National 4 Biology
The National 4 Biology Course covers major areas of biology including cellular, whole organism and ecosystems. The key areas of biodiversity, interdependence, body systems and cells and inheritance are developed through the Course. It enables learners to recognise the impact that biology has on society and the environment. Learners develop scientific inquiry and investigative skills, scientific analytical thinking skills and the ability to use scientific literacy in a range of contexts.

Past Papers and Marking Instructions
Added Value Unit Assessment
The Biology Added Value Unit assessment is an assignment. While describing what candidates must do, the published assessment offers considerable flexibility in the choice of a context for the assessment, in which candidates apply skills, knowledge and understanding to investigate a topical issue in biology and its impact on the environment and/or society. The issue should draw on one or more of the key areas of the Course, and should be chosen with guidance from the assessor.
Centres can access the assessment through their SQA Co-ordinator.
Information on suggested topical issues can be found in the National 4 Biology Course and Unit Support Notes. It is not mandatory to use any of the topical issues suggested. A resource pack for one possible context for this assignment is also included in the National 4 Biology Course and Unit Support Notes.
As with all SQA Unit assessments, Added Value Unit assessments must be internally verified by centres.
Unit Assessment Support
These documents contain details of Unit assessment task(s), show approaches to gathering evidence and how the evidence can be judged against the Outcomes and Assessment Standards. Teachers/lecturers can arrange access to these confidential documents through their SQA Co-ordinator.
