Experiemental classes constitute in an efficient teaching strategy due to their motivating nature. On a preparatory course for Exams and “Vestibular” exams, the teaching of a wide range of contents in a short period of time stands out. In this context, this work aims to investigate the contributions and limitations of the use of experimentation in Chemistry classes of a pre-university course in Rio Branco/Acre. With a qualitative and exploratory research approach, a semi-structured questionnaire was used in the collection of data, applied after 17 classes, and in each one, different demonstrative experiments were carried out. The results indicate that the use of experimentation contributes to a better understanding of the subject and their concepts and the students justify this importance, considering that the explanation becomes clearer. However, regarding the limitations, the students pointed out insufficient course load and inadequate space, stating that this type of teaching method is not traditionally expected in preparatory classes.
