Step-by-Step Science provides a simple introduction to a wide range of scientific subjects. Each topic is explained with examples from everyday life, and through the use of activities and simple experiments makes science both fun and accessible. All the Step-by-Step titles are written in a direct and easy style. They are illustrated in full colour with a lively mix of artwork and photographs. Each title follows the Step-by-Step approach, gradually building up for children a wider picture of the world in which they live.
