Abstract

This work is born of the concern about the way Biochemistry has been treated, among the contents of Chemistry in High School. The purpose of this work was to elaborate and evaluate a didactic sequence that would allow to contextualize the teaching of Biochemistry, when using the topic of Carbohydrates. The methodological path was drawn from a qualitative approach. The didactic sequence was applied in the third year of high school of a public school, in the municipality of Bagé-RS.
