Modelization has a significant role in the teaching of science in general. However, there are few studies related to this topic. In this paper we will identify the role given to modelization in science teaching, particularly in biology teaching. To that end, we present an analysis of one activity, developed in a second grade class of high school, with the purpose to work the human body theme through the construction of representational models. With such activity we wish to overcome the traditional presentation of the human body in textbooks, providing students with a comprehensive understanding about what it is and how it is structured. Finally, we believe that modelization is an effective possibility for the teaching-learning process in biology.
