Abstract

Aiming at the contextualization of contents with the daily life of students as a way of providing meaningful learning, the activity of extracting DNA from fruits was developed with the objective of adapting contents and scientific practices in informal language for better understanding of students. As a methodological parameter, the Investigative Teaching Sequence was used, developed through different stages with students from the Final Years of Elementary School and High School. With the results obtained, it was possible to analyze that laboratory classes are essential during the teaching of Science and/or Biology, considering that it allows students to have direct contact with the object of study, analyzing the results and developing hypotheses in order to generate their conclusions, providing a significant improvement in the quality of learning, allowing students to exercise the ability to think, reflect and make decisions.
