Ensino de Ciências através da experimentação: a construção de um vulcão de levedura

Abstract

This investigation aims to lead students to think, debate, justify their ideas when studying the chemical processes of fermentation and catalase action, through of experimentation, in a State Public School located in the city of Santa Maria/RS. The work was developed in the laboratory of the school with a 6th grade class, during science classes and had the collaboration of the responsible teacher. The data were obtained through the application of a pre-test questionnaire with four open questions; in addition to a post-test through an open question regarding the understanding of the yeast volcano experiment. The results of the pre-test questionnaire demonstrated the need to amplify classroom discussions about basic science teaching processes based on everyday life, due the low discernment capacity of students. In contrast, during the experiment the students were curious and interested in understanding the processes that occurred in the yeast volcano. Thus, it can be seen that students learn more when exposed to different situations and the importance of experimentation in the teaching and learning process stands out, facilitating the discussion between them.

Utilização da Aprendizagem Baseada em Projetos no ensino da Biologia Celular e Molecular: relato de experiência no curso de Fisioterapia

“…Dentre estas pesquisas, descobriu-se que o corante azul de algodão com lactofenol pode ser utilizado para a coloração de fungos filamentosos, incluindo as leveduras(Almeida, Miranda & Gomes, 2018), e que as leveduras são microrganismos presentes em situações patológicas, por exemplo, mas que também são comuns no nosso dia a dia, como as leveduras encontradas no fermento biológico. Continuando a 3º etapa da ABP, descobriu-se que as leveduras encontradas no fermento biológico comum são microrganismos denominados Saccharomyces cerevisiae, e pela facilidade de obtê-las são utilizadas em vários trabalhos acadêmicos, como o exemplo demonstrado por Jora et al, (2020) na produção de um vulcão com leveduras no ensino das ciências(Joras, Bender, Candito, & Rocha, 2020).…”
