S3 Biology
The aim of this year in Biology is to build on the third level Science developed in S1/2 and allow learners to attain fourth level in many Science experiences and outcomes this year.  
The third year course is intended to build an awareness of the importance of Biology in everyday life but also be sufficiently challenging to make pupils aware of the academic rigour that is needed to take the subject further.
Biology, the study of living organisms, plays a crucial role in our everyday existence, and is an increasingly important subject in the modern world. Advances in technologies have made this varied subject more exciting and relevant than ever. Biology in S3 aims to engage learners in a range of areas whilst also developing vital scientific inquiry and problem solving skills. The topics covered include cells, enzymes, genetics, reproduction and respiration.

    National 4/5 Biology
    This exciting course in Biology covers three main subject areas:

    Unit 1: Cell Biology - What happens inside the tiny cells which make up our bodies, and the all other living things, which help to keep us alive? This will include: study of cell structure and function, transport in cells, production of new cells, DNA and protein production, enzymes and their role in cells, genetic engineering, photosynthesis, and respiration.

    Unit 2: Multi-cellular Organisms - How do plants and animals control their bodies and behaviour to survive? This will include: Specialisation of cells and tissues, the role of stem cells, controlling the body (role of the brain, nerves and hormones), reproduction and inheritance, transport systems in animals (heart and blood) and plants, and effect of lifestyle on health and wellbeing.

    Unit 3: Life on Earth - How is all life on the Earth interconnected, and what are the current threats to life on earth? This will include: Factors affecting Biodiversity and distribution of life on Earth, how energy moves in the ecosystem, how nutrients (e.g. nitrogen) are recycled in the ecosystem, sampling and measuring of environmental factors, natural selection and evolution, and the human impact on the environment.

    How will the course be assessed?
    The National 4 course is internally assessed and will include a research project as part of the final assessment.
    The National 5 course is assessed by a mixture of internal assessment including an assignment and a final external exam in May.

    The Higher Human Biology course allows the learner to develop a deeper understanding of fundamental processes within the Human Body. This includes cellular processes, physiological mechanisms, communication between organisms and the biology of populations as they apply to the human species. The course takes into consideration new advances in medical research and sets it in engaging way to develop learners’ skills and knowledge.


    Human Cells (Unit 1) Through the study of human cells students gain an understanding of stem cells and their therapeutic value. This section also deals with the study of the central role of DNA in cell processes and control and regulation of metabolic pathways in cell function

    Physiology and Health (Unit 2) Helps students develop an understanding of human physiology through the study of reproduction and the cardiovascular system. The unit also looks at the significance of research in this area on the health of our nation.

    Neurobiology and communication (Unit 3) Provides students with an understanding of the basic mechanisms by which the nervous system works while giving an insight into the biological basis of psychology. The unit also looks at communication skills that allow the transmission of knowledge, development of culture and social evolution

    Immunity and Public Health (Unit 4) Familiarises students with the key components of the immune response such as recognition of pathogens and its response to them. There is also an emphasis upon applications of immunology to public health in controlling the spread of infectious disease.


    Advanced Higher Biology
    The Advanced Higher Biology Course has three mandatory Units:

    • Cells and Proteins

    • Organisms and Evolution

    • Investigative Biology

    The Course covers key aspects of life science at the molecular scale and extends to aspects of the biology of whole organisms that are among the major driving forces of evolution. Learners develop a sound theoretical understanding and practical experience of experimental investigative work in biological science.
