Subject Description

By the end of Year 8, students compare physical and chemical changes and use the particle model to explain and predict the properties and behaviours of substances. They identify different forms of energy and describe how energy transfers and transformations cause change in simple systems. They compare processes of rock formation, including the time scales involved. They analyse the relationship between structure and function at cell, organ and body system levels. Students examine the different science knowledge used in occupations. They explain how evidence has led to an improved understanding of a scientific idea and describe situations in which scientists collaborated to generate solutions to contemporary problems.Students identify and construct questions and problems that they can investigate scientifically. They consider safety and ethics when planning investigations, including designing field or experimental methods. They identify variables to be changed, measured and controlled. Students construct representations of their data to reveal and analyse patterns and trends, and use these when justifying their conclusions. They explain how modifications to methods could improve the quality of their data and apply their own scientific knowledge and investigation findings to evaluate claims made by others. They use appropriate language and representations to communicate science ideas, methods and findings in a range of text types.

Science Understanding

Students look at the fact that cells are the basic units of living things and have specialised structures and functions and that multi-cellular organisms contain systems of organs that carry out specialised functions that enable them to survive and reproduce. They investigate that the properties of the different states of matter can be explained in terms of the motion and arrangement of particles, that differences between elements, compounds and mixtures can be described at a particle level and that chemical change involves substances reacting to form new substances. Students discuss that sedimentary, igneous and metamorphic rocks contain minerals and are formed by processes that occur within Earth over a variety of timescales. They investigate that energy appears in different forms including movement (kinetic energy), heat and potential energy, and causes change within systems.

Science as a Human Endeavour

This is developed over a two year period during Years 7 and 8. Scientific knowledge changes as new evidence becomes available, and some scientific discoveries have significantly changed people’s understanding of the world. Science knowledge can develop through collaboration and connecting ideas across the disciplines of science. Science and technology contribute to finding solutions to a range of contemporary issues; these solutions may impact on other areas of society and involve ethical considerations. Science understanding influences the development of practices in areas of human activity such as industry, agriculture and marine and terrestrial resource management. People use understanding and skills from across the disciplines of science in their occupations.

Science Inquiry Skills

This is developed over a two year period during Years 7 and 8. Students identify questions and problems that can be investigated scientifically and make predictions based on scientific knowledge. They collaboratively and individually plan and conduct a range of investigation types and in fair tests, measure and control variables. They use a range of techniques, including tables, graphs, keys and models to represent and analyse patterns or relationships. Students summarise data and use scientific understanding to identify relationships and draw conclusions.  They reflect on the method used and identify improvements to it as well as using scientific knowledge and findings from investigations to evaluate claims. Students communicate ideas, findings and solutions to problems using scientific language and representations using digital technologies as appropriate.
