Module 4 | Ecosystem dynamics
Content 2: Past ecosystems
Lesson 1 | Evidence for past changes in ecosystems
-
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
– geological evidence
– ice core drilling
Lesson 2 | Analysing past and present technologies to provide evidence for past change
-
investigate and analyse past and present technologies that have been used to determine evidence for past changes, for example: (ACSBL005)
– radiometric dating
– gas analysis
Lesson 3 | Evidence that present day organisms have evolved from organisms in the past
-
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: (ACSBL027, ACSBL005)
– small mammals
– sclerophyll plants
Lesson 4 | Reasons for changes in past ecosystems
-
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)
