This Course Companion follows an approach that supports the new 2007 syllabus (to be first examined in 2009) while including the wider aims of the IB through connections to TOK, international-mindedness and the IB learner profile. It has been written by a former chief examiner for IB Diploma Programme Biology and has been extensively reviewed by teachers, consultants and the IB. With features and activities that encourage active learning and critical thinking, students will find this book stimulating and engaging.

• 'Data Based Questions' and 'Rediscovering Biology' features help students think critically about science and consider its evolution
• Includes coverage of the core and AHL as well as selective coverage of the Options with examination questions throughout
• A separate chapter is devoted to Extended Essays in Biology
• Highly illustrated with descriptions of laboratory practicals for the Internal Assessment
• 'Thinking About Science' is a thought-provoking feature with interesting extracts that make connections to real world issues and events
