  Part of a series which looks at everyday products and encourages children to find out more through investigation and activities, this book examines pebbles and stones and suggests experiments and craft activities that they can be used for. Some characteristics of basic rock types - both natural and artificial - are revealed, and a recipe for home-made concrete is included.
