Experimentando a extração do DNA e pesquisando sobre a importância da molécula da vida com estudantes dos anos finais do Ensino Fundamental

Abstract

This study was developed with the aim of understanding the importance of experimentation in Science for studying genetic concepts, which are often considered challenging due to students' lack of prior knowledge or the complexity of the processes and terms involved. However, the use of methodologies, such as experimentation, places students at the center of the learning process, facilitating the understanding of abstract concepts and developing skills that will last throughout their lives.Thus, this research investigated the significance of extracting DNA from strawberries and kiwis to enhance the comprehension of Genetics concepts in Science classes for the final years of elementary school. The study involved the application of questionnaires before and after the experiment and conducted a qualitative analysis of the results. The data demonstrated that experimentation significantly contributed to the assimilation of genetic concepts, increased interest, and improved student performance. These findings highlight the necessity for teachers to integrate theory and practice in Science education.
