Core Chemistry forms part of a three-volume resource supporting separate-science teaching for 11 to 14 year olds. It provides all the chemistry needed for pupils to do well in key stage 3 SATs or the Common Entrance Examination. The material is arranged into three topic types: Basic Concepts, Consolidation and Development. The Basic Concepts chapters provide an accessible route to understanding the key chemical concepts; each chapter begins gently and then progressively becomes more demanding. The Consolidation sections revisit the key concepts in new contexts and offer further learning and revision opportunities for all abilities. The Development topics provide further motivation and challenging material for those pupils moving on to study the separate sciences post-14.
