A single-volume encyclopaedia that aims to make learning accessible and fun. Its eight thematic sections take young readers on a journey of exploration and learning. Beginning with the child's own body and how it works, it progresses outwards to the wider world, where people live, work and create. The horizon stretches further, to encompass the Earth with all its animals and plants, before moving on to science, technology, and finally space and the stars. Information is presented in a wide variety of ways - text, captions, child-friendly artwork, photographs, activities and fact boxes. This diversity makes the book accessible on a variety of levels, to reflect the range of interests and abilities of young children. Readers are encouraged to get involved with the text and pictures, to find out things for themselves, and to try the simple, fun experiments and projects suggested throughout.
