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 Ãâ·ÑAƬ 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.
