LEVEL: Stage 1
SACE Credits: 10 credits per semester
LENGTH: 1 semester
Students can choose to do one or both semesters.
Recommended background:
Successful completion of Year 10 Science. Biology A is not a prerequisite for Biology B.
Content:
In Stage 1 students learn about the structure and function of cells and microorganisms and how microorganisms may cause disease but also have a significant role in industry and the environment. They have the opportunity to engage with the work of biologists and to join and initiate debates about how biology impacts on their lives, society, and the environment.
Students design, conduct, gather, and analyse evidence in biological investigations.
As they explore the interaction between science and society, students recognise that the body of biological knowledge is constantly changing and increasing through the application of new ideas and technologies.
The topics for Stage 1 Biology A are:
Cells and Microorganisms (Biology A):
In this topic, students examine the development of the cell theory, the exchange of materials, and processes required for cell survival. Students use the microscope and digital modelling to study the structure and function of cells, and investigate ways in which matter is recycled and energy is transformed and transferred in the biochemical processes of photosynthesis and respiration.
Many unicellular microorganisms cause disease in human beings, and others are used in science and industry. Students learn about the conditions necessary for the growth and survival of microorganisms, their role in decomposition and food spoilage, and innovative uses of microorganisms.
Biodiversity and Ecosystem Dynamics (Biology A):
In this topic, students investigate diverse ecosystems, exploring the range of biotic and abiotic components to understand the dynamics, diversity, and underlying unity of these systems.
Students develop an understanding of the processes involved in the movement of energy and matter in ecosystems. They investigate ecosystem dynamics, including interactions within and between species, and interactions between abiotic and biotic components of ecosystems. They also investigate how measurements of abiotic factors, population numbers and species diversity, and descriptions of species interactions, can form the basis of meaningful comparisons between ecosystems. Students use classification keys to identify organisms, describe the biodiversity in ecosystems, and investigate patterns and changes in relationships between species.
Assessment:
Students’ performance will be determined according to the SACE Performance Standards. Grades A to E will be used for reporting purposes.
For a 10-credit subject, students undertake four assessment tasks including:
At least one practical investigation (i.e. experiment and report)
One investigation with a focus on science as a human endeavour, and
At least one skills and applications task (i.e. test or similar assessment item).
