The rest of Science inquiry in Year 9.

AC9S9I01

develop investigable questions, reasoned predictions and hypotheses to test relationships and develop explanatory models

AC9S9I03

select and use equipment to generate and record data with precision to obtain useful sample sizes and replicable data, using digital tools as appropriate

AC9S9I04

select and construct appropriate representations, including tables, graphs, descriptive statistics, models and mathematical relationships, to organise and process data and information

AC9S9I05

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

AC9S9I06

assess the validity and reproducibility of methods and evaluate the validity of conclusions and claims, including by identifying assumptions, conflicting evidence and areas of uncertainty

AC9S9I07

construct 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

AC9S9I08

write 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
