What Year 8 Science students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 8 Science standard sentences this code builds towards:
- They analyse data and information to describe patterns, trends and relationships and identify anomalies.
- They analyse the key considerations that inform scientific responses and how these responses impact society.
- They select and use equipment to generate and record data with precision.
- They classify and represent different types of matter and distinguish between physical and chemical change.
- They identify assumptions and sources of error in methods and analyse conclusions and claims with reference to conflicting evidence and unanswered questions.
- They apply an understanding of the theory of plate tectonics to explain patterns of change in the geosphere.
The Science understanding progression either side of AC9S8U07
A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.
Taught before · Year 7
- AC9S7U01investigate the role of classification in ordering and organising the diversity of life on Earth and use and develop classification tools including dichotomous keys
- AC9S7U02use models, including food webs, to represent matter and energy flow in ecosystems and predict the impact of changing abiotic and biotic factors on populations
- AC9S7U03model cyclic changes in the relative positions of the Earth, sun and moon and explain how these cycles cause eclipses and influence predictable phenomena on Earth, including seasons and tides
Builds towards · Year 9
- AC9S9U01compare 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
- AC9S9U02describe 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
- AC9S9U03represent 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)
Other Year 8 Science understanding codes
- AC9S8U01recognise cells as the basic units of living things, compare plant and animal cells, and describe the functions of specialised cell structures and organelles
- AC9S8U02analyse the relationship between structure and function of cells, tissues and organs in a plant and an animal organ system and explain how these systems enable survival of the individual
- AC9S8U03investigate tectonic activity including the formation of geological features at divergent, convergent and transform plate boundaries and describe the scientific evidence for the theory of plate tectonics
- AC9S8U04describe the key processes of the rock cycle, including the timescales over which they occur, and examine how the properties of sedimentary, igneous and metamorphic rocks reflect their formation and influence their use
- AC9S8U05classify different types of energy as kinetic or potential and investigate energy transfer and transformations in simple systems
- AC9S8U06classify matter as elements, compounds or mixtures and compare different representations of these, including 2-dimensional and 3-dimensional models, symbols for elements and formulas for molecules and compounds
