From chemistry to the breath of life: investigating chemical reactions and unraveling the mysteries of the lungs in early childhood education

Abstract

This practice report was carried out in 2023 with the aim of encouraging students to take part in the “Me, Scientist in the World” essay competition, promoted by the Taguatinga regional office, as well as involving them in the Science Circuit for Public Schools in the Federal District. The project provided the children with an engaging and practical educational experience, combining learning and playfulness through two different stages: chemical experiments and exploration of the respiratory system. The main objective was to introduce basic chemistry concepts, focusing on the bicarbonate-vinegar reaction, while also looking at how the lungs work. In the methodology used, the children took part in practical experiments where they directly observed how bicarbonate and vinegar react to inflate balloons, offering an initial understanding of chemical reactions. In addition, visual and practical activities were conducted to explore the respiratory system, allowing the children to relate the process of filling and emptying the lungs to the previous chemical experiment. The results achieved included awakening the children's scientific curiosity, a basic understanding of chemical reactions and a familiarization with how the lungs and breathing work. This project aimed to lay a foundation for future learning, thus contributing to the students' educational and scientific development.
