Description
Summary:	The present document aims to design a didactic strategy from the Science, Technology and Society (CTS) perspective through the simulated case study model, applied to the properties and effects that mercury has on health and the environment. The strategy was developed at the Colegio Nueva Esperanza IED with tenth grade students aged between fourteen (14) and sixteen (16) years; Initially, a Likert-type questionnaire was carried out on the beliefs and conceptions that the students had about mercury, resulting in ignorance of the uses, applications and impact. The analysis of these results, in relation to the institutional study plan, gave the guideline for the design and application of the didactic strategy framed in the simulated case study model, which was organized in three sessions. In the first one, a contextualization of mercury was carried out, in the second, a fictitious story was presented in which the problem of the uses of mercury was addressed, and finally, the development of a role play about the social actors that they are part of the environmental situation produced by the use of mercury; In this way, the simulated case strategy was implemented. The classroom strategy seeks to strengthen the articulation of the contents developed in the transversal curriculum of the science area, the daily life and interests of the students, and the environmental and health problems that arise at a social level with the uses of mercury in artisanal gold mining processes. This allows students to identify the physical and chemical properties of mercury, but above all it seeks to promote through their learning an environmental awareness that integrates concepts in science.
