This work presents a research entitled "Alcoholic fermentation: a didactic sequence for the teaching of Chemistry in the third year of high school", which aimed to develop a didactic sequence for the teaching of the alcohol function from alcoholic fermentation in the last year of high school. average. So, it was necessary to organize the research in three stages, namely: i) Articulate the concepts of Alcoholic Fermentation, Didactic Sequence; Chemistry teaching; and CTS Approach; ii) Execute the didactic sequence referring to Fermentation; and iii) Analyze the data from the execution of the didactic sequence. Therefore, the didactic sequence was designed and elaborated based on the CTS Approach. In order to contextualize the content “Function Organic Alcohol”, it was decided to emphasize the most common alcohol, ethanol, opting to use alcoholic fermentation as a topic that generates learning in the didactic sequence. In this way, the research, of a quanti-quali character, was carried out at Escola Estadual Professora Diana Pinheiro, where questionnaires and the didactic sequence were applied in a class of 32 students, in order to evaluate the effectiveness of the proposal. As a result, the post-intervention questionnaires showed more elaborate explanations by the students and a percentage of 92.5% of satisfactory answers. In addition, the contribution of alcoholic fermentation was well evaluated by the students, noting that the theme was a differential in this result.
