Play is an essential part of every childâs life and is vital to their development. Through play, children explore the world around them and develop and practise skills. Childrenâs play may or may not involve equipment or have an end product. Children play on their own and with others. Their play may be boisterous and energetic or quiet and contemplative, light-hearted or very serious. Childrenâs right to play. In 1991, the UK government ratified the United Nations convention on the rights of the child. The Playday campaign is committed to achieving the full implementation of this right, to ensure all children in the UK can play.

Tin has a highly crystalline structure and when a tin bar is bent, a âtin cryâ is heard, due to the breaking of these crystals. In compounds tin is usually in the divalent state (Sn 2+) or tetravalent state (Sn 4+).It resists oxygen and water but dissolves in acids and bases.
