Chronobiology brings one of the most important contributions related to time: the notion of variability of biological functions throughout the 24 hours of the day. Thus, the objective of this project is to develop a didactic sequence in which there is the protagonism of high school students in their own learning to teach in a practical and applied way the chronobiology and the circadian cycle. The sample consisted of 40 students between 15 and 16 years old, of both sexes, regularly enrolled in high school in a public school in the city of Itaúna / MG. The didactic sequence was distributed in 10 modules, being a dialogue class of initial diagnosis, orientations on the stages of the project, directed research in group, application of Questionnaire, orientation and application of Sleep Journal, application of tests to identify the chronotype, group of discussion for analysis of results for identification of the Chronotype, development of the educational brochure of Circadian Cycle, presentation of the theme in the Science Fair of the school and bimonthly evaluation. For the practical realization and facilitation of the data recording dynamics in the identification of chronotype, the volunteers were randomly divided into three groups for the execution of the tests. The results showed that 22 students performed the physical tests at three different times of the same day at 7:30 p.m., 13:30 p.m. and 19:30 p.m. (S3), respectively, while the others in the class participated as monitors of the execution of the tests. the preparation of the educational brochure. On that day, the anthropometric measurements, the Yoyo test and the Subjective Effort Perception Test (PSE) were carried out by the students themselves in a monitored manner. These tests were replicated at other times (S2) and (S3) always in the same order as the first situation (S1). Part of the results obtained in the identification of the chronotype served as the basis for the presentation at the School Science Fair. The results showed that the physical test may be more suitable for adolescents in identifying chronotype.
