In the context of improving the modern educational process, the role of organizations for additional education of children is increasing. They are designed to ensure the satisfaction of individual abilities and needs in various aspects of personal development. This fully applies to the activities of the children’s technology park, which operates within the structure of additional education organizations, associated with the introduction of new technologies into the educational process, which presupposes the mastery of experimental skills. Many of the students show interest in studying plants using laboratory equipment. To do this, there is a need to determine the composition of experimental skills, without which it is not possible to purposefully study plants in general, the plant organism, its components and the characteristics of their functioning, in particular. The article concretizes the concept of experimental skill, in the context of which the corresponding groups of skills are defined – organizational, communicative, theoretical and practical, indicating specific skills in relation to each of them with brief explanations. Purpose of the article. Updating the importance of using the potential of the children’s technology park in students performing research work on the study of living systems - the plant organism in the BIOquantum laboratory based on the use of an identified and characterized set of experimental skills. Research methodology. The methodological basis of the work performed is the activity approach, which serves as the basis for identifying the composition and characteristics of experimental skills, without which it is not possible for students in the field of additional education to purposefully carry out experiments in the BIOquantum laboratory of the children’s technology park. Research methods. The following methods were used: study and analysis of published sources on the topic of the article, a deductive basis for expressing the obtained materials and generalization in drawings. Conclusion. The identified and characterized experimental skills – organizational, communicative, theoretical and practical – act as a means of implementing the research activities of students in the field of additional education to carry out experiments on studying the plant organism in the BIOquantum laboratory of the children’s technology park.
