This study aims to formulate an Early Childhood Education (PAUD) curriculum design based on the integration-interconnection model, incorporating the instilling of Tawhid values through basic science learning. The study is motivated by the persistent dichotomy between science instruction and religious education in early childhood settings, which prevents children from interpreting natural phenomena as signs of the greatness of Allah SWT. A descriptive qualitative approach utilizing a literature review method was employed. Data were gathered from 26 sources including journals, books, and relevant educational documents published between 2020 and 2025and analyzed through processes of identification, classification, interpretation, and synthesis. The study's primary contribution lies in the formulation of an applicable curriculum framework that concretely bridges hands-on empirical science activities with abstract spiritual understanding for young children an operational approach largely unexplored in previous research, which has generally focused on theoretical integration at a macro level. The findings demonstrate that the integration-interconnection concept can holistically link basic science with Islamic values through methods of observation, exploration, and simple experimentation. Consequently, this curriculum offers an effective solution for balancing intellectual intelligence, spiritual growth, and Islamic character development from an early age.
