Teaching Chemistry Proposal for Integrated Agricultural Technical Course on the Theme of Contamination by Pesticides and Heavy Metals in a Water Reservoir

This paper presents a proposal for Teaching Chemistry (TC) with a focus on Environmental Education (EE) using the three pedagogical moments (3MP) as a didactic strategy and a local theme on the problem of environmental contamination of a water supply reservoir by pesticides and heavy metals. The research was carried out with vocational students from the Integrated Agricultural Technical Course at a public school in the city of Ponta Grossa, Paraná. The work used scientific articles, television reports, software for data collection and, at the end, the students were encouraged to produce an e-mail to send to the local authorities about the actions being taken to deal with the problem of contamination. The results point to the need for chemistry classes to effectively articulate local content and themes on environmental contamination, with a view to critically training agricultural technicians, which will enable them to reflect on their rights and duties as citizens. It was found that there was a significant improvement in the understanding of chemical concepts and criticality in relation to environmental problems. Thus, the use of the 3MP and an environmental theme would enable technicians to be trained as holders of scientific knowledge and professional skills in tune with the social and environmental reality.
