The Play Exchange
The Play Exchange
fostering a STEM identity

Play is foundational to learning in early childhood education. It is the cornerstone of development – a necessity.
The foundation for a lifelong love of learning is built early. By the time a child reaches age three, over 70% of their neural wiring is already complete, making the early years a critical window for impactful educational experiences. STEM learning (Science, Technology, Engineering, and Mathematics) is vital because it directly aligns with how young brains develop and absorb information.
For young children, play is not just fun; it is a critical component of healthy brain development. STEM activities harness this natural inclination, leveraging hands-on experiences to stimulate neural connections.
Join the Children’s Museum of Discovery for an afternoon of connection and collaboration as we explore how hands-on experiences and developmentally appropriate practices can be used to promote essential problem-solving, curiosity, and other STEM skills in our youngest learners.
Following the symposium: Join us for a Museum tour and happy hour highlighting our Daily Programs, Mobile Children’s Museum, and more.
