Core science concepts

When exploring the natural world, the wide expanse of knowledge leads us to develop the big ideas or core concepts of science. Through the Australian curriculum, these concepts are introduced and developed in accordance with the students' age and stage.

The physical sciences involve the study of forces and motion, and matter and energy. How an object moves is influenced by a range of contact forces (friction) and non-contact forces (magnetic, gravitational, and electrostatic). Energy can come in many forms (heat, light, sound, electricity) and can be transferred between objects or transformed from one form to another.

 Forces affect the motion and behaviour of objectsEnergy can be transferred and transformed from one form to another and is conserved within systems
FDescribe how objects move and how factors including their size, shape or material influence their movementConcept not covered at this year level
Y1Describe pushes and pulls in terms of strength and direction and predict the effect of these forces on objects’ motion and shapeConcept not covered at this year level
Y2Concept not covered at this year levelExplore different actions to make sounds and how to make a variety of sounds, and recognise that sound energy causes objects to vibrate
Y3Concept not covered at this year levelIdentify sources of heat energy and examine how temperature changes when heat energy is transferred from one object to another
Y4Identify how forces can be exerted by one object on another and investigate the effect of frictional, gravitational and magnetic forces on the motion of objectsConcept not covered at this year level
Y5Concept not covered at this year levelIdentify sources of light, recognise that light travels in a straight path and describe how shadows are formed and light can be reflected and refracted
Y6Concept not covered at this year levelInvestigate the transfer and transformation of energy in electrical circuits, including the role of circuit components, insulators and conductors

 

The Earth and Space sciences involve the study of the dynamic interdependent nature of Earth’s systems and how it is part of a larger astronomical system. Interactions between Earth’s systems and astronomical systems can be explored over a range of time scales.

 Earth is part of an astronomical system; interactions between Earth and celestial bodies influence the Earth systemThe Earth system comprises dynamic and interdependent systems; interactions between these systems cause continuous change over a range of scales

Y1Concept not covered at this year levelDescribe daily and seasonal changes in the environment and explore how these changes affect everyday life
Y2Recognise Earth is a planet in the solar system and identify patterns in the changing position of the sun, moon, planets and stars in the skyConcept not covered at this year level
Y3Concept not covered at this year levelCompare the observable properties of soils, rocks and minerals and investigate why they are important Earth resources
Y4Identify sources of water and describe key processes in the water cycle, including movement of water through the sky, landscape and ocean; precipitation; evaporation; and condensationConcept not covered at this year level
Y5Concept not covered at this year levelDescribe how weathering, erosion, transportation and deposition cause slow or rapid change to Earth’s surface
Y6Describe the movement of Earth and other planets relative to the sun and model how Earth’s tilt, rotation on its axis and revolution around the sun relate to cyclic observable phenomena, including variable day and night lengthConcept not covered at this year level

 

The chemical sciences involve the study of the composition and properties of substances. This involves classifying substances, exploring physical changes (changes of state or dissolving) and how chemical changes result in the production of new substances.

 The chemical and physical properties of substances are determined by their structure at a range of scalesSubstances change and new substances are produced by rearranging atoms; these changes involve energy transfer and transformation
FRecognise that objects can be composed of different materials and describe the observable properties of those materialsConcept not covered at this year level
Y1Concept not covered at this year levelConcept not covered at this year level
Y2Concept not covered at this year levelRecognise that materials can be changed physically without changing their material composition and explore the effect of different actions on materials including bending, twisting, stretching and breaking into smaller pieces
Y3Investigate the observable properties of solids and liquids and how adding or removing heat energy leads to a change of stateInvestigate the observable properties of solids and liquids and how adding or removing heat energy leads to a change of state
Y4Examine the properties of natural and made materials including fibres, metals, glass and plastics and consider how these properties influence their useConcept not covered at this year level
Y5Explain observable properties of solids, liquids and gases by modelling the motion and arrangement of particlesConcept not covered at this year level
Y6Concept not covered at this year levelCompare reversible changes, including dissolving and changes of state, and irreversible changes, including cooking and rusting that produce new substances

 

The biological sciences involve the study of living things, their interdependence, and interaction in the environment. The ongoing process of evolution has led to a diverse range of living things that have forms and features that make them suited to their environment. This results in biological systems that are interdependent on each other and their environment.

 A diverse range of living things have evolved on earth over hundreds of millions of years; this process is ongoingBiological systems are interdependent and interact with each other and their environmentThe form and features of living things are related to the functions that their body systems perform
