Educação ambiental por meio da compostagem de resíduos orgânicos no centro estadual de tempo integral Deputado Pinheiro Machado localizado em Cocal-PI

Abstract

The growth of urban populations and excessive consumption generate large amounts of organic waste, making it one of the biggest environmental problems today. Discarded in dumps and landfills, these residues lead to the release of gases that contribute to the greenhouse effect, soil and water pollution and attract disease-transmitting animals. Composting is one of the ways to treat these organic wastes, preventing them from being sent to landfills. In this context, this work aimed to work on environmental education in chemistry classes, using the composting of organic waste from school lunches as a topic that generates knowledge and as a significant learning tool. The target audience was second year high school students from the Centro Estadual de Tempo Integral (CETI) Deputado Pinheiro Machado, located in the municipality of Cocal-PI. The research was carried out in three moments, the first developed through an expository thematic class, the second through the construction of a homemade compost bin and the third through a conversation circle. The activity developed allowed students to learn chemistry through discussions about the decomposition of organic matter and its effect on the intensification of greenhouse gases, in addition to raising students' awareness of the damage that organic waste causes to the environment
