Biology is the study of living organisms that are investigated at four different levels over four topics:

Topic 1: DNA and Proteins – as well as understanding the structure and role of DNA and proteins, we investigate genetic modification and the ethical and social consequence of being able to obtain genetic data about ourselves and others.

Topic 2: Cells as the Basis of Life – really learning the ins and outs of cells and everything they do to sustain life.

Topic 3: Homeostasis – this topic takes a closer look at human body systems and how they work together. This topic is of particular interest for those students keen on a career related to human biology such as medicine, physiotherapy or nursing.

Topic 4: Evolution – investigates the processes of evolution and natural selection and how that leads to population changes. It also considers environmental and social issues such as global warming and other human impacts, and sustainability of populations.

There is no assumed knowledge, however, students that have studied Stage 1 Biology will find that beneficial.


School Assessment

  • Assessment Type 1: Investigations Folio (30%) – consists of several practical reports and a Science as a Human Endeavour Investigation of a contemporary topic that highlights the interaction of science with society
  • Assessment Type 2: Skills and Applications Tasks (40%) – a range of tests and assignments designed to assess your ability to apply your knowledge and understanding of the topics

External Assessment

  • Assessment Type 3: External Assessment: Examination (30%)


Biology can lead to further study in tertiary institutions in a very diverse range of fields. Students might choose to study a general degree such as a Bachelor of Science to gain further knowledge of a range of biological concepts. Other pathways may be in more specific areas of study such as medicine, agriculture, food processing, horticulture, medical laboratory science, physiotherapy and veterinary nursing.
