The goal of this paper consisted in an elaboration of a didactic research, using a rotation for stations to assist the process of learning in thematic stages of treatment of water for students in the high school. The methodologic approach of this paper was qualitatively done, through research; 23 students participate voluntarily with this work, and the instrument to collect the data was a quiz made with 21 objectives and subjective questions. The classroom was divided in four stations with different activities, the students parted in groups and they had 20 minutes to accomplish these following activities such as virtual game, CTSA reading and the experimentation, after the timed time, the groups rotate simultaneously to the other stations. The work also evaluated the participation and the students’ expressed feelings. Analysis and evaluation of the participation in the quiz, were a primordial instrument for the obtained results in this research, and it shows that resort to active methodologies is important to motivate, instigate, mediate and also brings the individual responsibility in their teaching and learning process. The results showed how much the pandemic, provoked by the virus SARS-COV-2, potentialized the inequalities related to the access of school environment, the difficulties shown by the students were: demotivation to the remote teaching approach, accessibility to digital, responsible unemployment (obligating some of them to help in household income).
