Biodiversity Stewardship

Overview

This double lesson supports students to complete a prior worksheet on Creation, Biodiversity and Stewardship, then explicitly teaches the importance of natural environments for maintaining biodiversity. Students analyse how biodiversity supports biological resources, ecosystem services, and social benefits, using a biblical creationist perspective alongside scientific reasoning suitable for Stage 5 (Year 9–10).

Learning intentions

• Students will complete the Creation, Biodiversity and Stewardship worksheet using evidence and clear explanations.
• Students will explain why healthy biodiversity matters for maintaining natural environments.
• Students will describe benefits of biodiversity to biological resources and ecosystem services.
• Students will analyse how biodiversity contributes to social benefits for communities.
• Students will connect these ideas to a biblical creationist perspective (care for creation as stewardship).

Success criteria

• I can complete the worksheet with accurate, specific examples and reasons.
• I can define biodiversity and explain how it supports ecosystem stability.
• I can give examples of ecosystem services (provisioning, regulating, cultural/supporting) and link them to people’s lives.
• I can explain social benefits of biodiversity (health, recreation, livelihoods, cultural connections) using scientific and stewardship-based reasoning.

Curriculum links

• Social sciences focus (analysis of human–environment relationships through sustainability lens): consistent with SC5-ENV-01 students analyse the impact of human activity on the natural world.
• Environmental sustainability content: maintains the natural world by focusing on biodiversity and its role in sustainability.
• Skills and competencies (explicitly taught and used): questioning, interpreting information, and explaining cause-and-effect relationships in real-world contexts.

Lesson structure (total minutes: 80)

1. 0–5 min · Set-up and goals. Teacher displays lesson title and WALT, briefly reviews expectations for respectful discussion and evidence-based answers. Students unpack materials and write today’s WALT and success criteria into books.

2. 5–20 min · Independent video and worksheet activity. Students watch the embedded YouTube videos on biodiversity stewardship independently:

• Video 1
• Video 2
• Video 3

They then complete the "Creation, Biodiversity & Stewardship" worksheet, using the video content to support their answers. Teacher circulates to assist as needed, maintaining a casual facilitation style.

3. 20–45 min · Worksheet completion continuation and collaboration. Students continue and complete the worksheet independently, then collaborate briefly (if stuck) to complete the worksheet.

4. 45–50 min · Break. Teacher releases students for a short break. Students take a restorative break and return on time.

5. 50–62 min · Explicit teaching: Importance of natural environments. Teacher gives a structured mini-lesson using clear examples and a simple organiser: (a) biodiversity → ecosystem function, (b) biological resources, (c) ecosystem services, (d) social benefits; then states and frames a biblical creationist perspective as stewardship: caring for what was created. Students copy a guided notes organiser and contribute 2–3 examples during teacher pause-points.

6. 62–73 min · Structured analysis task: Ecosystem services and social benefits. Teacher models one worked example (e.g., pollinators → crop yields → food security → livelihoods) and provides sentence starters. Students complete a “Biodiversity → Services → People” table in pairs, choosing one ecosystem example (local bushland/river/coast imagined or described by the teacher).

7. 73–75 min · Differentiated independent tasks related to videos.

• Lower ability: Complete a simplified summary worksheet identifying key points from each video using sentence starters and visuals.
• Higher ability: Create a short presentation comparing the three videos’ perspectives on biodiversity stewardship, including personal reflections and stewardship actions.

8. 75–80 min · Exit ticket and wrap. Teacher reads the prompt aloud twice and emphasises evidence + stewardship link. Students answer individually: “Explain one benefit of healthy biodiversity to ecosystems and one social benefit to people. Include a short stewardship statement.”

Resources

• Creation, Biodiversity and Stewardship worksheet (completed first segment)
• Guided notes organiser (ecosystem services categories + examples)
• “Biodiversity → Services → People” table (one per student or shared per pair)
• Sentence starters and word bank (biodiversity, ecosystem services, provisioning, regulating, cultural, stewardship, care, resources, livelihoods)
• Coloured highlighters for coding ecosystem-service types
• Dyslexia-friendly reading options: printed short text with larger font, plus an audio-enabled version if available
• Timer and visible WALT/success criteria poster
• Embedded YouTube video: https://www.youtube.com/watch?v=rVZktiOxsww

Assessment

• Formative during worksheet completion: teacher scans for accuracy, use of evidence, and clarity of explanations.
• Formative during table task: teacher checks service categories and whether social benefits are linked to biodiversity outcomes (cause-and-effect).
• Summative quick check (exit ticket): evaluate whether students meet all key success criteria (definition/importance, ecosystem services, social benefits, stewardship connection).

Differentiation

• Support for learners who need scaffolding: provide partially completed templates, sentence starters, and a word bank; allow responses in short bullet points before writing full sentences.
• Dyslexia-friendly reading options: provide a shorter, high-contrast text summary of ecosystem services; allow audio read-aloud of notes; offer extra time for reading the exit ticket prompt.
• For students needing language support: teacher model-worked example using clear visuals; pair with a supportive peer and allow “swap and check” for accuracy.
• Extension for advanced learners: challenge students to compare two ecosystem scenarios (healthy vs degraded biodiversity) and predict two knock-on effects for services and social benefits, then add a brief stewardship “action implication” paragraph.
