The diversity in the types of vegetation, Brazil is the second largest biome Cerrado, occupying 25% of the country, surpassed only by the Amazon. In Minas Gerais, the Brazilian state has about 10.3% of its area the Cerrado vegetation, covering mainly areas of the Upper and Middle Jequitinhonha. The flora of the cerrado has several fruit species with high potential for agricultural use, which are traditionally used by local people, and the fruits have high levels of sugars, proteins and minerals. Among the great diversity of plants and fruits present in the cerrado is the Eugenia dysenterica, popularly known as cagaita. The fruit is globular yellow color when ripe, slightly acid and can reach up to 4 cm long and up to 5 cm diameter. The work here exposed was led initially to a survey of state schools that have high school in the city of Sete Lagoas-MG. After this survey was chosen for the project development a nearby school of the Federal University of Sao Joao del Rei (UFSJ-CSL) for viability of the project and in which direction proved to be very available. 3rd year high school classes were chosen, totaling 55 students, selecting the students who had greater knowledge of the concepts studied and shown interest. Various activities with students have been developed, one of which is the application of a questionnaire in the first meeting, which enabled us to identify where the problems thereof. a booklet with texts followed fixation exercises and illustrative images on each topic worked in class and the students images developing the proposed project activities was developed. This study aimed to use a fruit of the Cerrado, cagaita to perform fermentation and subsequent distillation, to promote ownership of the concepts of chemistry, biochemistry and biotechnology in high school students. Through the questionnaire at the end of the project, it was possible to assess the relevance of their work and the impact on the training of students. The study proved to be very promising for the students and the school, where probably, future students of the University. It is important to emphasize that the development of the project was very promising because it allowed greater interaction of students with dynamic classes, practical and contextualized, allowing a greater learning of them.
