interpret and use logarithmic scales  in applied contexts involving small and large quantities and change

Elaborations

• AC9M10M02_E1 - understanding that the logarithmic scale is calibrated in terms of order of magnitude; for example, doubling or powers of 10
• AC9M10M02_E2 - identifying and interpreting data representations (charts and graphs) that use logarithmic scales and discussing when it is appropriate to use this type of scale and when it is not appropriate; for example, graphs representing percentage change, a wide range of values or exponential growth
• AC9M10M02_E3 - investigating and interpreting logarithmic scales used in real-world contexts; for example, Richter, decibel and sensitivity scales or growth in investments, timescales and the spread of micro-organisms and disease and describing reasons for choosing to use a logarithmic scale rather than a linear scale
• AC9M10M02_E4 - investigating dating methods of geological sites to provide evidence of First Peoples of Australia’s human presence in Australia, including the Madjedbebe dig in the Northern Territory, that use logarithmic scales (scientific notation) and measurement accuracy in the dating

Achievement Standard Components

• ASMAT1005 - Students interpret and use logarithmic scales representing small or large quantities or change in applied contexts.
