Processing, modelling and analysing

This Content Descriptor from Year 8 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 data and information to describe patterns, trends and relationships and identify anomalies

Elaborations

• identifying correlational relationships in data such as: ‘Dropping a mass from a greater height produces a larger indentation’ and analysing this relationship for causality
• describing measures of central tendency such as mean, mode and median and identifying outliers for quantitative data
• using spreadsheets to analyse second-hand data such as daily power output of solar panels and examining anomalies such as periods of reduced output
• analysing changes in battery energy output following recharging over many cycles and relating to available chemical potential energy
• comparing temperature differences obtained by reacting different proportions of the same chemicals to determine if there is a relationship

Year 8 Science Achievement Standard

By the end of Year 8 students explain the role of specialised cell structures and organelles in cellular function and analyse the relationship between structure and function at organ and body system levels. They apply an understanding of the theory of plate tectonics to explain patterns of change in the geosphere. They explain how the properties of rocks relate to their formation and influence their use. They compare different forms of energy and represent transfer and transformation of energy in simple systems. They classify and represent different types of matter and distinguish between physical and chemical change. Students analyse how different factors influence development of and lead to changes in scientific knowledge. They analyse the key considerations that inform scientific responses and how these responses impact society. They analyse the importance of science communication in shaping viewpoints, policies and regulations. Students plan and conduct safe, reproducible investigations to test relationships and explore models. They describe potential ethical issues and intercultural considerations needed for specific field locations or use of secondary data. They select and use equipment to generate and record data with precision. They select and construct appropriate representations to organise and process data and information. They analyse data and information to describe patterns, trends and relationships and identify anomalies. They identify assumptions and sources of error in methods and analyse conclusions and claims with reference to conflicting evidence and unanswered questions. They construct evidence-based arguments to support conclusions and evaluate claims. They select and use language and text features appropriately for their purpose when communicating their ideas, findings and arguments to specific audiences.
