Colonisation: Causes and Impacts

Overview

Students investigate why Britain established colonies in Australia after 1800 and consider how colonisation affected Aboriginal and Torres Strait Islander peoples, colonists, convicts and the natural environment. They analyse short teacher-created excerpts, recognising that sources reflect particular purposes and perspectives rather than a single complete story.

Learning intentions

Students will:

• explain economic, political and social reasons for British colonisation after 1800
• describe different impacts of colonisation on people and Country
• identify the origin, purpose and perspective of a source
• use evidence to compare viewpoints respectfully

Success criteria

• I can identify at least two reasons Britain established colonies after 1800.
• I can describe an impact on First Nations Australians, convicts, colonists or the environment.
• I can identify who created a source, why it was created and whose perspective it represents.
• I can support an idea with evidence from a source.

Curriculum links

• Causes of the establishment of British colonies in Australia after 1800, including economic, political and social causes.
• Impacts of British colonies on First Nations Australians, colonists, convicts and the natural environment.
• Evaluation of primary and secondary sources for origin, purpose and perspectives.
• Aboriginal and Torres Strait Islander Histories and Cultures cross-curriculum priority.

Lesson structure (60 minutes)

1. 0–7 min · Respectful hook. Teacher opens the hook and learning intentions slides with a visual comparison of a healthy Country before and after major colonial settlement, and states: “Aboriginal and Torres Strait Islander peoples have cared for Country for tens of thousands of years. British colonisation was not the discovery of an empty land.” Students silently record what they notice and wonder, then share one question with a partner.

2. 7–17 min · Build the context. Teacher uses the timeline and causes slides to explain that Britain established or expanded colonies after 1800 for interrelated economic reasons, such as land, resources and employment; political reasons, including imperial expansion; and social reasons, including poverty, overcrowded cities and pressure on prisons. Clarify that Aboriginal and Torres Strait Islander societies were already diverse, enduring and connected to Country. Students complete a three-column cause sort on the causes and source-analysis worksheet, placing examples under economic, political or social and adding one question they still have.

3. 17–25 min · Teach source analysis. Teacher models the questions “Who created this?”, “When and where was it created?”, “Why was it created?”, “Whose perspective is included or missing?” and “What can this source tell us—and what can it not tell us?” using the first excerpt in the source-analysis model slides. Students identify one useful detail and one limitation, using the sentence frame: “This source suggests … because …”

4. 25–43 min · Collaborative source investigation. Teacher places students in five groups of five and distributes the causes and source-analysis worksheet. Each group reads four short teacher-created excerpts: a British government statement about empire and trade; a convict’s account of work and restrictions; a free settler’s account of land and opportunity; a First Nations perspective describing continuing connection to and care for Country, and the disruption caused by colonisation; and a description of environmental change, including clearing, farming and introduced animals. Students annotate each excerpt for origin, purpose, perspective, evidence and missing voices. Groups choose two excerpts that show different experiences and prepare one comparison.

5. 43–53 min · Share and synthesise. Teacher displays the discussion and impact-mapping slides and draws four headings: First Nations Australians, convicts, colonists and environment. Groups share one impact and place it under a heading, noting that one event can have different effects on different people. Students complete: “One cause of colonisation was … One impact was … This was different for … because …” Emphasise that impacts included change, hardship, opportunity for some colonists, loss and disruption for First Nations communities, and environmental transformation; experiences were not identical.

6. 53–60 min · Exit reflection. Teacher returns to the opening question using the plenary and exit-ticket slide. Students complete the final section of the causes and source-analysis worksheet: name two causes, explain one impact, and identify the perspective of one excerpt. Invite two students to share a response, reinforcing respectful language and the importance of listening for voices that may be absent.

Resources

• the complete causes, impacts and source-analysis slide deck
• the causes and source-analysis worksheet
• Teacher-created source excerpt cards or projected excerpts
• Whiteboard and markers
• Highlighters or coloured pencils
• Classroom map of Australia
• Timer
• Access to a quiet reading space or audio support

Assessment

• Check students’ cause sorting and questioning during the context activity; address confusion between economic, political and social causes.
• Listen for accurate use of origin, purpose, perspective and evidence during group analysis. Collect the worksheet to assess understanding of causes, impacts and source evaluation.
• Use the exit reflection to identify students needing further support with perspective or the distinction between a source’s evidence and its opinion.

Differentiation

• Provide a word bank, enlarged excerpts, colour-coded prompts and sentence starters: “The creator was …”, “The purpose may have been …”, “This perspective shows …” and “A missing voice might be …”
• Read excerpts aloud, offer audio recording or paired reading, and reduce the number of excerpts for students requiring literacy support. Allow drawing, oral recording or labelled notes instead of extended writing.
• Provide mixed-ability groups with roles such as reader, evidence finder, questioner, recorder and speaker. Avoid asking students to role-play dispossession or speak as First Nations people.
• Extend students by asking them to explain how two sources could both contain useful evidence while presenting different or incomplete perspectives.

Culturally responsive guidance

Use “Aboriginal and Torres Strait Islander peoples” or the specific community name when known, and use “Country” with a capital letter. Acknowledge that Aboriginal and Torres Strait Islander peoples are the continuing custodians of their lands and waters. Do not describe colonisation as peaceful settlement, discovery or occupation of empty land. Present First Nations peoples as active knowledge holders, decision-makers and resistors, not only as victims. Avoid graphic descriptions of violence; focus on evidence, consequences, survival, continuity and diverse perspectives. Where possible, consult local Aboriginal or Torres Strait Islander voices and follow community protocols when selecting additional materials.
