This write-in workbook with digital access is the perfect companion to the coursebook, giving you the opportunity to practise your essential science skills, consolidate your understanding, and apply your learning to new situations. Exercises are structured into three levels of increasing complexity: ‘focus’, ‘practice’ and ‘challenge’. They first develop your foundation skills, consolidate these skills through practice and then build your higher order thinking skills. As the book progresses, the amount of support is also reduced, helping you to become a confident, independent learner.
