It is presented a didactic proposal with the aim to analyze the evolution of radiation models, create a more accurate vision of science and the construction of scientific knowledge than the one which is very common among teachers and students, and it pretends to construct a radiation model more related to nowadays¿ science, where the properties of the wave and particle models join to become a new quantum object with dual behavior. It is analyzed the sequence of models proposed through history in four activities, to explain the nature of light, from Newton¿s particle model to Huygens and Young¿s wave model, ending in the discussion about Einstein¿s photon model and the photoelectric effect. Keywords: model building, didactic proposal, photoelectric effect, photon, model of light
