Didactic Basis:
In the Learning Unit Chemical phenomena in the environment, the student uses the tools for the quantification
of chemical phenomena in the environment, through their symbolic representations to evaluate their risks,
consequences and benefits in daily life. It is part of the basic training curricular structure of the UANL general
baccalaureate curriculum and belongs to the field of Experimental Sciences. The integral formation of the
student is promoted through autonomous learning, collaborative work, the use of technology in information
management, reflective, positive, critical thinking and decision-making, so that the student assumes a proactive
role. A Learning Guide is used, which includes a series of activities that will allow to develop and strengthen
the proposed competences, in addition the teacher will take care of the learning process, applying different
strategies and types of evaluation, such as diagnosis, formative and summative . It is essential that during this
course the learning achieved by the student is clearly demonstrated, this through the evaluation process. This UA
is consistent with the Learning Unit Matter and its transformations, where chemical phenomena that
manifest themselves in nature and in everyday life were approached from a qualitative approach; and is a
precedent for the UA Tópicos Selectos de Química. The purpose is to approach them from a quantitative
approach through four didactically sequenced stages: Chemical reactions and their representation; where the
different types of chemical reactions and their symbolic representation are distinguished; Aqueous solutions; in
which the properties of aqueous solutions are addressed from their composition; Acid-base solutions; where the
behavior of acids and bases based on the concentrations of hydrogen ions and hydroxide ions of the
solutions are explained; finally, Carbon Chemistry; where carbon is described as an element of organic
compounds based on their properties and chemical behavior. This Learning Unit contributes to strengthening
the basic disciplinary competencies corresponding to the field of Experimental Sciences and the generic and
general competencies that make up the profile of the graduate of the Nivel Medio Superior.
