Curriculum Codes

AC9S2H01 9

Describe how people use science in their daily lives, including using patterns to make scientific predictions

AC9S6H01 9

Examine why advances in science are often the result of collaboration or build on the work of others

AC9S2I01 9

Pose questions to explore observed simple patterns and relationships and make predictions based on experiences

AC9S2I02 9

Suggest and follow safe procedures to investigate questions and test predictions

AC9S5I04 9

Construct and use appropriate representations, including tables, graphs and visual or physical models, to organise and process data and information and describe patterns, trends and relationships

AC9S2I05 9

Compare observations with predictions and others’ observations, consider if investigations are fair and identify further questions with guidance

AC9S5I03 9

Use equipment to observe, measure and record data with reasonable precision, using digital tools as appropriate

AC9S5U04 9

Explain observable properties of solids, liquids and gases by modelling the motion and arrangement of particles
