The aim of the study is to examine informational children's picture books prepared for preschool children in terms of scientific process skills. The study was conducted using the document review method, one of the qualitative research methods, and descriptive analysis method was used in the analysis of the data. Within the scope of the research, 18 books in the "Science Solves It" series prepared for preschool children by TUBITAK publications were first analyzed in terms of scientific content, and then analyzed according to 17 scientific process skills under the headings of basic process, causal process, and experimental process skills as a result of the scans in the field literature. As a result of the research, it was found that informational children's picture books in the Science Solves It series from TUBITAK publications were mostly prepared for the field of life science within the framework of science standards, and they were insufficient in terms of providing a scientist image to preschool children and presenting historical knowledge of science. In terms of scientific process skills, it was found that basic process skills were used more. Among the basic process skills, it was found that the communication skill and observation skill were included the most, while the measurement skill and the use of number/space relationships skill were included the least.
