This paper introduces the idea of integrating indigenous knowledge (IK) in the elementary level of the K-12 Science Curriculum. The study identifies indigenous knowledge that is practiced by the people and presents instructional strategies that could be used to integrate indigenous knowledge in the science curriculum. These strategies are based on the peoples' experiences of effectively teaching indigenous knowledge to young children in their families and local communities. The results of the study could help make the elementary science curriculum more appropriate and responsive to the needs of learners in various local communities.
