Science provides an empirical way of answering interesting and important questions about the biological, physical and technological world. The knowledge it produces has proved to be a reliable basis for action in our personal, social and economic lives.



The Australian Curriculum: Science aims to ensure that students develop:

an interest in science as a means of expanding their curiosity and willingness to explore, ask questions about and speculate on the changing world in which they live.


Key ideas

In the Australian Curriculum: Science, there are six key ideas that represent key aspects of a scientific view of the world and bridge knowledge and understanding across the disciplines of science, as shown Figure 1 below. These are embedded within each year level description and guide the teaching/learning emphasis for the relevant year level.



The three interrelated strands of science
The Australian Curriculum: Science has three interrelated strands: science understanding, science as a human endeavour and science inquiry skills.

Year 6

Year 6 Level Description

The science inquiry skills and science as a human endeavour strands are described across a two-year band. In their planning, schools and teachers refer to the expectations outlined in the achievement standard and also to the content of the science understanding strand for the relevant year level to ensure that these two strands are addressed over the two-year period. The three strands of the curriculum are interrelated and their content is taught in an integrated way. The order and detail in which the content descriptions are organised into teaching and learning programs are decisions to be made by the teacher.

Incorporating the key ideas of science

Over Years 3 to 6, students develop their understanding of a range of systems operating at different time and geographic scales.

In Year 6, students explore how changes can be classified in different ways. They learn about transfer and transformations of electricity, and continue to develop an understanding of energy flows through systems. They link their experiences of electric circuits as a system at one scale to generation of electricity from a variety of sources at another scale and begin to see links between these systems. They develop a view of Earth as a dynamic system, in which changes in one aspect of the system impact on other aspects; similarly, they see that the growth and survival of living things are dependent on matter and energy flows within a larger system. Students begin to see the role of variables in measuring changes and the value of accuracy in these measurements. They learn how to look for patterns and to use these to identify and explain relationships by drawing on evidence.

Year 6 Content Descriptions

Biological sciences

The growth and survival of living things are affected by physical conditions of their environment (ACSSU094 - Scootle )
  • investigating how changing the physical conditions for plants impacts on their growth and survival such as salt water, use of fertilizers and soil types
  • observing the growth of fungi such as yeast and bread mould in different conditions
  • researching organisms that live in extreme environments such as Antarctica or a desert
  • considering the effects of physical conditions causing migration and hibernation

Chemical sciences

Changes to materials can be reversible or irreversible (ACSSU095 - Scootle )
  • describing what happens when materials are mixed
  • investigating the solubility of common materials in water
  • investigating the change in state caused by heating and cooling of a familiar substance
  • investigating irreversible changes such as rusting, burning and cooking
  • exploring how reversible changes can be used to recycle materials
  • investigate reversible reactions such as melting, freezing and evaporating

Earth and space sciences

Sudden geological changes and extreme weather events can affect Earth’s surface (ACSSU096 - Scootle )
  • investigating major geological events such as earthquakes, volcanic eruptions and tsunamis in Australia, the Asia region and throughout the world
  • recognising that earthquakes can cause tsunamis
  • describing how people measure significant geological events
  • exploring ways that scientific understanding can assist in natural disaster management to minimise both long- and short-term effects
  • considering the effect of drought on living and non-living aspects of the environment

Physical sciences

Electrical energy can be transferred and transformed in electrical circuits and can be generated from a range of sources (ACSSU097 - Scootle )
  • recognising the need for a complete circuit to allow the flow of electricity
  • investigating different electrical conductors and insulators
  • exploring the features of electrical devices such as switches and light globes
  • investigating how moving air and water can turn turbines to generate electricity
  • investigating the use of solar panels
  • considering whether an energy source is sustainable

Nature and development of science

Science involves testing predictions by gathering data and using evidence to develop explanations of events and phenomena and reflects historical and cultural contributions (ACSHE098 - Scootle )
  • investigating how knowledge about the effects of using the Earth’s resources has changed over time
  • describing how understanding of the causes and effects of major natural events has changed as new evidence has become available
  • investigating the use of electricity, including predicting the effects of changes to electric circuits
  • considering how gathering evidence helps scientists to predict the effect of major geological or climatic events
  • investigating how people from different cultures have used sustainable sources of energy, for example water and solar power
  • exploring institutions and locations where contemporary Australian scientists conduct research on catastrophic natural events
  • learning how Aboriginal and Torres Strait Islander knowledge, such as the medicinal and nutritional properties of Australian plants, is being used as part of the evidence base for scientific advances
  • investigating the development of earthquake measurements from the Chinese invention of the seismograph in the second century

Use and influence of science

Scientific knowledge is used to solve problems and inform personal and community decisions (ACSHE100 - Scootle )
  • considering how personal and community choices influence our use of sustainable sources of energy
  • investigating how understanding of catastrophic natural events helps in planning for their early detection and minimising their impact
  • recognising that science can inform choices about where people live and how they manage natural disasters
  • considering how guidelines help to ensure the safe use of electrical devices

Questioning and predicting

With guidance, pose clarifying questions and make predictions about scientific investigations (ACSIS232 - Scootle )
  • refining questions to enable scientific investigation
  • asking questions to understand the scope or nature of a problem

Year 6 Achievement Standards

By the end of Year 6, students compare and classify different types of observable changes to materials. They analyse requirements for the transfer of electricity and describe how energy can be transformed from one form to another when generating electricity. They explain how natural events cause rapid change to Earth’s surface. They describe and predict the effect of environmental changes on individual living things. Students explain how scientific knowledge helps us to solve problems and inform decisions and identify historical and cultural contributions.

Students follow procedures to develop investigable questions and design investigations into simple cause-and-effect relationships. They identify variables to be changed and measured and describe potential safety risks when planning methods. They collect, organise and interpret their data, identifying where improvements to their methods or research could improve the data. They describe and analyse relationships in data using appropriate representations and construct multimodal texts to communicate ideas, methods and findings.
