This updated edition addresses the examined units of the CCEA AS level Life and Health Sciences specification (including the recently-proposed revisions). It covers both the Single and Double Award courses, through the study of the following units:

• AS 2: Human Body Systems
• AS 3: Aspects of Physical Chemistry in Industrial Processes
• AS 5: Material Science

The full-colour, illustrated chapters clearly explain the theory for the course, and are supported by worked examples, tips, examination-style questions and answers.

The authors are all experienced science teachers and examiners and the book has been through a meticulous quality assurance process prior to publication.
