At the earliest age, children have contact with something from the above. Most parents prefers give children mobile phone just to be carefree. In this way, children's imagination and the need for research are absent. For this reason, as many research-cognitive activities as possible should be introduced into kindergartens, which will be written about in this paper. Educators must carefully design various activities through which children will be approached in the best possible way. There is a wide spectrum of materials that educators can use during these activities. It is necessary for the educator to have a lot of knowledge and experience in order to provide children with the best possible access to research and cognitive activities. There are a number of advantages that such activities bring. In addition to the activities, language expression, mathematics, physics and many other sciences can be practiced, which can be useful to children in later life and education. It is also necessary to organize the best possible environment that will attract children of all ages: from the youngest to older children. The paper was written on the basis of various research conducted in different preschool institutions and kindergartens, and the results are written throughout the paper.
