Written for teachers in training and classroom teachers, this book has been designed to support and extend teachers' and students' own knowledge and understanding of science and should be of particular use to non-specialists. Throughout the book every effort has been made to interpret the ideas and concepts of science in accessible language, using everyday activities as illustrations. The book consists of three sections: Life and Living Processes, Materials and their Properties, and Physical Processes. For each section Key Ideas are suggested and then expanded to include important related science concepts. The book provides comprehensive knowledge for science at key States 1 and 2, as well as setting the scene for teaching and learning at Key Stage 3.
