AC9S9I05

What Year 9 Science students should achieve

Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 9 Science standard sentences this code builds towards:

• They describe how the processes of sexual and asexual reproduction enable survival of the species.
• 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 energy conservation in simple systems and apply wave and particle models to describe energy transfer.
• They explain how interactions within and between Earth’s spheres affect the carbon cycle.
• By the end of Year 9 students explain how body systems provide a coordinated response to stimuli.

A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.

Other Year 9 Science inquiry codes

• AC9S9I01develop investigable questions, reasoned predictions and hypotheses to test relationships and develop explanatory models
• AC9S9I02plan and conduct valid, reproducible investigations to answer questions and test hypotheses, including identifying and controlling for possible sources of error and, as appropriate, developing and following risk assessments, considering ethical issues, and addressing key considerations regarding heritage sites and artefacts on Country/Place
• AC9S9I03select and use equipment to generate and record data with precision to obtain useful sample sizes and replicable data, using digital tools as appropriate
• AC9S9I04select and construct appropriate representations, including tables, graphs, descriptive statistics, models and mathematical relationships, to organise and process data and information
• AC9S9I06assess the validity and reproducibility of methods and evaluate the validity of conclusions and claims, including by identifying assumptions, conflicting evidence and areas of uncertainty
• AC9S9I07construct arguments based on analysis of a variety of evidence to support conclusions or evaluate claims, and consider any ethical issues and cultural protocols associated with accessing, using or citing secondary data or information
• AC9S9I08write and create texts to communicate ideas, findings and arguments effectively for identified purposes and audiences, including selection of appropriate content, language and text features, using digital tools as appropriate
