Explain how pathogens (bacteria, viruses, and fungi) cause disease and describe how the immune system responds, including the roles of white blood cells…

Science // Organisms & Life Processes

Explain the effects of recreational drugs including alcohol, tobacco, and illegal substances on behaviour, health, and body systems, and distinguish between…

Science // Scientific Inquiry

Distinguish between precision (consistency of repeated readings) and accuracy (closeness to true value), use significant figures and standard form correctly…

Science // Space Exploration

Describe how astronomers detect planets around other stars using transit photometry (dip in starlight as a planet crosses) and radial velocity (Doppler wobble…

Science // Space Exploration

Explain how the electromagnetic spectrum is the primary tool of modern astronomy — different wavelengths (radio, infrared, visible, ultraviolet, X-ray…

Science // Space Exploration

Apply Newton's laws to explain orbital motion: why orbit is continuously falling sideways rather than floating; how a gravity assist (slingshot manoeuvre)…

Science // Space Exploration

Explain stellar nucleosynthesis: the Big Bang produced mainly hydrogen and helium; main-sequence fusion builds elements up to iron; and supernovae produce…

Science // Space Systems & Earth's History

Explain that the seasons are caused by the tilt of Earth's axis during its orbit around the Sun, distinguishing this from the common misconception that seasons…

Science // Space Systems & Earth's History

Explain the phases of the Moon as the changing angle of sunlight on the lunar surface as seen from Earth, and describe how solar and lunar eclipses occur

Science // Space Systems & Earth's History

Describe the detailed structure of the solar system, including moons, asteroids, and comets, compare orbital periods and distances of the planets, and…

Science // Space Systems & Earth's History

Describe the scale of the universe, including the structure of galaxies, the position of the Sun in the Milky Way, and the use of light years as a unit of…

Science // Space Systems & Earth's History

Describe gravity as a universal attractive force between all masses, explain that orbital motion arises because gravity provides the centripetal force keeping…

Science // Space Systems & Earth's History

Describe the life cycle of a star from nebula through main sequence to its end state (white dwarf, neutron star, or black hole depending on mass), and relate…

Science // The Human Body

Explain how neurons transmit signals as electrochemical impulses across synapses, describe how the brain is organised (lobes and functions, limbic system for…

Science // The Human Body

Distinguish innate (non-specific, immediate) from adaptive (specific, memory-forming) immunity; explain how B cells produce antibodies that recognise specific…

Science // The Human Body

Explain homeostasis as the process of maintaining a stable internal environment; describe the main feedback loop systems (negative feedback) using blood glucose…

Science // The Human Body

Describe the double helix structure of DNA (base pairs, complementarity), explain how genes are sections of DNA that code for proteins, introduce the central…

Science // Volcanoes & Earthquakes

Understand that convection currents in the molten mantle drive the movement of rigid tectonic plates; distinguish between convergent (collision/subduction)…

Science // Volcanoes & Earthquakes

Distinguish between P-waves (compression, travel through solids and liquids) and S-waves (shear, cannot pass through liquids); explain why a seismic shadow zone…

Science // Volcanoes & Earthquakes

Describe calderas such as Yellowstone and Toba as supervolcanoes capable of erupting thousands of cubic kilometres of ash; explain how sulphur dioxide aerosols…

Science // Volcanoes & Earthquakes

Explain probabilistic hazard assessment using eruption recurrence intervals and fault slip rates; describe how volcano observatories monitor ground deformation…

Science // Volcanoes & Earthquakes

Explain how large igneous provinces (LIPs) — massive outpourings of lava over millions of years — caused global warming and ocean acidification that drove mass…

Science // Waves, Light & Sound

State the law of reflection (angle of incidence = angle of reflection) and explain refraction as the change in speed and direction when light crosses a boundary…

Science // Waves, Light & Sound
