases by physical and chemical properties. The concepts of "allotropy" and "allotropic modification" were included, as they are important for forming a scientific worldview in students.

4. Topic 3. Main classes of inorganic compounds. The number of hours was reduced (by 1 h) by compressing the studied material.

5. Topic 4. Periodic Law of D.I. Mendeleev. The study of the concept "coordination number" was replaced by "oxidation state." The concepts of "oxidizing agent" and "reducing agent," "electron balance" were introduced. 3 hours were added for studying the basics of oxidation-reduction.

6. At the end of the year, 5 hours are reserve hours.

Interdisciplinary connections:
Mathematics (in problem-solving)
Physics (when studying the structure of molecules and atoms, as well as Topic 4 Periodic Law of D.I. Mendeleev, physical properties of substances and their compounds, etc.)
Biology (the importance of chemical elements and their compounds in the life and activity of living organisms, the impact of chemicals on the formation and health of the organism)
Ecology (formation of humanistic attitudes and ecologically appropriate behavior at home and in work activities)
Geography (occurrence of chemical elements and their compounds in nature, ways of most rational application)
Technology (use in food, safety rules) etc.

Requirements for students’ level of training.
As a result of studying chemistry in grade 8, the student must know/understand:
Chemical symbols: symbols of chemical elements, formulas of chemical substances and chemical reaction equations;

Be able to:
Name chemical elements, compounds of studied classes;
Explain the physical meaning of the atomic (ordinal) number of a chemical element, group and period numbers to which the element belongs in the periodic system of D.I. Mendeleev; patterns of property changes of elements within small periods and main subgroups;
Characterize chemical elements (from hydrogen to calcium) based on their position in D.I. Mendeleev’s periodic system and atomic structure features; chemical properties of main classes of inorganic substances;
Determine: composition of substances by their formulas, belonging of substances to a certain class of compounds, types of chemical reactions, valence and oxidation state, type of chemical bond in compounds;
Compose: formulas of inorganic compounds; atomic structure schemes of the first 20 elements of D.I. Mendeleev’s periodic table; chemical reaction equations;
Handle: chemical glassware and laboratory equipment;
Identify: experimentally oxygen, hydrogen, acid and alkali solutions;
Calculate: mass fraction of a chemical element in a substance, mass fraction of substance in a solution, amount of substance, volume or mass based on the amount of substance, volume or mass of reagents or products of a reaction;
Use acquired knowledge and skills in practical activities and everyday life to:
Safe handling of substances and materials;
Ecologically competent behavior in the environment;
Assess the impact of chemical pollution on the human body;
Critically evaluate information about substances used in everyday life;
Prepare solutions of specified concentration.

Forms of knowledge, skills, and abilities control:

• Conversation (at each lesson to develop students’ ability to correctly speak using chemical terms and concepts) + individual questioning;

• Independent work;

• Tests (at the end of each topic);

• Preparation of creative works and presentations on topics:
  Plasma. Fire extinguishing. Fire extinguisher.
  Air - a mixture of gases.
  Life and work of D.I. Mendeleev. Prediction of properties of not yet discovered elements.
  Scientists who studied atomic structure and elementary particles.
  Crystals. Methods of growing crystals at home. And others.

• Conducting and presenting home practical works on topics:
  Physical and chemical phenomena in human life activities. Signs.
  Separation of homogeneous and heterogeneous mixtures.
  Solubility of substances in water and its dependence on temperature.
  Crystallization upon cooling saturated solutions.
  Metals and non-metals in everyday life. Methods of their identification. And others.

• Solving home tasks according to the sample composed in class.
