Use and influence of science

This Content Descriptor from Year 9 Science provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

Content Descriptor

analyse the key factors that contribute to science knowledge and practices being adopted more broadly by society

Elaborations

• researching citizen science projects related to public health and examining why people would choose to be involved
• investigating how the practices adopted by society based on research by Australian Dr Helen Mayo led to a reduction in infant mortality
• examining how assisted reproductive technologies have become widely used since their initial development
• examining how government initiatives such as Landcare support adoption of effective land restoration practices that improve soil quality and increase carbon sequestration in soils
• investigating how First Nations Australians’ fire management practices are informing and being adopted in contemporary fire management
• analysing factors that have led to the adoption of solar panels and battery storage by individuals, industries and communities
• investigating how an understanding of materials and concern for the environment have led to the adoption of widespread recycling practices

Year 9 Science Achievement Standard

By the end of Year 9 students explain how body systems provide a coordinated response to stimuli. They describe how the processes of sexual and asexual reproduction enable survival of the species. They explain how interactions within and between Earth’s spheres affect the carbon cycle. They analyse energy conservation in simple systems and apply wave and particle models to describe energy transfer. They explain observable chemical processes in terms of changes in atomic structure, atomic rearrangement and mass. Students explain the role of publication and peer review in the development of scientific knowledge and explain the relationship between science, technologies and engineering. They analyse the different ways in which science and society are interconnected. Students plan and conduct safe, reproducible investigations to test or identify relationships and models. They describe how they have addressed any ethical and intercultural considerations when generating or using primary and secondary data. They select and use equipment to generate and record replicable data with precision. They select and construct appropriate representations to organise, process and summarise data and information. They analyse and connect data and information to identify and explain patterns, trends, relationships and anomalies. They analyse the impact of assumptions and sources of error in methods and evaluate the validity of conclusions and claims. They construct logical arguments based on evidence to support conclusions and evaluate claims. They select and use content, language and text features effectively to achieve their purpose when communicating their ideas, findings and arguments to specific audiences.
