The aim of this study is to investigate the interdisciplinary content of the logarithm, to serve as a motivation for learning in a high school class. Literature search was undertaken to produce this work indicates the possibility of the presentation of logarithms of contextualized and interdisciplinary way. Using some facts from the history of mathematics teacher can give the student more sense to this content and applications. In this regard, we point out some practical applications of logarithms in the study of natural phenomena such as earthquakes, and the use of logarithms for the calculation of pH and applications in acoustics. Some suggestions of activities, in which some were applied to two groups of high school (NEJA), teaching young people and adults, the West Zone of the City of Rio de Janeiro are cited. First, we apply an initial questionnaire before the activities by assessing the students' prior knowledge about the facts of the history of mathematics and the relationship of mathematics and other sciences. At the end of the implementation of activities, we apply a final questionnaire assessing whether or not the activities motivated students in pursuit of knowledge. At the end we report the experience and opinions of students. === Esse trabalho foi realizado com a finalidade de reorientar o professor de matem?tica na amplia??o de sua abordagem did?tica no ensino de logaritmos em sala de aula. O objetivo desse trabalho ? investigar a interdisciplinaridade do conte?do logaritmo, para que sirva de motiva??o para o aprendizado em uma turma de ensino m?dio. A pesquisa bibliogr?fica realizada para a produ??o deste trabalho apontou a possibilidade da apresenta??o de logaritmos de forma contextualizada e interdisciplinar. Utilizando alguns fatos da Hist?ria da Matem?tica, o professor pode dar ao aluno mais sentido a este conte?do e suas aplica??es. A esse respeito, destacamos algumas aplica??es pr?ticas de logaritmos em estudo de fen?menos naturais como terremotos, al?m do uso de logaritmos para o c?lculo de pH e aplica??es na ac?stica. S?o citadas algumas sugest?es de atividades, nas quais algumas foram aplicadas em duas turmas de ensino m?dio (NEJA), ensino de jovens e adultos, da Zona Oeste do Munic?pio do Rio de Janeiro. Primeiro, aplicamos um question?rio inicial antes das atividades, avaliando o conhecimento pr?vio dos alunos sobre os fatos da hist?ria da matem?tica e a rela??o da matem?tica com outras ci?ncias. Ao t?rmino da aplica??o das atividades, aplicamos um question?rio final, avaliando se as atividades motivaram ou n?o os alunos na busca do conhecimento. Ao final, relatamos a experi?ncia e as opini?es dos alunos.
