Even though the importance of the nature of science (NOS) and scientific inquiry in science learning have been emphasized by many science educators and science curriculums, the link between the NOS and scientific inquiry has not been discussed sufficiently. In this article, I discussed that various aspects of NOS are already embedded in defining and characterizing the authentic scientific inquiry and that we need to have special concern about how the NOS should be treated and interpreted when introducing it into scientific inquiry. And I summarized two approaches to teach the NOS and scientific inquiry; teaching the NOS through scientific inquiry and teaching scientific inquiry through the NOS. Finally, some next studies based on this article are introduced.
