Proposta de um manual de práticas de química utilizando materiais do cotidiano para a Escola Diferenciada de Ensino Fundamental e Médio Índios Tapebas

Abstract

Chemistry is a natural science that encompasses two important aspects: theory and practice. The theoretical aspect is the moment at which the contents are discussed through an explanatory way; in practice, otherwise, these contents are developed experimentally. Considering this fact and the research developed to the elaboration of this work in an Indian school, it was noticed that the contents of the Chemistry subject in this very school were only theoretically taught, without the conduction of practical classes. For this reason, nowadays, students belonging to the Differentiated Indians Tapebas Elementary and High School, felt unhappy because they were not covered with practical lessons. About a study developed in the mentioned school, a research was conducted in which, through questionnaires, the main grievances of the students were verified. One of them is the lack of a science or chemistry lab in the Indian school. Therefore, it was verified that both teachers and students from the 1st, 2nd, 3rd years of the Indian Tapebas high school needed practical lessons, even if these were developed inside the classroom. This way, the idea of creating a practical manual focusing on the high school chemistry contents came up. This manual was developed through the description of the practical activities of this research with various materials used in the Indian School students’ routine. For these experimental practices, some natural and artificial materials were used, and most of them were available in the observed school. This manual is composed of 15 practices, whose aims are to improve the quality of the teaching and the learning in the theoretical classes of chemistry, through their complementation by practical lessons adequate and destined to schools that do not have a laboratory.
