The paper presents the importance of outdoor activities (in nature) and different possibilities of using natural materials in art activities in kindergarten. Special emphasis is placed on materials from nature that we can use in art activities: by exploring their characteristics and possibilities, by using them as an incentive/template for observation and research that leads to creativity in art materials, and as alternative art material, which children express themselves artistically. After presenting the attitudes and results of research by pedagogues and other scientists on the importance of learning in nature, the importance of using natural materials, but also learning about nature through art activities with children (ages 3 to 7), one example from practice is presented. Based on several examples from the art project that we realized in kindergarten, we presented possible ways of using natural materials. We conclude that the use of natural materials and the realization of artistic activities in nature (kindergarten yard) is of great importance, because their potentials enable the development of creativity in children, where through practical manipulation of natural materials children learn about the world around them and develop a positive attitude towards nature. Natural materials encourage creative thinking in children, who, by exploring their possibilities, through trial and mistake, come to longer-term knowledge.
