Abstract

This article aims to make a critical discussion focused on the role of an experimental activity in the discipline of biology taught at High School level. It addresses the possible errors inherited in this activity that might be transferred to the students’scientific knowledge construction. This inquiry was done at a public school located in the city of Dourados, Mato Grosso do Sul, Brasil. The reports produced by students at High School were analyzed
after an experimental activity. Data were analyzed according to Gaston Bachelard’s theory. We conclude that the experimental activities can encourage students to obtain empirical understandings related to their knowledge construction.
