Science

A science education at Prince Alfred College will provide a boy with a well-rounded, holistic understanding of key chemical, physical and biological principles and how they are interrelated.  

Our carefully sequenced curriculum equips our boys with the requisite scientific knowledge, understandings and skills they will require to impact the ever changing  world in which they live. They will apply these learnings to systematically investigate and solve problems by making informed, evidence-based decisions related to local, national and global issues that they will encounter in the future.

Science Year 7-10 Overview

In Years 7-10 Science taught in a way which acknowledges that it is a dynamic, collaborative and creative human endeavour which makes sense of our world. Students explore biological, chemical, physical, Earth and agricultural sciences to answer important questions about the changing world. This study prepares students for the study of Physics, Chemistry or Biology at either SACE or IBDP pathways in Year 11 and 12.  

From a practical perspective, this course aims to develop an understanding of the nature of the scientific process and the ability to use a range of skills in this regard, including questioning, planning and conducting experiments and investigations based on ethical principles, collecting and analysing data, evaluating results and drawing critical, evidence-based conclusions. 

IBDP Subjects and Pathways

Science i B Update
Biology (Standard or Higher Level) - Group 4 

Course Description and Aims:
The course is divided into four broad topics; Molecules, Cells, Organisms and Ecosystems. Students will make sense of living systems through unifying these topics to develop understanding and awareness of the living world around them. This is carried further through a study of interactions at different levels of biological organization, from molecules and cells to ecosystems and the biosphere.  

The course also encompasses various experimental techniques, use of technology and mathematical processes. It includes an internal investigation, an open-ended task where students will develop a research question, gather and analyse data, draw conclusions and evaluate methodology.
