Abstract: The results obtained in the implementation of a contextualization strategy in which 105 sixth-semester high school students belonging to five groups are presented, addressing the content The study of polymers and their impact currently on the world. This topic corresponds to the second unit of the Chemistry IV course of the College of Sciences and Humanities, which is High School level. It was applied in the penultimate week of classes by addressing learning: It argues the need to make responsible use of synthetic polymeric materials, by digging into documentary sources their identification and recycling methods. A printed initial questionnaire was conducted to know the depth of the knowledge acquired during the course which was developed through a contextualization strategy in which 5 short videos were observed and discussed. After the strategy was reassessed with another questionnaire answered in a Google Drive form, the results indicate that teaching polymers framed in the recycling topic had a positive impact in the learning process.
