Description: This experiment offers students hands-on experience in exploring the world of antibacterials, antiseptics and disinfectants  by testing their effectiveness against different microbes.

Description: This laboratory work offers students the opportunity to master the technique of growing bacteria cultures and observe their growth firsthand. While undertaking this cultivation process, they will learn about these ubiquitous single-celled organisms, present in almost all environments from air to soil. These tiny organisms play a crucial role in nature’s cycles, ensuring the constant flow of matter and energy.

Description: In this laboratory session, students will explore the production of fermented milk products. They will discover the essential role bacteria play in this process, breaking down lactose in milk and turning it into fermented milk products with a characteristic taste and aroma. To deepen their understanding, students will craft their own yogurt and cheese, gaining valuable hands-on experience.

Tree rings serve as a valuable source of information about the life of trees, providing insights into their history, forest dynamics, and environmental conditions. This hands-on activity allows students to explore and reinforce their understanding of tree ring structure through the creation of a cardboard puzzle.

Kitchen scraps can be a source for new plants. This experiment is aimed at exploring the possibility of using vegetable residues for plant propagation and their further cultivation.

In this laboratory you will learn how to compare the water tension of water with ethanol. Long term plan section Subsections of the standard curriculum Learning Objectives Cell biology Water and organic matter Properties of water: surface tension, water movement, solubility, boiling and melting points, heat capacity. The biological significance of water and its role as a solvent, in maintaining and regulating temperature. 7.4.1.1 describe the properties and importance of water for living organisms; 7.4.1.2 describe the role of micro- and macroelements in the life of organisms

This work is based on the study of human body reflexes. During the work, students will jointly conduct a series of experiments on several reflexes and analyze the results.

This practical work will help students to expand their knowledge about the mechanisms of water release in plants and their adaptation to the environment.

Information about work In this work, students will be able to see a cross section of a plant stem under a microscope. Students will learn how to independently conduct experiments on seed germination. They will be able to study and observe the formation of plant’s root system.

Information about work In this work, through experiment, students explore the effects of light intensity, temperature, carbon dioxide levels, and water availability on the rate of photosynthesis, providing valuable insights into the intricate relationship between plants and their environment.
