Reforms in K-12 science education and their implications for PreK teaching, make this a critical time for developing a unified vision for early childhood science education. The goal of this essay is to provide a vision of what it might look like to leverage the best of both early childhood and K-12 science education reform efforts for meaningful science learning opportunities for young children. The essay suggests to best support young children, PreK science education must implement the holistic approach of early childhood education (i.e., physical, social-emotional, and cognitive development) while at the same time taking up the richer scientific disciplinary practices put forth in recent science reform efforts. Bringing together the strengths of both early childhood and science education will support young children in making sense of natural phenomena in the world around them while valuing them as capable science learners with prior experiences.
