Learning Objectives

Aligned with the Victorian Curriculum Humanities and Social Sciences (HASS) for Year 3, this lesson enables students to:

• Identify human activities—such as agriculture, urban development and industrial use—and describe how they affect local water sources (Victorian Curriculum Code: AC9HS3K05, Geography strand).
• Collect and record information from case studies to understand environmental impact on water sources (AC9HS3S02).
• Work collaboratively in small groups to discuss and communicate findings, developing geographical inquiry skills (AC9HS3S03).
• Reflect on the implications of changes in water for people, animals and environments, linking to the importance of sustainable management (cross-referenced with AC9HS4K05 for environmental importance).

Curriculum Links

• HASS Geography Year 3: Understanding natural, managed, and constructed features of places, focusing on human impact on local environments and resources (AC9HS3K05, AC9HS3S02, AC9HS3S03).
• Inquiry skills: Locating, collecting, recording, and interpreting data from various sources – including maps, photographs, and case studies.
• Personal and Social capability: Cooperation and communication in small groups.

---

Resources Needed

• Printed or digital case studies describing local examples of agriculture and urbanisation impacting water sources (e.g., a nearby river or lake affected by farming runoff or urban waste)
• Large paper, markers, and sticky notes for group work
• Prepared worksheet guiding inquiry questions to analyse case studies
• Maps or photos showing local water bodies and land use changes
• Whiteboard or interactive board

Lesson Activities

1. Introduction and Engagement (10 mins)

• Begin with a brief discussion: "Where does our water come from?"
• Show a simple local map highlighting a nearby water source (e.g., river, lake).
• Pose the inquiry question: "How do you think human activities like farms or buildings affect our water?"
• Share a short video or story (2–3 mins) illustrating an impact of human activity on water (e.g., algae blooms from fertiliser run-off).

2. Inquiry-based Case Study Research in Groups (25 mins)

• Divide students into 5 groups of 5.
• Each group receives a different case study about a local or relatable water source affected by human activity—either agriculture (runoff, pesticide use) or urbanisation (pollution, drainage changes).
• Provide guiding questions on a worksheet:
  • What human activity is described?
  • How has this affected the water source?
  • What might this mean for the people and animals that use this water?
• Students read or listen to the case study, discuss in their group, and record answers.
• Teachers circulate to support and prompt deeper thinking.

3. Group Sharing and Discussion (15 mins)

• Each group presents their findings briefly (3 mins each).
• Encourage other groups to ask questions or add ideas.
• Teacher facilitates linking ideas and highlighting the different impacts (pollution, reduced water quality, changing water availability).

4. Whole Class Reflection and Wrap Up (10 mins)

• Using the whiteboard, co-create a mind map titled "Human Impact on Water" with student input, listing activities and effects.
• Discuss how these impacts affect people and the environment now and in the future.
• Invite students to suggest ways humans can protect water sources for everyone.

Assessment and Feedback

• Formative Assessment: Observe group discussions and presentations for understanding of human impact on water sources.
• Worksheet Completion: Review students' recorded answers for comprehension of case studies.
• Reflective Question: "Can you name one way we can help keep our water clean?" – verbal or written response.

---

Differentiation Strategies

• Provide audio versions or simplified text for students needing support.
• Challenge advanced students to think about long-term environmental effects and suggest detailed water-saving strategies.
• Use visual aids and graphic organisers for students who benefit from structured notes.

---

Extensions and Cross-curricular Links

• Link to Science: Explore local water cycle components affected by human activities (vapour, condensation changes due to pollution).
• Maths: Graph the types of impacts found in each case study or compare water quality measures if data is available.
• English: Use descriptive language when presenting findings, focusing on precise vocabulary: pollution, runoff, ecosystem, sustainability.

This lesson plan is designed to WOW teachers by combining inquiry learning, group collaboration, curriculum alignment, and real-world relevance tailored for Year 3 students, making geography tangible and engaging through local water issues linked directly to their community and environment.
