The purpose of the National 5 biology course is to develop learners’ interest and enthusiasm for biology in a range of contexts. The skills of scientific inquiry and investigation are developed, throughout the Course, by investigating the applications of biology. This will enable learners to become scientifically literate citizens, able to review the science-based claims they will meet.
The course consists of three taught units, an externally-marked assignment and a final exam.
Unit 1 – Cell Biology
This unit involves the study of:
- Cell structure
- Transport across cell membranes
- DNA and the production of proteins
- Proteins
- Genetic engineering
- Respiration
Unit 2 – Multicellular Organisms
This unit involves the study of:
- Producing new cells
- Control and communication – nervous control and hormonal control
- Reproduction
- Variation and inheritance
- Transport systems – plants and animals
- Absorptions of materials
Unit 3 – Life on Earth
This unit involves the study of:
- Ecosystems
- Distribution of organisms
- Photosynthesis
- Energy in ecosystems
- Food production
- Evolution of species
Assessment
This is worth 20 marks out of the total of 120 marks for this course.
The assignment has two stages:
- research
- report
The assignment report will be externally marked by SQA
Exam
This consists of a 2 hour 30 minutes written paper in two sections:
1) Multiple choice – 25 marks
2) Short answer questions – 75 marks
This paper will be marked externally by SQA and will contribute to 80% of the final grade.
Progression
- Higher biology
- Entry to employment, training and further education.
