Resumen

RODRIGUEZ, María Daniela et al. Biodiesel production as a model of approach to natural sciences. Educ. quím [online]. 2023, vol.34, n.3, pp.55-62.  Epub 20-Dic-2023. ISSN 0187-893X.  https://doi.org/10.22201/fq.18708404e.2023.3.84939.

Contextualizing chemistry laboratories, relating them to daily life situations and disciplinary contents, motivates to awaken scientific vocations. The objective of the work was to promote interest in exact sciences and environmental care, through the active participation of students in the reuse of vegetable oil as a laboratory model in context. The origin of vegetable oils, the health implications of the repeated reuse of vegetable oil, the possible forms of transformation into new products, transesterification, and the manipulation of chemical reagents were studied during the workshops. Recipients were high school students from 6 different institutions in the province of Misiones (Argentina), reaching a total of 45 students between 17 and 21 years old. Workshops were led by students, graduates and the directors of the project. The methodology of the activity consisted of a practical experience and evaluation of the intervention. The use of a socio-environmental context for the teaching of chemistry, generated awareness about environmental care; and new knowledge in relation to chemistry, by making use of the transesterification reaction to obtain biodiesel.
