Sensory play is any activity that stimulates our senses – touch, sight, hearing, smell and taste. It helps children interact with and make sense of the world that surrounds them. Messy play is the open-ended exploration of materials and their properties. Activities like squishing clay, pouring sand, and sorting stones allow children to repeat and experiment as they like. Children are naturally curious, and messy play engages their senses at a developmental level that is appropriate for them.
