SACE Website:  https://www.sace.sa.edu.au/web/biology

Pre-Requisite: An achievement level of ‘B’ or better in one of the subject below:

  • Stage 1 Biology A and/or Biology B
  • Stage 1 Psychology A and/or Psychology B
  • Stage 1 Chemistry
  • Stage 1 Physics


The study of Biology is constructed around inquiry into and application of understanding the diversity of life as it has evolved, the structure and function of living things, and how they interact with their own and other species and their environments.

Topics include:

  • DNA and proteins
  • cells as the basis of life
  • homeostasis
  • evolution

The topics in Stage 2 Biology provide the framework for developing integrated programs of learning through which students extend their skills, knowledge, and understanding of the three strands of science. 

The three strands of science to be integrated throughout student learning are:

  • science inquiry skills
  • science as a human endeavour
  • science understanding



The following assessment types enable students to demonstrate their learning in Stage 2 Biology:

School assessment

  • assessment type 1: investigations folio (30%)
  • assessment type 2: skills and applications tasks (40%)

External assessment

  • assessment type 3: examination (30%)

Students provide evidence of their learning through eight assessments, including the external assessment component. Students complete:

  • two practical investigations
  • one investigation with a focus on science as a human endeavour
  • four skills and applications tasks
  • one examination (external)
