The present work deals with didactic intervention that sought to unite the concepts of radiations of the electromagnetic spectrum to the technological advances present in the life of the individuals. For that, the teaching method called Case Studies was used. This was presented with a socio-scientific character in a Science Technology, Society and Environment (CTSA) approach, with the objective of promoting in the student a critical look at their reality, developing a responsible social attitude based on questions related to their daily life . The research presents qualitative character with a focus on student learning from the point of view of Vygotsky's theory of cognitive development. The study resulted in the elaboration of an Educational Product with the theme of Radiation of the Electromagnetic Spectrum, in the context of Cases presented to the students. Through a didactic sequence that includes the reading of texts that allowed a debate and discussions about the theme, elaboration of conceptual maps, realization of experiments of low cost and resolution of theoretical and formal questions, conceptual subsidies were provided so that the student found the solution of the problem raised in the Case Studies. The diversity of instruments made possible a dynamism in the classes, promoting the interaction of the students through debates and activities that made the concepts taught more meaningful. The study was carried out in Physics classes of the 3rd year of High School, according to what was foreseen for the minimum curriculum of the state of Rio de Janeiro. The data collection was carried out during the application of the described instruments and resulted in indications that the proposal was relevant to the learning of the pertinent themes.
