Creative drama grants students not only an opportunity to display their thoughts physically, orally and written but also enables them to interpret the expressions of peers. Characteristic of learning through creative drama is the development of shared meaning through the social construction of knowledge. The primary purpose of this study is to develop seventh-grade students’ conceptual understanding of some genetic concepts, attitudes toward biology learning and awareness of forensic science. The pedagogy of creative drama consisted of determining blood types and differences in human fingerprints. Twenty students took part in this study. Data sources consisted of student journaling, classroom observations, students’ responses to attitude survey and subject evaluation forms. Students learned that within the scope of creative drama activities, how the blood group determination and the cause of people’s fingerprints were separate from each other. In everyday life, they realized how important biology is, especially in criminal work. Changes in students’ attitudes toward biology indicated a positive direction because of the extraordinary teaching method. All of the participants contribute the creative drama activity keenly. Students’ attitudes toward the pedagogy of creative drama suggest that students should be approached with this sort of learning at an early age.
