Changing Landscapes: Colonial Impact

Active learning works because this topic asks students to see landscapes as living systems shaped by human decisions. Hands-on mapping, role-plays, and model building let students move from abstract ideas to concrete comparisons between two very different ways of caring for country.

Learning Objectives

1. Compare traditional First Nations land management practices with early European land use methods.
2. Analyze the immediate environmental impacts of colonial agriculture and settlement on the Australian landscape.
3. Explain how specific European farming techniques altered soil and water systems.
4. Evaluate the long-term ecological consequences of early colonial land clearing and introduced species.
5. Identify key differences in biodiversity management between First Nations peoples and European settlers.

Concept Mapping

⏱ 45 min·Pairs

Mapping Activity: Before and After Settlement

Provide historical and modern maps of a local area. In pairs, students annotate differences in vegetation, watercourses, and land use, then discuss First Nations practices from provided sources. Share findings on a class mural.

Prepare & details

Compare European land use practices with traditional First Nations land management.

Facilitation Tip: During Mapping Activity, ask students to use two colors: one for colonial clearing and one for First Nations fire mosaics, so the contrast becomes visually immediate.

Setup: Tables with large paper, or wall space

⏱ 50 min·Small Groups

Role-Play Simulation: Land Management Debate

Divide class into groups representing European settlers and First Nations custodians. Each prepares arguments for their methods using evidence cards, then debates impacts on a shared landscape model. Vote on sustainable choices.

Prepare & details

Analyze the initial environmental changes brought by colonial agriculture and settlement.

Facilitation Tip: In the Role-Play Simulation, assign roles that force perspective-taking: a settler wanting quick profit, an Elder protecting cultural sites, and a scientist measuring soil loss.

Model Building: Landscape Change Diorama

Students in small groups construct dioramas showing pre- and post-settlement landscapes with materials like clay, sticks, and fabric. Label changes and First Nations techniques, then present predictions of future states.

Prepare & details

Predict the long-term ecological consequences of these early changes.

Facilitation Tip: For Model Building, provide a base map with marked waterways and supply miniatures for sheep, eucalyptus trees, and traditional digging sticks to make changes tangible.

⏱ 30 min·Whole Class

Inquiry Walk: Local Evidence Hunt

Lead a schoolyard or nearby walk to observe signs of landscape change like introduced plants. Students photograph and journal evidence, comparing to First Nations management in class discussion.

Prepare & details

Compare European land use practices with traditional First Nations land management.

Facilitation Tip: On the Inquiry Walk, give each pair a simple checklist of colonial-era features (fence lines, old dams) and Indigenous features (scarred trees, native grass patches) to locate and photograph.

Teaching This Topic

Approach this topic as a balance between acknowledging colonial disruption and honoring Indigenous knowledge systems. Use the activities to build empathy first, then guide students to judge actions by their ecological outcomes rather than intentions. Avoid framing this as a simple ‘good vs bad’ story; instead, focus on systems thinking so students see how practices connect to biodiversity and water health over time.

What to Expect

Successful learning shows in students’ ability to explain at least three colonial impacts on landscapes and identify two First Nations practices that maintained healthy ecosystems. They should use evidence from their activities to support comparisons and share clear concerns about ongoing effects.

Watch Out for These Misconceptions

Common Misconception

During Mapping Activity, watch for students labeling the pre-1788 map as ‘empty’ or ‘wilderness.’

What to Teach Instead

Prompt students to annotate the map with evidence of Indigenous stewardship, such as ‘cool burns here,’ ‘hunting trails marked by scarred trees,’ and ‘seasonal campsites near water.’

Common Misconception

During Role-Play Simulation, listen for students assuming settler farming was always beneficial.

What to Teach Instead

Have students track the ‘ecological cost’ on a shared board during the debate, such as soil loss or weed spread, to make unintended consequences visible.

Common Misconception

During Model Building, watch for students creating dioramas that show Indigenous landscapes as unchanged.

What to Teach Instead

Require students to include at least one sign of active management, like a fire mosaic drawn in colored sand or a small dam made of sticks, to highlight purposeful care.

Assessment Ideas

Discussion Prompt

After Mapping Activity, have students pair up and respond to the prompt: ‘Imagine you are a First Nations Elder and a new European settler in 1850. What would you observe about their farming methods, and what concerns might you have for the land?’ Listen for references to soil, water, and biodiversity in their shared reflections.

Quick Check

During Model Building, review completed dioramas and captions to check that students have correctly identified at least one colonial impact (erosion, weed invasion) and one Indigenous practice (cool burns, selective harvesting) in their models.

Exit Ticket

After the Inquiry Walk, ask students to write one sentence describing a specific environmental change they observed and one sentence explaining how a First Nations practice could have prevented it.

Extensions & Scaffolding

• Challenge students to design a hybrid land management plan that combines the best practices from both systems and present it to the class.
• Scaffolding: Provide sentence starters on cards, such as ‘First Nations burning kept the land healthy by…’ to support students who need help articulating Indigenous practices.
• Deeper exploration: Invite a local Aboriginal ranger or Elder to share their fire management practices and compare them to the class findings from the diorama activity.

Key Vocabulary

Land management	The way people use and care for the land, including practices for farming, conservation, and resource use.
Cool burns	A traditional First Nations practice of controlled, low-intensity fires used to clear undergrowth, promote new growth, and manage ecosystems.
Pastoralism	The practice of raising large numbers of animals, such as sheep and cattle, on vast areas of land, often leading to significant land clearing.
Soil erosion	The process where the top layer of soil is worn away by natural forces like wind and water, often accelerated by human activities like clearing land.
Introduced species	Plants or animals that have been brought to a new environment by human activity, which can sometimes outcompete native species.
