Experimental biology workshops: an experience in university extension at a school in the semiarid of bahia

The scientific knowledge is subjected to a process of production whose dynamics involves transformations in the understanding of the treatment of nature, which impedes from being characterized as ready, true and finished. Moreover, this is a challenge in the field of scientific education. In this sense, it is one of the functions of Science teaching to enable the student to appropriate the structure of scientific knowledge and its explanatory and transformative potential. For this, we use an inherent strategy of Biology teaching - "experimentation", an important piece in the evolution of Sciences, as well as becoming part of a process which shelters concept and scheme networks which are interrelated. In this article, we present the experience report from the use of this methodology as a tool to assimilate Biology concepts for students of the 12th grade of high school, in a public school. The results point out that the teaching of Biology through research is in need of a change in the epistemological, cognitive and motivational conception on the importance of this tool.
