The importance of lab studies is especially evident for science courses such as physics where abstract concepts are frequently used. The fact that the students comprehend the experiments better, and that they are better organized while doing the experiment will ensure that they will be more interested in the laboratory and thus in the topic. For this reason, it is likewise important to develop new techniques to use in lab activities. Guidelines for laboratories are of great help for students in comprehending and performing the experiment. It is an important necessity that the guidelines should frequently be renewed and that adjustments should be made to meet the changing needs of students. In this study, task analysis method is covered to be used in experiment guidelines. In this method, the steps to be followed by the student are provided on a diagram, and through cycles, missing or forgotten steps, if there are any, are determined. Thus, the students can see the whole of the experiment with all of its steps with the help of the diagram, and by relating it on the diagram; they will be able to understand What they do, and Why they do it
