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
Description: In this lab work, students investigate the chemical properties of acetic acid – one of the most well-known carboxylic acids.

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.
Students will conduct two experiments to study the chemical properties of calcium oxide. In the first experiment, they will observe the reaction of calcium oxide with water, and in the second, with acetic acid.

Description: In this laboratory work, the reaction of diluted acids with metals is studied using the example of the interaction between hydrochloric acid and zinc. During the experiment, hydrogen is released, which can be identified using a qualitative test — a characteristic pop when a lit match is brought near. This study demonstrates the basic principles of chemical reactions between metals and acids, as well as the properties of hydrogen as a gas.
