The resource takes students on a successful learning journey with clear learning objectives, end-of-chapter checklists and reflection opportunities. Engaging activities develop their essential science skills, thinking skills and life skills. Students have plenty of opportunities to prepare for examination with numerous exam-style questions and exam tips, while formative assessment throughout supports them as they learn. Answers and a wealth of exam-style questions are available via Cambridge Go.
