Cambridge International AS & A Level Marine Science Second Edition Digital Workbook (2 Years)

Explore the wonders of the underwater world and develop theoretical and practical marine science skills. Following extensive classroom research, this digital workbook has been revised by experienced teachers and examiners. The first section of the workbook includes exercises and exam-style questions for each topic to enable students to consolidate and assess their learning and apply their knowledge to novel situations. The second section includes 27 practical activities to develop students’ investigative skills. Support notes and sample data are provided in the teacher’s resource. Written in accessible language for the international learner this book helps students build confidence and develop essential skills. This Workbook is designed to support the coursebook, with specially selected topics where students would benefit from further opportunities to apply skills, such as application, analysis and evaluation in addition to developing knowledge and understanding.

(The workbook does not cover all topics in the Cambridge International AS & A Level Marine Science syllabus (9693)).
