To facilitate the science learning, you need to investigate the design of didactic strategies alternatives, and seeking to establish linkages between the pedagogical use of the computer and the laboratory of scientific practices, such as tools of pedagogical support for the development of the teaching-learning process. The present research focused on the design of strategies for teaching and learning, through the completion of didactic sessions, of chemistry, articulating it is pedagogically the laboratories of scientific experimentation and computer, to facilitate, together with the students, the significant learning of the knowledge of organic chemistry, specifically the light hydrocarbons. Disembarked on the theory that meaningful learning of Ausubel, the conceptual map of Novak and the proposal of constructionist Valente. There was the use of educational software Jmol, praising the collaborative construction of knowledge, skills and abilities. Such actions were carried out with the participation of 11 students, of the 3rd year of secondary education in a public school in the municipality of Beberibe, designed in four stages: preliminary, theoretical and experimental, practical-virtual and collaborative. The methodological approach of the research was qualitative and is characterized as exploratory research. The data obtained by the use of questionnaires, and observations of the teacher-researcher allowed to analyze and conclude there is evidence of the development of creative ability, collaborative, which the students are motivated to develop new skills and build new knowledge through the realization of pedagogical practice of experimentation of organic chemistry and use of software Jmol. The experiment of the production of ethno in step theoretical-experimental was a way of working in a more clear, dynamic and collaborative signification and construction of knowledge. The use of pedagogical and collaborative software Jmol in the stage-practical virtual and conceptual map in the stage collaborative enabled students to develop an understanding more facilitator of the concept, writing, representation and visualization in three dimensions of compounds of light hydrocarbons.
