This work is the result of a project developed on the Araguaia and Garças rivers, an urban perimeter of the city of Aragarças in Goias state and Barra do Garças and Pontal do Araguaia in Mato Grosso. Our objective was to outline the teaching of chemistry from a real and local problem, demonstrating in the process the importance of chemical knowledge in the reading and interpretation of phenomena arising from anthropic action in nature. The research is mixed due to the association between quantitative and qualitative data. Our data comes from the context revelations (rivers) and the analyzes, which had as reference the method NBR 10.739 of the Brazilian Association of Technical Standards (ABNT) and the technique of atomic absorption spectrometry (EAA). The evidence during, and the reports after the end of the research, served as a basis for the verification of student instrumentalization, showing the importance of the appropriation of chemical knowledge and of context in scientific literacy.
