The most important characteristic of teaching science in general and chemistry in particular is the laboratory and practical experimentation, as the laboratory is considered the "beating heart of science education". It is necessary to emphasize the important role it plays in teaching science, facilitating learning, acquiring it by working, and maintaining its permanence and continuity. This is what all educators emphasized in terms of interest in experimentation and laboratory work, and it is necessary for teachers to devote as much of their time as possible in an attempt to achieve complementarity between the theoretical and practical sidesا Therefore, the research problem lies through answering the following question: What are the obstacles to using the laboratory in teaching chemistry from the teachers' viewpoint? The research aims to identify obstacles to the use of the laboratory in the teaching of chemistry from the point of view of the teachers themselves.
