This study was carried out in order to examine the potency of DNA extracts simple method in lower secondary school. Though DNA extracts have been in upper secondary school, DNA extracts have never been used in lower secondary school. Though there is no description about DNA in course of study, we think that it is important to study about DNA for lower secondary school students in aspect of scientific literacy. We conducted lessons about DNA simple extracts with Nara University of Education attached lower secondary school 3rd graders 4 classes. This method is revised not to use dangerous reagent and the centrifuge machine. The efficiency of this method was evaluated by student's attitude, experiment report and questionnaire. Most students succeeded with this experiment and they changed and improved their idea. As a result, it is clear that this DNA extracts simple method is useful for lower secondary students.
