In this work, we seek to identify the contributions of experimental investigative activities to the development of the scientific ability to propose hypotheses in undergraduate Physics and Chemistry students. We conducted a qualitative research with 20 participants of the courses of an Federal University in the North of Brazil. By a workshop with investigative experimentation in the laboratory, the students elaborated their hypotheses and carried out the experiments. Data were collected through written activities of each activity performed and interviews that were analyzed, respectively, by rubrics and Textual Discursive Analysis. We found that experimental investigative activities are a promising alternative to develop the ability to elaborate hypotheses, however the research shows that this skill needs to be worked on by activities with a longer duration.
