Resumo: The aim of this work was to investigate the didactic potential of an experiment about acids and bases. The experiment was developed with High School sophomores. The pedagogical intervention  reflected on how to recognize acid and alkaline products present in everyday life, the reading and discussion of a text about the origin and physical and chemical characteristics of acid and alkaline substances, carrying out an experiment using various daily life substances of acidic and basic character as well as a pH scale prepared with extract of purple cabbage and aqueous solutions of hydrochloric acid and sodium hydroxide. After the experiment, during group discussions, the students answered questions in order to analyze the observed data. Afterwards, they answered a question individually in order to verify the application of knowledge. The results demonstrated that the students had a good understanding of the knowledge developed, which leads us to conclude that research experiments, such as the one discussed here, promotes the learning of scientific knowledge.

A atividade foi desenvolvida em uma turma do segundo ano do Ensino Médio. A intervenção pedagógica envolveu reflexão sobre como reconhecer produtos ácidos e alcalinos presentes no dia a dia, a leitura e discussão de um texto sobre origem e características físicas e químicas de substâncias ácidas e alcalinas, realização do experimento utilizando várias substâncias cotidianas de caráter ácido e básico, bem como uma escala de pH preparada com extrato de repolho roxo e soluções aquosas de ácido clorídrico e hidróxido de sódio. Após o experimento, mediante discussão, os alunos, em grupos, responderam questões com vistas à análise dos dados observados. Na sequência responderam individualmente a uma questão que tinha o intuito de verificar a aplicação do conhecimento. Os resultados evidenciam que os alunos tiveram boa compreensão acerca dos conhecimentos desenvolvidos, o que nos leva a concluir que experimentos investigativos, como o discutido aqui, favorecem a aprendizagem de conhecimentos científicos. Revista Prática Docente2019-07-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionNatural SciencesCiencias NaturalesCiências Naturaisapplication/pdfhttps://periodicos.cfs.ifmt.edu.br/periodicos/index.php/rpd/article/view/55910.23926/RPD.2526-2149.2019.v4.n1.p227-241.id408Revista Prática Docente (Journal Practice Teacher); Vol. 4 No. 1 (2019): Janeiro a Junho de 2019; 227-241Revista Prática Docente (Revista Práctica Docente); Vol. 4 Núm. 1 (2019): Janeiro a Junho de 2019; 227-241Revista Prática Docente; v. 4 n. 1 (2019): Janeiro a Junho de 2019; 227-2412526-2149reponame:Revista Prática Docenteinstname:Instituto Federal de Educação, Ciência e Tecnologia de Mato Grosso (IFMT)instacron:IFMTporhttps://periodicos.cfs.ifmt.edu.br/periodicos/index.php/rpd/article/view/559/548Copyright (c) 2023 A Revista Prática Docente tem o direito de primeira publicaçãohttps://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessCavalcante Monteiro, Paula Aparecida Rodrigues, MariaSantin Filho, OuridesCorci Batista, Michel2023-06-07T00:52:26Zoai:ojs2.periodicos.cfs.ifmt.edu.br:article/559Revistahttp://periodicos.cfs.ifmt.edu.br/periodicos/index.php/rpdPUBhttps://periodicos.cfs.ifmt.edu.br/periodicos/index.php/rpd/oairevistapraticadocente@cfs.ifmt.edu.br||2526-21492526-2149opendoar:2023-06-07T00:52:26Revista Prática Docente - Instituto Federal de Educação, Ciência e Tecnologia de Mato Grosso (IFMT)false
