A iniciação à docência tem oportunizado aos futuros professores experiências significativas sobre o chão da escola e a complexidade da profissão docente e, junto aos estágios, tem melhorado a qualidade da formação inicial docente. Assim, neste estudo buscou-se conhecer e analisar a influência do Programa Institucional de Bolsa de Iniciação à Docência (PIBID) na formação inicial e na atuação docente de um grupo de egressos de um curso de Licenciatura em Química da região Centro-Sul do Ceará, que foram bolsistas do programa entre 2010 e 2018 e encontram-se inseridos no magistério da Educação Básica. Os dados foram gerados a partir de um questionário semiestruturado e revelam as potencialidades do programa não só para os estudantes da Licenciatura em Química, mas para todos os outros sujeitos nele envolvidos. Suas contribuições residem, dentre outros aspectos, na permanência dos estudantes na licenciatura e no seu interesse pelo magistério, influenciando na sua inserção profissional no mercado de trabalho e no desenvolvimento profissional docente deles, dos supervisores e coordenadores do programa, melhorando o ensino de Química nas escolas parceiras do subprojeto.

The discipline of chemistry is still considered difficult to understand by the students of Basic Education and this is due to the fact that they believe that this science is incomprehensible, abstract and out of their daily life and so unusable. However, this discipline is shown as a necessary science for the formation of students. Since this science studies the matter, its transformations and phenomena of nature, and is present in everyday life, it also has an indispensable role in scientific and technological development and in today's society. The objective of This work was to construct a solar distiller as an alternative to develop practical classes in the chemistry laboratory; Evaluate the efficiency of the solar distiller and the quality of distilled water and propose generating themes for various scientific subjects in high school classes. The methodology consisted of constructing the distiller, evaluating its operation for 7 days, with daily sampling of distilled water samples. From these samples, the pH, conductivity and presence of the ions chloride, carbonate, calcium and iron (II) and (III) were tested to analyze the quality of the water from the distiller, and the water supply (tap water) for comparison purposes. The Solar Distiller built with alternative materials of low cost, presented an average yield 58.7% of distilled water per day, being its viable use for laboratories of small schools that do not have a standard equipment of laboratories that Need to use distilled water to prepare solutions and other activities for practical classes. The qualitative chemical tests for the presence of ions (chlorides, carbonates and calcium) of this work were negative, but more tests would be needed to be able to certify their use for quantitative research in the scope of the research. Physicochemical Tests such as pH and conductivity were significantly better than tap water and residual condensation water from air conditioners, there is still certainty of purity suitable for use in research works. The Distiller proved very favorable for its use in practical classes of chemistry, being possible to address several subjects of the textbook.

Several everyday materials have acid-base indicator properties. This article aims to develop a reference material on acid-base indicators made from these materials, which can be used by the professor of Chemistry in the content of Acids and Bases to carry out the identification of these, and in this way, to be able to contextualize their teaching with the daily life of the students, who often associate the contents of Chemistry with something difficult to understand and without applications in everyday life. A total of 10 substances (purple grape, açaí, black olives, purple cabbage, black beans, jasmine-mango flower, minilacre flower, hibiscus flower, purple onion and eggplant) were selected for the preparation of the extracts, which were made using ethyl alcohol, found in pharmacies and markets, for a period of 24 hours. The extracts were tested on four substances: commercial muriatic acid, commercial caustic soda, vinegar and soap. All the indicators present satisfactory results, being able to identify with acid and basic substances distinction, which allows to infer that they can be used as a teaching tool by the professor of Chemistry.
