1. Earth Resources

1. Natural resources: Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment

2. Earth and Space Systems

1. Ocean Ecosystems: Understand ocean ecosystems as interconnected systems where living things (producers, consumers, decomposers) and non-living factors (temperature, salinity, light, currents) all interact, and that changes to one part affect the whole system
2. The solar system: Describe the sun, Earth, and moon as approximately spherical bodies, and describe the movement of the Earth and other planets orbiting the sun in the solar system
3. Earth & Space Vocabulary: Use technical vocabulary for Earth's motion and the wider universe — rotation, revolution, axis, tilt, orbit, light year, gravitational force, atmosphere, lunar phases, waxing, waning, solstice, equinox, eclipse — and apply these when explaining day and night, the seasons, and the Moon's phases
4. Scale of the Solar System: Use scale models, diagrams, or calculations to represent the relative sizes and distances of objects in the solar system, understanding that the distances between planets are enormously larger than the planets themselves
5. The solar system (age 11+): Describe the detailed structure of the solar system, including moons, asteroids, and comets, compare orbital periods and distances of the planets, and distinguish between planets, dwarf planets, and other bodies
6. Weather vs climate: Obtain and combine information to describe climates in different regions of the world, distinguishing between weather and climate
7. Earth's atmosphere: Develop a model to describe ways the geosphere, biosphere, hydrosphere, and atmosphere interact as connected Earth systems
8. Using Weather Instruments: Use weather instruments to measure and record weather data: thermometers for temperature in °C, rain gauges for rainfall, wind vanes for direction, and anemometers for wind speed — and keep a weather diary over time

3. Living Systems and Processes

1. Classifying Organisms: Describe how living things are classified into broad groups (micro-organisms, plants, animals) according to common observable characteristics, similarities, and differences
2. Life Cycles of Organisms: Develop models to describe that organisms have unique and diverse life cycles but all share the common stages of birth, growth, reproduction, and death
3. Food Webs & Interdependence: Construct and interpret food webs showing the interdependence of organisms in an ecosystem, explaining how a change in one population affects others
4. Plant & Animal Reproduction: Describe the life process of reproduction in some plants and animals, including sexual and asexual reproduction in plants
5. Energy from Food & the Sun: Use models to describe that energy in animals' food was once energy from the sun, transferred through plants or other organisms
6. Structures for Survival: Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behaviour, and reproduction
