Chemical sciences

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

compare physical and chemical changes and identify indicators of energy change in chemical reactions

Elaborations

• performing simple chemical reactions to identify the indicators of chemical change such as gas production, solid production, colour change and temperature change
• analysing and interpreting data on the properties of substances before and after the substances interact to determine if a chemical or physical change has occurred
• investigating and identifying energy changes in different chemical reactions such as differences in temperature
• examining how the physical and chemical properties of a substance will affect its production or use
• discussing where indicators of chemical change are used for identifying the presence of particular substances, such as in soil, water and medical testing kits

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.
