analyse palaeontological and geological evidence that can be used to provide evidence for past changes in ecosystems, including but not limited to:

• Aboriginal rock paintings

• rock structure and formation

• ice core drilling

TEXT

investigate and analyse past and present technologies that have been used to determine evidence for past changes, for example: (ACSBL005)

• radiometric dating

• gas analysis

text

analyse evidence that present-day organisms have evolved from organisms in the past by examining and interpreting a range of secondary sources to evaluate processes, claims and conclusions relating to the evolution of organisms in Australia, for example: (ACSBL005, ACSBL027)

• small mammals

• sclerophyll plants

investigate the reasons for changes in past ecosystems, by:

• interpreting a range of secondary sources to develop an understanding of the changes in biotic and abiotic factors over short and long periods of time (ACSBL025, ACSBL026)

• evaluating hypotheses that account for identified trends (ACSBL001)
