Understanding Science is a series of topic-based study books for children in Key Stage 2, providing comprehensive coverage of key subject areas. Each topic contains a concise summary of the information required by the National Curriculum, together with structured practice. Each book is a stand-alone resource, so children can either work through them in order or focus on individual aspects of the subject. Together, the six books support the whole of the Key Stage 2 science curriculum, including scientific investigation, providing a solid foundation for success in science. Our Bodies meets the National Curriculum requirements for Key Stage 2 science, and covers the following areas: human life cycles, puberty, human digestive and circulatory systems, teeth, muscles, skeletons, diet, pulse rates, drugs and medicines. This book explains how to keep healthy and the changes that occur in a life cycle. It explores the variation between different animal (including human) diets, teeth and skeletons. Key features of Understanding Science include: an ‘Explanation’ to introduce each topic; activities to consolidate and revise knowledge and skills; thought-provoking facts to foster a love of learning beyond the National Curriculum; a ‘Scientific investigation’ table to identify and encourage scientific questioning opportunities across the series; a combined ‘Index and glossary’ to define key terms introduced in the text.
