Water play fosters learning in all areas of development; it's open-ended and provides opportunities for a child to learn about STEM concepts at a young age. It's the literal experience of doing, such as through water play, that supports and scaffolds young children's developing understanding of the world. As that understanding continues to grow and become more complex, they move toward more critical thinking and more creative inventing. STEM concepts grow through children's direct direct experience of the world, for example pouring water to see wheels spin. As children 'mess about' in these open-ended experiences, they have the opportunity to strengthen each area of development.Open-ended water play with cool toys allows for the experimenting with math and science concepts, strengthening physical skills, and opportunities for responsive interactions that support emotion regulation, language and relationships—that's how creative inventors and critical thinkers are nurtured.
