What is a common material used in children's play areas?

Sand is a common material used in children's play areas primarily due to its soft texture and cushioning properties, which help prevent injuries from falls. It is easy to dig and mold, allowing children to engage in creative play activities such as building sandcastles or digging. Additionally, sand provides a stimulating sensory experience for young children, which is important for their development.

Another reason for using sand is its drainage capability, which helps prevent water pooling on the surface. This is particularly beneficial in outdoor environments, as it keeps the play area safe and usable even in wet conditions. Moreover, sand is widely accessible and cost-effective, making it a practical choice for playgrounds in various settings, including schools, parks, and backyards.

While the other materials listed—rubber, asphalt, and gravel—each have their own merits in different contexts, sand remains popular specifically for its playful characteristics and safety features that cater to the needs of children in play areas.
