This article examines the theoretical and practical foundations of developing a value-based attitude toward nature in preschool children through environmental knowledge. The study emphasizes the importance of environmental education in fostering children's ecological awareness, environmental culture, and responsible behavior toward the natural environment from an early age. Special attention is given to integrating environmental content into preschool educational activities by applying observation, experimental learning, play-based instruction, project-based activities, and practical tasks that encourage active participation. The paper presents a methodology for organizing experimental research aimed at assessing the effectiveness of environmental education in improving children's ecological knowledge, emotional appreciation of nature, and environmentally responsible behavior. Evaluation criteria and indicators for experimental and control groups are also described. The findings demonstrate that the systematic application of innovative pedagogical technologies, interactive teaching methods, and close cooperation with parents significantly improves children's environmental competence, cognitive engagement, and value orientations related to nature conservation. The proposed methodological recommendations may contribute to enhancing environmental education practices in preschool institutions and supporting the formation of environmentally responsible future citizens in accordance with the principles of sustainable development.
