 Laboratory work #4: «Modeling Molecules of Organic Compounds»

Description: In this activity, students build models of simple aliphatic compounds (methane, ethane, propane, 1-chloropropane) using plasticine and toothpicks. Modeling helps visualize the structure of organic compounds, understand the principle of carbon tetravalency, and see the spatial arrangement of atoms in molecules. Section of the Long-Term Plan Subsections of the Standard Curriculum Learning objectives Introduction to organic chemistry Homologous series.IUPAC nomenclature of aliphatic compounds. 10.4.2.3 explain the formation of homologous series and the similarity of properties of their homologues; 10.4.2.4 draw structural formulas of compounds and name them according to IUPAC nomenclature.

Laboratory work #7: «Polymers and Their Properties»

Description: In this laboratory work, students investigate the properties of various types of plastics commonly found in everyday life. The experiment includes observing their behavior during heating and burning, determining their density using water and salt solution tests, and checking their solubility in an organic solvent (acetone). The work allows students to see in practice how the structure of a polymer influences its properties and applications. Section of the Long-Term Plan Subsections of the Standard Curriculum Learning objectives Synthetic polymers High-molecular compounds Polymerization reactions 11.4.2.10 distinguish between the concepts of “monomer,” “repeating unit,” “oligomer,” “polymer,” “degree of polymerization.”11.4.2.11 compose equations of polymerization reactions and study the properties of polymers.

 Laboratory work #3: «Investigating the Shift of Dynamic Equilibrium under the Influence of Various Factors»

Description: In this lab activity, students observe how the formation and dissolution of iron(III) hydroxide precipitate depends on the acidity (pH) of the medium. By adding baking soda and acetic acid, students model the shift in chemical equilibrium in accordance with Le Chatelier’s principle. Long-term Plan Section Standard Curriculum Subsections Learning Objectives: Chemical equilibrium Influence of various factors on equilibriumLe Chatelier-Braun Principle 10.3.3.1 – Predict the effect of changes in temperature, concentration, and pressure on chemical equilibrium 10.3.3.2 – Experimentally investigate the influence of various factors on equilibrium shifts
