The construction of the chemical content in relation to the environmental dimension at the pre-university level

The Pre-university educational level is aimed at improving its teaching-learning process and has within its objectives the aspiration that students demonstrate a positive, creative and responsible attitude towards the environment, from the understanding of the interdependence of the economic dimensions, political-social and ecological of sustainable development, knowledge of the essential causes that affect it at the local, national and global levels, a fundamental condition for the maintenance and preservation of its resources and the diversity of life, as well as adaptation to climate change on the planet. In this way, in the programs of the Chemistry subject, it is proposed as an objective: to explain the cause-effect relationships in the study of the structure, properties, applications of substances, their effects on health and the environment, which encourages establish links through chemical content with environmental problems that are manifested in the different areas of the social life of students, so it is considered appropriate to develop a didactic model of treatment of chemical content in relation to the environmental dimension, which it is theoretically based, with emphasis on the construction of said content.
