Protocolos verdes : una estrategia para la enseñanza de la química

Abstract

The school chemistry is characterized by the development of experiments, in which the color change, the precipitate, or supernatants which are evident in the test tube, called his attention, inviting the student to the description, argumentation and interpretation of the observed. However, for them is not valid limitation of reagents used, or the correct way to dispose of the nature of that reagent. This proposal arises from the need to reflect about the impact of spending indiscriminately different chemical reagents for the development of expertise and dump their waste directly on the environment once practice finished on the lab.

Reference is theoretically in green chemistry, also known as sustainable chemistry; now it considered as a new chemical worldwide trend, defined by Anastas (2006) as "the use or design techniques and chemical methods that reduce or eliminate the use or generation of waste or products harmful to the environment and human health".

The research develop under the descriptive qualitative approach using AR (Action Research) as a methodology oriented to the educational change, seeking to incorporate green chemistry into the curriculum of Natural Sciences who works at the school level with the development of methodology grooming products using "Green Protocol" or friendly practices with the environment working with eleventh grade students of the afternoon session of Rafael Uribe Uribe School located on Tunjuelito.
