    This work analyzes the development of an investigative didactic sequence (SDI) on acid-base, aimed at students of the 3rd year of high school, which aims to promote the active participation of students and help them in learning difficulties about these concepts, faced in the period of the COVID 19 Pandemic. The sequence was developed considering some stages of research teaching, such as: presentation and resolution of a contextualized problem, elaboration of hypotheses, seeking the passage from manipulative to intellectual action, in relation to the construction process knowledge and problem solving by students, and the construction of new explanations to solve the problem. The planned activities were constituted as a data collection instrument, and the students' productions as a record for data analysis, which were analyzed based on analytical categories, elaborated from the chemical knowledge about acid and base, and aspects of teaching by investigation. The results show that most students had an understanding more grounded in school scientific knowledge, about the concepts worked during and after the development of SDI. It is concluded that the use of an investigative didactic sequence to address the topic of acid and base, was configured as an efficient didactic strategy for the process of knowledge construction by students, in Chemistry classes.
