The teaching of Science in all its aspects enables the acquisition of students' natural science competencies through experiment. An experiment motivates students to a research approach, makes the teaching process more fun and interesting, and contributes to the development of many skills. Thus, the aim of this paper is to investigate the presence of experiments in textbooks and workbooks for the subject Science written in according to the Curriculum (MSES, 2006) and the Subject Curriculum of the Science (MZO, 2019). Furthermore, the attitudes of teachers about the representation and conduction of experiments in science teaching were examined. The results of textbooks and workbooks research indicate an increase in the number of experiments from the first to the fourth grade of primary school. Textbooks and workbooks written in according to the Curriculum of the Science for the 1st grade contain several experiments and research tasks. Teachers believe that experiments can be conducted in primary education with students, and that their implementation does not depend on the introduction of curricular reform in schools, which indicates that teachers conduct experiments depending on the capabilities of the school and their initiatives. Experiments are conducted mostly by teachers in the classroom, less by homework, and less than half of teachers use the presentation of the experiment through electronic simulations and materials.
