Evaluate the engineering and human challenges of long-duration spaceflight to Mars — radiation exposure, muscle and bone loss, psychological isolation…

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 // The Human Body

Explain that cancer occurs when mutations in DNA disable normal cell-cycle controls, causing uncontrolled cell division and tumour formation; describe how stem…

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

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

Explain that white light is a mixture of all visible colours (ROYGBIV), describe dispersion through a prism, explain why objects appear coloured (selective…

Science // Waves, Light & Sound

Describe waves in terms of amplitude, wavelength, frequency, and wave speed; distinguish transverse waves (oscillation perpendicular to direction of travel)…

Science // Waves, Light & Sound

Explain that sound is produced by vibrating objects and travels as a longitudinal pressure wave through solids, liquids, and gases; describe reflection of sound…

Science // Waves, Light & Sound

Describe the full electromagnetic spectrum from radio waves to gamma rays, in order of increasing frequency and energy; explain that all EM waves travel at the…

Science // Waves, Light & Sound

Explain how waves can be absorbed, transmitted, or reflected by different materials, and apply these interactions to explain colour perception, sight…

Science // Waves, Light & Sound

Construct ray diagrams to show the formation of images by plane mirrors and converging lenses, identifying whether images are real or virtual, magnified or…
