AC9S9I03 Year 9 Science

This Content Descriptor from Year 9 Science provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

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

Elaborations

• 1 using an electronic balance that measures within the parameters of the required mass, and recording data to the correct number of significant figures using correct units
• 2 using data loggers and choosing correct scale and appropriate output representation
• 3 examining the degree of accuracy that different instruments provide, such as a measuring cylinder compared with a pipette, and recording data values to the correct degree of precision using appropriate scientific notation
• 4 considering the replicability of data collected using different instruments, including the inaccuracies that may be introduced when taking measurements
• 5 discussing the amount of data needed to produce a useful sample size and why sample size is important
• 6 considering an appropriate sample size for the investigation, and how the use of digital tools might enable more-efficient data collection for larger sample sizes
