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.

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 activity, students will investigate the composition of photosynthetic pigments in the leaves of various plants using the method of paper chromatography. Rf values for each pigment will also be calculated, allowing to establish the link between chloroplast structure and its function.
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 work, students investigate the chemical properties and reactions of various carbohydrates: glucose, starch, and sucrose. Qualitative reactions will be performed to identify their reducing properties and their ability to undergo hydrolysis. Long-Term Plan Section Standard Curriculum Subsections: Learning Objectives: Chemistry of Living Systems Structure, Properties, and Uses of Carbohydrates 11.5.1.11 – perform a qualitative test for starch11.5.1.12 – name the hydrolysis products of sucrose, starch, and cellulose11.5.1.13 – compare the structure and properties of starch and cellulose
