Application of the concept of hormesis in the teaching of the chemistry of transition metals
Keywords:
teaching, chemistry, hormesis, bioelements, prior knowledgeAbstract
The aim of this work is to approach the study of the chemistry of transition metals, and more specifically of iron and copper, associating the concept of hormesis with previous knowledge of physics, chemistry and experimental results of the teacher-researchers. In the theoretical approach to transition metals, bibliographic data and research results of teachers are included, and relationships are established with dose and concentration of solutions calculus, interpretation of graphs, tables and figures. Likewise, the analysis of the participation of these metals as catalysts of reactions of reactive oxygen species formation is added and their toxic effects are discussed. This strategy brings students closer to scientific research, increases their interest, attention and participation in class, and strengthens the incorporation of content related to transition metals.
