The reading topics of the department were determined by three classes in grades 7-8-9, related the topics to each other and analyzed separately. In topic-based assignments, research papers provide many opportunities to explore the area and gradually move from simple to complex. Therefore, in school areas comments were given on the methodology for conducting research work, instructions on the use of necessary items and equipment for conducting experiments and safety rules. Based on the research conducted using the manual, presented a diagram of the level of knowledge acquisition by students.
