Laboratório itinerante alternativo: uma proposta de atividade interdisciplinar de biologia e química no 1° ano do ensino médio

Abstract

The objective of this work was to develop experimental activities based on proposals for interventions with an interdisciplinary approach between the contents of Chemistry and Biology, using an itinerant laboratory built with alternative materials of low cost. The activities were carried out in two classes at the José do Patrocínio State School, located in the Municipality of Macapá-AP, one control class (only theoretical class) and the other experimental class (theoretical class plus practical activity), in partnership with two teachers (one Chemistry and Biology).To subsidize the performance of interdisciplinary activities, an alternative itinerant laboratory was built and to guide the proposals for experimental classes, the experimental script was elaborated. Due to the COVID-19 pandemic, it was possible to remotely apply only the experiment, red cabbage as an acid-base indicator. The analysis of the results was carried out through the applied questionnaires. The experimental group showed a higher performance in relation to the control group, obtaining a better assimilation between theory / practice. As for the interdisciplinary activity, the students in the control class responded with indifference, a fact that can be explained by the nonperformance of the experimental activity. Regarding the teachers' perception of the importance of experimental activities, both agreed that it arouses the student's interest in the content taught in the theory. The proposal presented in this research obtained satisfactory results, since the students were able to assimilate theory more clearly and objectively in practice with an interdisciplinary approach.
