Química e meio ambiente: estimulando o protagonismo dos estudantes na execução de um projeto de compostagem no Colégio Tiradentes - Maceió - AL

Abstract

A new proposal for secondary education validated in the new National Common Curricular Base, BNCC, enacted in 2018 and with a deadline to be effective in 2022, proposes to the student how to be active in their educational training, developing skills and abilities during the course of secondary education in addition to of your educational background, goals and directions in your life. In the new high school, the innovative discipline known as Life Project was included, which proposes training that includes the development of competences in the areas of knowledge and socio-emotional skills, in addition to directing their role in society and the environment in which they are inserted. Based on the new educational proposals, an action research was carried out, with the objective of putting into practice a project related to the treatment of urban solid waste, based on the investigation of biogeochemical cycles and environmental pollution issues. The proposal made was the execution of a project, where high school students were protagonists, in the planning, development and execution phases under the supervision of the teacher-researcher. The research was approved by CEPE - UFAL and all pedagogical practice took place at Colégio Tiradentes, belonging to the State Education Network, in the State of Alagoas in the municipality of Maceió, from August 2021 to June 2022, with students from the first year of high school. This research aimed to collaborate with the teaching/learning processes based on projects in line with the new BNCC, the Life Project and the training itineraries of the new high school. The research was exploratory in nature, where the referred students, through questionnaires. Atmospheric gases, micro and macro nutrients, carbon cycle and nitrogen cycle could be worked on in a practical way with an educational project led by students; recognizing that air is a mixture of gases, identifying its composition, and discussing natural or anthropic phenomena that can alter this composition, following BNCC skill EF07CI12. The project culminated in the development of a composttype biodigester associated with a vertical garden related to the chemical compounds present in this work, in particular the cycles of carbon, nitrogen and environmental pollution.
