Processing, modelling and analysing

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 and connect a variety of data and information to identify and explain patterns, trends, relationships and anomalies

Elaborations

• discussing the validity of the data when extrapolating from a graph
• analysing representations of data from atmospheric monitoring and ice cores to identify patterns and trends in the amount of carbon dioxide in the atmosphere, highlighting inconsistencies
• comparing published data with experimental data such as the sound-insulating levels of different materials and identifying any trends or patterns in differences, such as: ‘The published sound levels are usually higher than the experimentally determined levels’
• analysing data on heat transfer through multiple layers of an insulating material and identifying patterns and proportional relationships, such as: ‘When the thickness of the material is doubled the amount of heat transferred is halved’
• examining tables, graphs and digital simulations of radioactive decay half-life to predict changes in mass over time

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.
