The aim of the paper is to encourage children's introduction to geology as an integral part of the environment, or more precisely, the nature that surrounds us. At the beginning there is a brief overview of geology as a natural science, its historical development and the main geological disciplines, especially those used in the paper. In addition to this, there is also a review of the activities that have been carried out, including international experiences with geology in kindergartens as well as Croatian experiences with geology in elementary schools, museums and especially in kindergartens. The research included in the paper was conducted in the kindergarten “Iskrica" in Zagreb. A geological display was used in the research, which was composed of samples of fossils, minerals and rocks. The goal of the research is to explore the children’s introduction to geological science as a part of natural sciences. The research has been carried out by examining their prior knowledge through introductory questions, trying to introduce them to geological science through activities and then checking their potentially newly adopted knowledge through further activities. The research was conducted through two activities over two days. The first activity was carried out in such a way that the children approached the geological display lead by their own interest and asked questions about the collection, whose parts they could also take, touch etc. After that, the children worked with clay and drew. The second activity was conceived to be conducted through teaching, but the children did not react well to this method so it was abandoned. Following that, the display was shown to the children accompanied by a story, in which they participated by asking questions, suggesting which samples should be included in the story, etc. In addition to this, they could also browse and touch the geology display as well as ask questions about it. At the end of the activity, the children worked with clay, drew and played an interactive game on the subject of the activity and the display. It can be concluded that it is possible to successfully introduce children to geology as a natural science. It is also evident that it is also possible to introduce children to such a science using different work methods. Except for the geological themes used in this paper and the already carried out activities, these themes can be further expanded.
