Content analysis is one of the important research methods that can be used to systematically and objectively study the characteristics of textbooks. The aim of the current research is to analyze the content of chapter 3 of the 10th chemistry book. In the present research, chemistry book 1 was considered for analysis from the point of view of its compatibility with the national curriculum. According to the frequencies obtained, the most attention has been paid to the field of science (32%) and the least attention to the field of ethics (8%).
