Aimed primarily at students working at level C-A* in KS4 Science, this text covers all the topics common to Double Award Science and separate Biology for five of the major examination boards: London, MEG, SEG, NEAB and WJEC. The book is divided into three main colour-coded sections: Life Processes, The Continuity of Life, and Organisms and Their Environment. The sections are further subdivided into chapters, each of which begins with a learning objectives box, outlining the main topic areas to be covered, and ends with a summary box, detailing what pupils should know having studied the chapter. Each chapter also contains a number of short homework questions and extended in-depth questions to enable pupils to gauge their level of understanding of the topic. The book places an emphasis on the importance of practical work and it includes a number of activity boxes containing recipe-style guides to practical investigations. Ideas for coursework projects are also provided. Information technology has been fully integrated within the text, both in terms of ideas for practical investigations using computers and the use of IT to carry out further research. Each major theme concludes with a number of GCSE examination questions, so that pupils become accustomed to the style.
