Full Year

In Year 9 Science, students explain chemical processes and natural radioactivity in terms of atoms and energy transfers and describe examples of important chemical reactions. They describe models of energy transfer and apply these to explain phenomena. They explain global features and events in terms of geological processes and timescales. They analyse how biological systems function and respond to external changes with reference to interdependencies, energy transfers and flows of matter. They describe social and technological factors that have influenced scientific developments and predict how future applications of science and technology may affect people’s lives.


The following topics provide the framework for learning throughout the year, but not necessarily in this order, as different Year 9 classes will cover content at different times of the year.

  • Responding to Change
  • Interdependence and Ecosystems
  • Plate Tectonics
  • Atoms
  • Changes in Matter
  • Energy Transfer
  • Energy Waves
  • Science Storytelling


Students are assessed against the Australian Curriculum Science achievement standards. Evidence of student achievement will be gathered through tests, assignments and practical reports.

Students are tested on their knowledge of plate tectonics and energy transfers. They test how changing variables affects reaction time and the amount of energy found in a range of snack foods, writing practical reports on their findings. They investigate whether nuclear energy should be used in Australia and how a bionic device of their choosing has benefited humanity. Students investigate the ecology, diversity and sustainable practices within the Port River Barker Inlet estuary. They write an article to inform the general public on a topic of their choice.
