| Sumario: | This report describes the experience that was developed in the discipline of Instrumental Methods of Chemical Analysis of the 4th semester of the Superior course of Technology in Food of a public institution in the countryside of RS. Different activities were used, planned in a sequential manner, and using different strategies and didactic resources: lectures-dialogued; thematic approach; search; planning and carrying out experimental activities; article writing and oral presentation. From the subjects covered in the expository classes and the perception about the social implications of Chemistry and technologies in their lives, the students suggested the theme water for human consumption and the methods of official analysis for conducting a bibliographic research. After that, the students did the collection and physical-chemical analysis of the water samples. Then, they presented the results in the form of an article, followed by an oral presentation. It was observed that the experience motivated and aroused interest in the subjects studied in the discipline and contributed to the learning and appropriation of knowledge. It is also worth noting that, unlike previous semesters, there was no failure due to lack of frequency or grade. Individual assessments, resourcefulness in carrying out laboratory activities, mastery and knowledge demonstrated during the presentation and discussion of results confirm this finding.
