At high school‟s level, Biology appears among the disciplines with a huge number of contents, being some of them presented as difficult to teach and understan, once they contain a large number of concepts and technical terms. In this research, we emphasized the importance of contents‟ approach through teaching by experimentation, because this didactical strategy is showed as an important contribution in learning and teaching process. This work contains the story of a didactical experience developed in school environment, whose general objective was the analysis of experimental classes‟ success in Celular Biochemistry contents‟ approach. The research was conducted in Monsignore José da Silva Coutinho State High School, which is located in the town of Esperança/PB. The instruments of data collection consisted of a questionnaire and an interview script. The data resulted through investigation received a descriptive- qualitative treatment. From the answers obtained from the questionnaires and interviews‟ transcriptions, it was categorized the themes spoken by the participants. The categorization was made using the thematical analysis described by Bardin (2011) as a tool. In the purpose of achieving the objectives proposed to this study, categories‟ analysis were built - previous knowledges, conceptual rebuilding, perception and comprehension. The results showed that, with the application of experimental classes, the students could rebuild concepts from previous knowledges. We observed a better comprehension of the students about Celular Biochemistry‟s contents. About the identification of food rich in carbohydrates, proteins and vitamins, we observed that, after this intervention, the students presented a broader largeness of examples. Through teaching by experimentation, we could observe a better comprehension of the students about vitamins, proteins and carbohydrates‟ functions. This work leads us to believe that teaching by experimentation presented as an important strategy in teaching Celular Biochemistry‟s contentes, contributing especially to conceptual rebuilding. The results obtained can contribute as a subside to continuous formation teachers‟s courses, taking as a basis the didactical experience developed in school environment.
