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 lab work, students will conduct a series of experiments to study the common properties of nitric acid compared to other acids, such as acetic acid and lemon juice. Long-term Plan Section Subsections of the Standard Educational Program (SEP) Learning objectives Elements of Groups 17(VII), 16 (VI), 15 (V), 14(VI), and their compounds Nitric Acid.Lab Experiment № 13:“Properties of Nitric Acid Common with Other Acids” 9.1.4.7 to know the molecular formula of nitric acid and explain the formation of chemical bonds between atoms.9.2.1.19 to investigate the properties of nitric acid common with other acids.

In this paper, students will use simple experiments to study the basic chemical properties of hydrochloric acid.

Description: In the course of this work, students will explore some of the properties of acetic acid.

Description: This experiment aims to demonstrate the presence of carbon in common food products. By subjecting sugar and pasta to heat, students will observe the changes in their physical properties.

Description: In this experiment, students will explore the effect of acetic acid on eggshells, which are a rich source of calcium, and draw conclusions about the role of this macronutrient for the body. 

Description: As part of this work, students will gain knowledge about the structure of nitrogen and ammonia molecules by creating 3D models of these molecules with their own hands, as well as using virtual simulation.

Description: As part of this study, students will conduct an experiment aimed at studying the process of protein denaturation.
