The learning strategy was built up by a sequence of activities that involve History of Science and experiments, put in a course that had as a base the proposal of the Group of Redevelopment of Physics Teaching (GREF). We have used as the conductor wire of our research the development of thermo dynamics since the development of the first thermo machines, passing by the Industrial Revolution and the evolution of concepts of warmth and temperature. The learning strategy was applied to a group of second grade of secondary school in a public school in Mossor? (RN). By doing these activities we tried to become the concepts, which are part of thermo dynamics, more meaningful to the students. We have estimated that the application of the strategy has represented some profits to the students of the group, concerning to learning of laws and concepts of thermo dynamics (specifically the concepts of warmth and temperature), as well as what it is referred to the overcoming of its initial conceptions / Este trabalho investigou as concep??es alternativas apresentadas por alunos do Ensino M?dio, em rela??o aos conceitos de calor e de temperatura, objetivando a elabora??o e aplica??o de uma estrat?gia de ensino a partir do diagn?stico levantado das concep??es presentes nos estudantes. A estrat?gia de ensino foi constitu?da por uma seq??ncia de atividades que envolvem Hist?ria da Ci?ncia e experimentos, inseridas num curso que teve como base a proposta do Grupo de Reelabora??o do Ensino de F?sica (GREF). Utilizamos como fio condutor de nosso trabalho de pesquisa o desenvolvimento da Termodin?mica, desde o desenvolvimento das primeiras m?quinas t?rmicas, passando pela Revolu??o Industrial e a evolu??o dos conceitos de calor e de temperatura. A estrat?gia de ensino foi aplicada a uma turma do segundo ano do ensino m?dio de uma escola p?blica da cidade de Mossor? (RN). Procurou-se, com as atividades, tornar os conceitos que fazem parte da Termodin?mica mais significativos para os alunos. Avaliamos que a aplica??o da estrat?gia representou ganhos para os estudantes da turma, em termos do aprendizado das leis e conceitos da Termodin?mica (especificamente dos conceitos de calor e de temperatura), assim como no que se refere ? supera??o de suas concep??es iniciais
