This paper offers a comparative reflection on how two nations, the U.S. and Lithuania, are implementing inquiry-based science in elementary classrooms. The qualitative study explored how fourth grade teachers in Southern California and in Lithuania employed effective inquiry-based strategies in their classrooms. A teacher's use of questioning strategies to guide critical thinking and the role of inquiry-based pedagogy plays in promoting student engagement were commonalities in both countries. "Exercise moments", resource conservation, and "voyeuristic investigations" were noted in Lithuanian inquiry practices while pacing guides and standards coverage were prevalent issues in US inquiry practices.
