Description: In this lesson, students model amino acid molecules using plasticine and toothpicks. They learn to assemble the general formula of amino acids, identify the presence of an asymmetric carbon atom, and distinguish amino acids based on their radical (R). The activity provides a visual understanding of amino acid structures and helps consolidate knowledge of amino acids.
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.
