The authors developed and proposed for use a complex of virtual laboratory work on biology for 9th grade students. The article describes in detail the algorithm for creating virtual laboratory work based on Microsoft PowerPoint 2010. The proposed laboratory work is based on the following topics: "The effect of growth substances on plants using the example of auxin"; "The study of mitosis in the cells of the root of onion"; "Determination of plant and animal species (local region) using the determinant"; "Study of the process of emulsification of fats under the action of bile." The content of the tasks and their wording correspond to the updated educational program of the school of Kazakhstan Republic. The developed complex will help test 9th grade students’ knowledge and skills, identify gaps in their knowledge, plan further training and development, and, if necessary, correct knowledge and skills. The algorithm developed by the authors will allow schoolteachers to use this program to develop laboratory work in the main biologyschool course, as well as for elective classes.
