This paper describes an investigation 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. The objective was through the chosen theme to interweave science content covered in high school with the theme focusing on 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. The implementation of the project consisted on the preparation of the demonstrative artistic and 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.
