This poster describes the experience of a research on the topic of energy matrices carried out by high school students. The proposal was to use the theme energy matrices to conduct an interdisciplinary study on sources of electricity, addressing technical, historical and environmental aspects. It was intended through the chosen theme to relate science content covered in high school with the said theme with regard to matters of industrial development, new technologies and environmental impacts. The specific forms of electricity generation under study were: hydroelectric, thermal, wind, solar photovoltaic and heliothermic energy. The discussion of energy matrices is directly related to the impacts generated by different forms of electricity generation. The emission of gases that cause the greenhouse effect by power plants and the environmental demands of hydroelectric power plants configure contemporary issues that should be present in any discussion on development strategies, since these two sources are characterized as the main forms of generating electricity today. Meanwhile, renewable energy such as solar photovoltaic and wind, are structured today as viable sources from the technological and economical standpoint. Several authors as Mortimer (2002), Bazzo (2007.2011), Delizoicov (2009) and Chassot (2003) advocate the application of the STS approach in the development of science education in primary and secondary education as a way to enhance the educational process. The proposed STS approach in education is to study scientific contents of physics, chemistry and biology from technological applications and impacts generated by such applications, using general themes (water, waste, pollution, energy) as catalysts in the educational process. The study of the characteristics of technology for generating electricity occurred through the linking of educational content with technological applications, taking as reference the analysis of environmental and social impacts. The implementation of the project consisted on the preparation of the demonstrative models of the themes, being those an artistic model and a technical scale model. The public communication of the project involving Science and Technology took place through participation in school fairs, conferences on energy and events promoting science and technology
