During this laboratory work, students perform experiments demonstrating the characteristic properties of calcium and magnesium compounds. These experiments help identify the similarities in the chemical properties of Group IIA elements.
In this laboratory work, students investigate the properties of halogens and their compounds by observing characteristic chemical reactions of halide ions. These reactions are accompanied by color changes and precipitate formation, allowing students to visually confirm the presence of specific ions in solution.
Description: In this laboratory work, students study modificational variability using the growth of mung bean seedlings under different conditions as an example. During the experiment, the length of the stems is measured, and a variation series and distribution curve are constructed. This helps identify the patterns of modificational variability and consolidate knowledge about its manifestations in living organisms. Long-term plan section Subsections of the Standard Curriculum Learning objectives Patterns of heredity and variability Modificational variability. Variation series of traits. 10.2.4.1 to study the patterns of modificational variability
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.

Description: In this experiment, the composition of vegetable oils is studied using a qualitative reaction to detect the presence of unsaturated bonds. This is done by observing the interaction of oils with iodine solution and comparing their behavior with other organic compounds.
Laboratory work #5: «Qualitative Reactions for Unsaturation» Read More »
Description: During this work, students observe the combustion of ethanol, perform qualitative tests for monoatomic alcohols and for polyatomic alcohols. These experiments help explore the physical and chemical properties of alcohols with different structures. Ұзақмерзімді жоспар бөлімі Үлгілік оқу бағдарламасының (МЖМБС) бөлімшелері Оқу мақсаттары Alcohols: monoatomic and polyatomic. Classification and chemical properties. 10.4.2.19 – classify alcohols by the position of the functional group and the number of hydroxyl groups;10.4.2.20 – carry out qualitative reactions for monoatomic and polyatomic alcohols.
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
Description: In this lab work, students investigate the effect of external factors — temperature and pH — on protein structure. Egg white is used as an example, as it contains the protein albumin, which is sensitive to changes in the environment. During the experiment, students observe the process of protein denaturation under the influence of acid, base, and heat.
Description: In this lab, students will conduct the well-known “Elephant Toothpaste” experiment, which serves as a vivid demonstration of a catalytic reaction.
Description: In this lab work, students build models of molecules with covalent bonds: nitrogen (N₂), oxygen (O₂), and diamond (C). The activity includes hands-on modeling using clay and toothpicks, as well as constructing 3D models using the MolView online platform. Students explore types of covalent bonding, hybridization, and the relationship between molecular structure and properties.
