The present work concerns on planning and development of a proposal for teaching Physics, based on the Theory of Conceptual Fields of Vergnaud, developed from the theme tobacco production and implemented in the classroom, with the support of teaching material aided by audiovisual resources, based on the model of three teaching stages by Delizoicóv and Angotti. The proposal aimed the network conceptualization development in the conceptual field of Thermal Physics. The concepts treated in that proposal are temperature, heat, thermal expansion and contraction, thermometers of liquid in glass, conduction, convection and heat irradiation. The support material, developed in this paper, consists of a teaching module that comes with an own production digital video disk. The proposal was applied in a group of twelve students from the second grade of high school, from Escola Estadual de Eduacação Básica Padre Benjamin Copetti, Sobradinho, RS, from September to November 2008. In this period, it was tried to identify their potential and limitations, to assist the students, both the learning of physical concepts as the building of relationships between concepts, and know the importance of the issue tobacco production, in the student s opinion, and identify possible relation they have built between concept and knowledge, involved in the theme chosen. An analysis of this experiment was made from the content of messages, obtained from the instruments of data collection type questionnaire, terms of field (from students) and images video shot. The results indicate that students seemed to be involved and active participants in the tasks presented, indicating acceptance in the methodology of work. During the interaction with the tasks, some students identified both the presence of the same concept in different physical processes, as the same process that involves more than a physical concept, what can be understood as evidence of student development in the conceptualization system of some concepts in the field of Thermal Physics, from processes of reality. The obtained results with only a small group of students, are indicative that the proposal has potential to develop the student conceptualization network, although it is understood that for some students, the tasks given were not enough to develop the construction of physical concepts and their inter-relationship in the processes of reality.
