Developed in cooperation with the IB and created by experienced IB authors, examiners and teachers, this Course Book is fully aligned to the 2023 subject guide for DP Chemistry, providing comprehensive and engaging coverage of all topics. The book nicely uses images to help to break up the text, and the images are relevant to the real world, which helps when teaching through a lens or a context. There are also plenty of other real-world applications with regard to the syllabus context and this will help students and teachers to see things through a particular lens, enhancing their learning experience. The content follows the road map given in the guide but the structure and reactivity sections are nicely broken up using the skills section. This ties together both strands of the course seamlessly. I think the book will be very useful in helping students understand the conceptual nature of the course, as well as providing teachers with an extremely useful resource to enhance their teaching. The Scientific Investigation section is well written and easy to understand and follow with plenty of useful examples.
