This bestselling series has been updated to ensure teachers can deliver the revised Cambridge Secondary 1 programme for science with confidence. In this new edition the material required to teach stage 7 of the science framework, covering Biology, Physics and Chemistry, is now in a single handy volume. The book has three sections, covering Biology, Physics and Chemistry, so teachers can still teach the three sciences separately if they prefer. The introductory chapter includes a new section on Scientific Enquiry, reflecting the focus of the new framework.
