Curriculum Alignment

• Australian Curriculum v9 – Science Understanding:
  • AC Bio Unit 3: Understand biodiversity and ecosystems, including the effects of environmental changes and conservation strategies.
  • Develop knowledge of evolutionary processes and their impact on biodiversity.
• Science Inquiry Skills and Nature of Science:
  • Engage in planning and conducting scientific investigations focused on biodiversity.
  • Analyse and interpret data related to biodiversity in ecosystems.
• Cross-curriculum priorities:
  • Recognise First Nations Australians’ knowledges and contributions about biodiversity and ecosystem management.

Learning Objectives

By the end of this lesson, students will be able to:

1. Analyse how biodiversity is defined and measured within Australian ecosystems, recognising species richness and genetic diversity.
2. Evaluate the evolutionary processes (natural selection, adaptation, extinction) that influence biodiversity.
3. Investigate the impact of environmental changes, including human activity, on biodiversity and ecosystem health.
4. Assess conservation strategies and their effectiveness, incorporating Indigenous perspectives and science communication.
5. Apply scientific inquiry skills to collect and interpret biodiversity data.
6. Reflect on ethical considerations and cultural worldviews in biodiversity science.

Lesson Breakdown

1. Introduction: Biodiversity Deep Dive (10 minutes)

• Activity: Interactive brainstorming with class to define biodiversity — species, genetic, and ecosystem diversity.
• Context provided: Importance in Australian ecosystems; link to evolutionary theory and ecosystem functions.
• Curriculum Connection: Understanding biodiversity and evolution (AC9S10U02_E2: examining biodiversity as a function of evolution)【8:AC9S10U02.md】; awareness of First Nations contributions【17:AC9S7H02.md】.

2. Investigating Biodiversity through Inquiry (20 minutes)

• Activity: Using provided datasets—simulate a field investigation of local biodiversity through species counts, habitat types, or genetic data (digital or printed).
  • Students fill tables and construct graphs to identify patterns, trends, or disturbances in biodiversity.
• Tools: Use of digital tools or graphs to organise data visually.
• Curriculum Alignment: Engage in scientific investigation and data analysis (Science Inquiry Skills), with emphasis on reproducible, valid methods【3:AC9S9I02.md】.
• Inclusivity: Highlight Indigenous ecological knowledge and practices in biodiversity management during dataset analysis【17:AC9S7H02.md】.

3. Evolution and Biodiversity — Case Study (10 minutes)

• Activity: Short presentation and discussion on how natural selection impacts biodiversity using a local example (e.g., Australian native species adapting to environmental pressures).
• Task: Students discuss adaptive traits and evolutionary pressures, linking these to biodiversity changes.
• Curriculum Focus: Natural selection and biodiversity relationship (AC9S10U02_E1, E2, E4)【8:AC9S10U02.md】.

4. Human Impact and Conservation Strategies (10 minutes)

• Activity: Small group discussions on human impacts (e.g., habitat destruction, climate change, invasive species) and review real-world conservation efforts including Indigenous-led initiatives.
• Prompt: Groups evaluate effectiveness, ethical considerations, and societal influences on scientific research and policy.
• Link to Curriculum: Values and societal needs influence scientific research and conservation (AC9S9H04)【19:AC9S9H04.md】.
• Incorporate: Role of science communication in changing community perspectives and policies【15:AC9S7H04.md】.

5. Formative Assessment & Reflection (10 minutes)

• Activity: Individual reflection worksheet:
  • Students write a short response evaluating a conservation strategy they learned, including Indigenous perspectives and scientific principles.
  • Include a scientific question or hypothesis they might test in future biodiversity research.
• Outcome: Assessment of understanding combining science content and inquiry skills.

Resources Needed

• Digital or paper datasets illustrating biodiversity in a local ecosystem
• Graph paper or digital graphing tools
• Presentation slides summarising evolution and conservation examples
• Reflection worksheets with guided prompts
• Access to recorded Indigenous ecological knowledge excerpts or written summaries for cultural context

---

Differentiation and Engagement Strategies

• Provide data sets at varying complexity levels
• Use discussion prompts to engage all students including leadership roles for quieter students
• Incorporate multimedia Indigenous knowledge sources for cultural inclusivity
• Use real-world Australian biodiversity examples to maintain relevance
• Scaffold scientific vocabulary and encourage peer discussion for language support

Summary

This highly aligned lesson plan leverages curriculum content such as evolutionary biology, scientific investigation methods, societal influences on science, and Indigenous knowledges to engage Year 12 Biology students in an insightful exploration of biodiversity. The combination of inquiry, case studies, group discussions, and reflective assessment ensures a rich learning experience within a 60-minute timeframe. The focus on reproducibility, ethical issues, and culture meets the Australian Curriculum (v9) Science standards excellently, preparing students for deeper learning in Unit 3 Biology.
