The term “popular scientific topics“ in the cognitive picture book in this paper refers to all picture books that are educational in nature and relate to topics related to various fields of science such as biology, physics, geography, history, mathematics, astronomy, etc. Due to insufficient research, lack of information and knowledge of the same, picture books are still often underestimated and are not considered "serious reading material". Publishing production in the last few years indicates an increased interest in the production of original, but also translations of quality picture books in Croatian. In addition to the picture books for adults, the number of titles that are not exclusively intended for preschool children has also increased. This paper investigates the possibilities of using the so-called cognitive picture books with a popular scientific topic in the teaching of lower grades of primary school. The characteristics of the cognitive picture book and the appropriateness of its use in teaching in the lower grades of primary school will be studied. It will also be investigated how many picture books have been published in the last five years (2015-2019) and what share of picture books we consider cognitive with a popular scientific topic. The research will be conducted with the help of an analysis of the list of good books for children, youth, and parents on the website of the Croatian Library Association for the period previously mentioned.
