TURCI, Eliani Behenck Santos; PLASTER, Raquel  and  TECHIO, Kachia Hedeny. Grandma's ethnociences: composting of household organic waste in Biology and Chemistry teaching. Ensino em Re-Vista [online]. 2022, vol.29, e036.  Epub June 08, 2023. ISSN 1983-1730.  https://doi.org/10.14393/er-v29a2022-36.

This article proposes to carry out a family cultural investigation, based on ethnoscience discipline, through reports of women who are grandmothers about domestic composting. According to their narration, the practice of mixing food leftovers in the soil, animal manure and ashes from a wood stove, was a knowledge acquired since childhood, and that was passed from generation to generation. Bibliographic research was carried out to analyze the theme of composting, associating it with ethnoknowledge, based on conventional wisdom. The subject can be explored in educational environments, being a way of valuing empirical knowledge combined with science, since it involves contemporary issues such as environmental awareness and sustainability. The article also presents an alternative way to explore the topic through the interdisciplinarity between chemistry and biology, decharacterizing the current fragmented teaching of these disciplines.

Keywords : Domestic composting; Interdisciplinarity; Ethnosciences.
