Introduced species are a huge problem in Australia. They can outcompete native species, and introduced predators can take advantage of prey that haven’t adapted to their presence.
In this lesson, students will cover a number of case studies analysing the ways introduced species can outcompete native species and the negative impact introduced species have had on Australian plants and animals, of which Lord Howe Island is just one example. They will then write a persuasive letter to inform and convince influential members of the community to join Lord Howe Island’s conservation efforts and continue the fight against introduced species across all of Australia.
- understand how introduced species outcompete native species
- understand how specific introduced species have negatively affected native plants and animals in Australia.
- think critically to evaluate primary and secondary sources explaining the damage caused by introduced species
- apply their knowledge through practical, real-world tasks by writing informative and persuasive texts to inspire change.

Australian Curriculum content descriptions:
Year 8 Geography:
- Human causes and effects of landscape degradation (ACHGK051)
- Ways of protecting significant landscapes (ACHGK052)
- Evaluate sources for their reliability and usefulness and select, collect and record relevant geographical data and information, using ethical protocols, from appropriate primary and secondary sources (ACHGS056)
- Present findings, arguments and ideas in a range of communication forms selected to suit a particular audience and purpose; using geographical terminology and digital technologies as appropriate (ACHGS061)
- Reflect on their learning to propose individual and collective action in response to a contemporary geographical challenge, taking account of environmental, economic and social considerations, and predict the expected outcomes of their proposal (ACHGS062)
Year 10 Science:
- The theory of evolution by natural selection explains the diversity of living things and is supported by a range of scientific evidence (ACSSU185)
- Communicate scientific ideas and information for a particular purpose, including constructing evidence-based arguments and using appropriate scientific language, conventions and representations (ACSIS208)
Cross-curriculum priority: Sustainability
Relevant parts of Year 8 Geography achievement standards:
Students explain geographical processes that influence the characteristics of places and explain how places are perceived and valued differently. They explain interconnections within environments and between people and places and explain how they change places and environments. They compare alternative strategies to a geographical challenge, taking into account environmental, economic and social factors. Students evaluate a range of primary and secondary sources to locate useful and reliable information and data. Students present findings, arguments and ideas using relevant geographical terminology and digital technologies in a range of appropriate communication forms. They propose action in response to a geographical challenge, taking account of environmental, economic and social factors, and predict the outcomes of their proposal.
Relevant parts of Year 10 Science achievement standards:
Students evaluate the evidence for scientific theories that explain the origin of the universe and the diversity of life on Earth. They explain the processes that underpin heredity and evolution. They construct evidence-based arguments and select appropriate representations and text types to communicate science ideas for specific purposes.
