Today, science and technology are more present and more developed than ever, and yet fewer and fewer young people choose to study and develop their profession in this direction. Students' scores on knowledge assessment tests in fields of science and mathematics are below average, so official education documents, both European and Croatian, emphasize the importance of gaining competences for lifelong learning, and one of them is scientific literacy. Popularization of science and scientific literacy should be carried out from an early and preschool age. Children have an inborn curiosity and need for understanding the world, which research activities nurture, and they encourage children to think and conclude through experiential learning. Numerous scientific topics can be carried out in kindergarten in a manner appropriate to age and abilities of children and in different ways: through play, project, action research, etc. However, many preschool teachers find that they do not have enough knowledge and skills, as well as motivation to carry out science activities in kindergarten. Early stimulation of interest in science and technology is not exclusively related to the kindergarten. There are more and more organizations and projects trying to bring science closer to children and encourage them to engage in it. Unfortunately, they are not affordable to all children because they are mostly not free of charge and some of them are not suitable for preschool children. Some authors argue that children and scientists have many things in common, so science certainly needs to find its place in preschool educational practice because "being a child means being curious, and being a scientist above all means staying a child" (Milotic, 2013: 16).
