Our project consists of 5-6 year old preschool students. It is an educational project that includes science activities in which our students will learn the inventions they choose in line with their inventors and interests through in-class activities such as art, games, science experiments, mathematics, music and stories. It is the period when the child's acquaintance with science begins, he interacts with his natural environment, and his characteristics such as curiosity, discovery, examination, design and questioning reach their peak. The behavior of a child when learning something is similar to the behavior of a scientist. Because both ways of learning are based on examination and research. Therefore, “the child is a little scientist”. The research carried out by the child with his own efforts is as valuable as the work of a scientist, and the results he reaches are just as important (Soylu, 2004). This is a project in which we will complete our work with this thought.
