In this work we discuss both phenomenological and theoretical aspects of knowledge in Physics and the role of models as bridges between them. As far as teaching is concerned, one notes that theories taught to students normally bear a very little relation with phenomena in daily life. Therefore we emphasize the importance of using models as tools in order to promote meaningful links between the abstract world represented by theories and the real world, represented by phenomena. With the purpose of stressing the different nuances of physical knowledge, we approached a model, known as Drude model, focused on introductory courses of electromagnetism in higher level. This example describes the interaction between electromagnetic waves and matter. The main goal is to make explicit, as clearly as possible, the links between physical ideas, represented by electromagnetic theory, and the real world, so that physics teachers and students may have an epistemological and rich relationship with Physics.
