AQA AS/A2 Biology Student Unit Guide New Edition: Units 3 & 6 Investigative and Practical Skills in Biology

Student Unit Guides are perfect for revision. Each guide is written by an examiner and explains the unit requirements and summarises the relevant unit content. The Introduction includes advice on how to use the guide, an outline of 'How Science Works', terms used in the Unit 3 and Unit 6 assessments, and an overview of 'The Process of Science', including the scientific method, independent and dependent variables, and precision, reliability and validity of results. The Content Guidance provides an examiner's overview of the key skills required by the unit, specific investigations you need to know about and other skills you will need. It is designed to help make students aware of the concepts they need to understand and the types of tasks they might meet in the assessment.
