Abstract

The educational system has been going through transformations with regard to science teaching, since it has been restructuring itself, especially in its methodology, which is the approach adopted in the classroom in the midst of reflections. Nowadays, there is a search for a teaching in which the student is the protagonist of his own learning. Regarding teaching methodologies, this work was designed in the construction of an investigative teaching sequence-SEI, emphasizing environmental issues. The target audience chosen will be students of the seventh year of elementary school, SEI was structured in five pedagogical meetings. The present study aims to identify the main substances responsible for atmospheric pollution and how they cause acid rain within an SEI. A research with a qualitative methodological approach was chosen. The results obtained in this study indicate that the activities developed through SEI, aim to contribute to the construction of knowledge of the students, in a progressive way, giving evidence of a contextualized learning, focused on the formation for citizenship, since it is important to develop scientific practices in schools for the construction of proposals for explanation and evaluation of evidence in argumentative practice.
