Mitigating Human Impact

Active learning helps students see how soil erosion and land degradation respond to real strategies, building confidence in human impact solutions. Hands-on tasks like modeling and mapping connect abstract concepts to visible, measurable changes in soil and plant health.

Activity 01

Project-Based Learning45 min · Small Groups

Model Building: Terracing Erosion Prevention

Provide trays with sloped sand layers. Students build mini-terraces using cardboard and test water flow with and without vegetation (moss or grass seeds). Groups measure and compare soil loss, then discuss results. Record findings in sketches.

Explain how terracing and vegetation cover can reduce soil erosion on sloped and degraded land.

Facilitation TipDuring Model Building: Terracing Erosion Prevention, have students test different slope angles with and without terraces to observe soil retention differences.

What to look forProvide students with images of different degraded landscapes (e.g., a steep, bare hillside; a sandy coastal area). Ask them to write two sentences for each image explaining a specific strategy (scientific or Indigenous) that could help restore it.

Simulation Game50 min · Pairs

Simulation Game: Cultural Burning Effects

Use safe models with dry grass, matches under supervision, and fire-retardant trays to simulate controlled burns. Students observe regrowth with planted seeds versus unburnt areas over days. Compare to video examples of traditional practices and note biodiversity changes.

How have Aboriginal and Torres Strait Islander peoples used traditional land management practices, such as cultural burning and seed dispersal, to restore and protect landscapes over thousands of years?

Facilitation TipDuring Simulation: Cultural Burning Effects, use colored sand or markers to track how controlled burns change vegetation patterns and soil stability over time.

What to look forPose the question: 'How can we learn from the land management practices of Aboriginal and Torres Strait Islander peoples to help heal damaged environments today?' Facilitate a class discussion, encouraging students to share examples of traditional practices and their benefits.

Project-Based Learning60 min · Small Groups

Design Challenge: Restoration Plan

Assign degraded sites like a local farm or mine. In groups, research strategies including Indigenous methods, then draw and present plans with steps, materials, and expected outcomes. Peer vote on most feasible designs.

Design a land restoration plan for a specific degraded Australian environment that draws on both scientific methods and Indigenous ecological knowledge.

Facilitation TipDuring Design Challenge: Restoration Plan, require students to include both scientific and Indigenous methods in their proposals and justify each choice in writing.

What to look forOn an exit ticket, ask students to define 'land degradation' in their own words and list one scientific and one Indigenous method that can be used to reverse its effects.

Project-Based Learning40 min · Whole Class

Field Mapping: Schoolyard Erosion

Walk the school grounds to identify erosion spots. Students map areas, propose fixes like mulch or native plants, and install simple trials. Monitor changes weekly and adjust plans based on observations.

Explain how terracing and vegetation cover can reduce soil erosion on sloped and degraded land.

Facilitation TipDuring Field Mapping: Schoolyard Erosion, provide clipboards and simple tools like rulers or string to measure erosion features accurately.

What to look forProvide students with images of different degraded landscapes (e.g., a steep, bare hillside; a sandy coastal area). Ask them to write two sentences for each image explaining a specific strategy (scientific or Indigenous) that could help restore it.

A few notes on teaching this unit

Teach this topic by balancing direct instruction with inquiry, using demonstrations to introduce key concepts before students apply them hands-on. Avoid focusing only on problems; instead, highlight solutions and their long-term success. Research shows that when students test models or simulations, they better grasp cause-and-effect relationships in environmental systems.

Students will explain how specific techniques stabilize soil and restore land, compare Indigenous and scientific methods, and apply their learning to design practical solutions for local erosion issues. Success looks like clear explanations, accurate modeling, and thoughtful redesigns.


Watch Out for These Misconceptions

  • During Model Building: Terracing Erosion Prevention, watch for students who assume terraces solve erosion instantly without considering slope steepness or soil type.

    Ask students to adjust their models by changing slope angles or soil compositions, then observe and record how these factors affect soil retention. Guide them to conclude that terracing works best when tailored to specific conditions.

  • During Simulation: Cultural Burning Effects, watch for students who think cultural burning only reduces fuel loads without considering its role in seed germination and ecosystem regeneration.

    Have students compare burned and unburned sections of their simulation, noting changes in plant growth patterns. Ask them to explain how these changes support biodiversity and soil health in their lab reports.

  • During Field Mapping: Schoolyard Erosion, watch for students who believe erosion is only a problem in large, obvious areas like cliffs or farmland.

    Prompt students to look closely at small, overlooked areas like compacted soil near paths or bare patches under trees. Use their findings to discuss how local actions can add up to significant land degradation.
