AC9S9I05 Year 9 Science

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

Elaborations

• • Elaboration discussing the validity of the data when extrapolating from a graph
• • Elaboration analysing representations of data from atmospheric monitoring and ice cores to identify patterns and trends in the amount of carbon dioxide in the atmosphere, highlighting inconsistencies
• • Elaboration comparing published data with experimental data such as the sound-insulating levels of different materials and identifying any trends or patterns in differences, such as: ‘The published sound levels are usually higher than the experimentally determined levels’
• • Elaboration analysing data on heat transfer through multiple layers of an insulating material and identifying patterns and proportional relationships, such as: ‘When the thickness of the material is doubled the amount of heat transferred is halved’
• • Elaboration examining tables, graphs and digital simulations of radioactive decay half-life to predict changes in mass over time
