Coverage of the Australian Curriculum

The online courses are aligned with Version 9.0 of the Australian Curriculum.

Year 9 Chemistry – Science Understanding

• Explain how the model of the atom changed following the discovery of electrons, protons and neutrons and describe how natural radioactive decay results in stable atoms (AC9S9U06).
• Model the rearrangement of atoms in chemical reactions using a range of representations, including word and simple balanced chemical equations, and use these to demonstrate the law of conservation of mass (AC9S9U07).

Year 9 Biology – Science Understanding

• Compare the role of body systems in regulating and coordinating the body’s response to a stimulus, and describe the operation of a negative feedback mechanism (AC9S9U01).
• Describe the form and function of reproductive cells and organs in animals and plants, and analyse how the processes of sexual and asexual reproduction enable survival of the species (AC9S9U02).

Year 9 Physics – Science Understanding

• Use wave and particle models to describe energy transfer through different mediums and examine the usefulness of each model for explaining phenomena (AC9S9U04).
• Apply the law of conservation of energy to analyse system efficiency in terms of energy inputs, outputs, transfers and transformations (AC9S9U05).

Year 9 Earth & Space – Science Understanding

• Represent the carbon cycle and examine how key processes including combustion, photosynthesis and respiration rely on interactions between Earth’s spheres (the geosphere, biosphere, hydrosphere and atmosphere) (AC9S9U03).

 

Subscription Information

Class subscriptions last for one year from the date of student enrolment (not from the date of purchase). This means that subscriptions can be purchased the preceding year.

Subscriptions do not auto-renew.
