Resumo: | This work aims to contribute to the teaching and learning of Inorganic Chemistry through an investigative practice using the natural pH indicator obtained from the flowers of Plumbago auriculata (Bela Emília). The aqueous extract was tested in a range of previously known pH values, encompassing acidic, neutral, and alkaline pH. The activity was structured as a Didactic Sequence, divided into 4 moments: 1) presentation of the theme and previous discussion on acids and bases; 2) reproduction and discussion of a YouTube video on the use of acids and bases in everyday life; 3) investigative experimental part; 4) discussion and evaluation of the experiment mediated by the teacher, followed by the preparation of a final report. With the approach of the aforementioned Didactic Sequence, we hope to make the teaching of Chemistry more attractive, facilitating the guiding process of teaching and learning, and allowing the development of scientific experimentation using homemade, simple, and low-cost materials. Through this educational proposal, the teacher's approach and the involvement of the students can bring positive results, making the learning of Inorganic Chemistry (Acids and Bases) an uncomplicated and enjoyable task, as well as allowing the act of scientific experimentation in the school context, bringing Chemistry more and more into the students' daily lives. |

O extrato aquoso foi testado em uma faixa de pH previamente conhecida, abrangendo pH ácido, neutro e alcalino. A atividade foi estruturada como uma Sequência Didática, dividida em 4 momentos: 1) apresentação do tema e discussão prévia sobre ácidos e bases; 2) reprodução e discussão de um vídeo do Youtube sobre o uso de ácidos e bases no cotidiano; 3) parte experimental investigativa; 4) discussão e avaliação do experimento mediada pelo professor, seguida pela elaboração de um relatório final. Com essa abordagem da Sequência Didática mencionada, espera-se tornar o ensino de Química mais atrativo, facilitando o processo orientador do ensino e da aprendizagem, e permitindo o desenvolvimento da experimentação científica com o uso de materiais caseiros, simples e de baixo custo. Por meio dessa proposta educacional, o engajamento dos alunos e a orientação do professor podem resultar em uma aprendizagem mais efetiva em Química Inorgânica (Ácidos e Bases), tornando-a uma atividade descomplicada e prazerosa. Além disso, essa abordagem permite a realização de experimentos científicos no contexto escolar, aproximando cada vez mais a Química do dia a dia dos estudantes.Editora JRG2024-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos Paresapplication/pdfhttp://revistajrg.com/index.php/jrg/article/view/101010.55892/jrg.v7i14.1010ark:/57118/JRG.v7i14.1010JRG Journal of Academic Studies; Vol. 7 No. 14 (2024): JRG Journal of Academic Studies; e141010JRG Journal of Academic Studies ; Vol. 7 Núm. 14 (2024): Revista JRG de Estudos Acadêmicos; e141010JRG Journal of Academic Studies; V. 7 N. 14 (2024): Revista JRG de Estudos Acadêmicos; e141010Revista JRG de Estudos Acadêmicos ; v. 7 n. 14 (2024): Revista JRG de Estudos Acadêmicos; e1410102595-1661ark:/57118/jrg.v7i14reponame:Revista JRG de Estudos Acadêmicosinstname:Editora JRGinstacron:JRGporhttp://revistajrg.com/index.php/jrg/article/view/1010/877https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGonçalves, Tiago MarettiYamaguchi, Klenicy Kazumy de Lima2024-04-15T13:42:32Zoai:ojs2.revistajrg.com:article/1010Revistahttp://revistajrg.com/index.php/jrgPRIhttp://revistajrg.com/index.php/jrg/oaiprofessorjonas@gmail.com||2595-16612595-1661opendoar:2024-04-15T13:42:32Revista JRG de Estudos Acadêmicos - Editora JRGfalse |
