Coastal Care Reviews

Overview

This lesson is Lesson 15 of 24 in “Exploring Landforms and Landscapes”. Students evaluate how different coastal management strategies affect coastal environments and communities, building on earlier learning about geomorphological processes and human impacts on environments.

Learning intentions

Students will:

• analyse the interconnections between human activity and geomorphological processes in coastal environments
• evaluate strategies for managing coastal landscapes using environmental, economic and social criteria
• justify which coastal management strategy is most effective for a given case study

Success criteria

Students can:

• explain how a strategy changes erosion, sedimentation, or coastal landforms
• identify environmental, economic and social effects of the strategy
• compare two strategies using evidence from the case study
• write a justification that clearly states a recommendation and reasons

Curriculum links

• AC9HG8K04: the interconnections between human activity and geomorphological processes, and ways of managing distinctive landscapes
• AC9HG8S05: identify a strategy for action… and explain potential impacts
• AC9HG8K01: geomorphological processes that produce different landscapes and significant landforms (linking coastal landforms to erosion/transport/deposition)

Lesson structure (45 minutes)

1. 0–5 min · Hook conversation. Teacher displays two quick prompts: “Why do people build walls/rocks on beaches?” and “What might go wrong?” Students think-pair-share, then share one idea to the class.

2. 5–12 min · Mini-lesson: what “effective” means. Teacher summarises three evaluation lenses (environmental, economic, social) and links them to coastal processes (erosion and sediment movement) using a simple diagram (no digital required). Students record a one-sentence definition for each lens in their books.

WALT: Evaluate the effectiveness of different coastal management strategies by using environmental, economic and social criteria.

3. 12–22 min · Case study analysis (strategy A vs B). Teacher hands out a one-page case study pack with two strategies (examples: beach nourishment/reprofiling vs seawall/groyne system; or dune fencing/vegetation vs sand extraction controls). Students work in pairs to complete a comparison table: “How it works” → “Likely coastal impacts” → “Likely community impacts”.

4. 22–30 min · Whole-class sense-making (guided discussion). Teacher selects 3 student pairs to share one “best evidence” point each, and uses prompts: “What process is happening here?” “What impact is most important—why?” Students add one new idea to their comparison table.

5. 30–41 min · Justification writing (individual). Teacher models a short plan (claim → reasons → evidence from table → conclusion). Students write a 1-paragraph justification recommending the strategy they believe is most effective, using provided sentence frames. Students must include at least: one environmental reason, one social or economic reason, and one explanation of how the strategy affects coastal processes.

6. 41–45 min · Exit ticket check. Students complete an exit ticket: “My recommended strategy is ___ because ___ (environmental) and ___ (social/economic).” Teacher quickly checks for alignment to criteria.

Resources

• Case study pack: Strategy A and Strategy B (print)
• Comparison table template (print)
• Justification paragraph template with sentence frames (print)
• Coloured pencils or highlighters (for lens coding: environment/economy/society)
• Diagram showing erosion/transport/deposition and how strategies affect it (teacher-made on board or chart)
• Timer and model paragraph on display (visualiser or board)

Assessment

• Formative: teacher listens during pair/table work and discussion, checking students can link strategy to processes (erosion/sedimentation)
• Formative: check completed comparison tables for balanced lens coverage
• Summative for today: the justification paragraph and exit ticket (clarity of recommendation + justified reasons)

Differentiation

• Sentence frames for everyone (especially support):
• “I recommend ___ because it affects ___ by ___.”
• “This is likely to improve ___ (environmental/social/economic) since ___.”
• “Compared with ___, this strategy is more effective because ___.”
• Support for learners needing structure: provide a partially filled comparison table (one row pre-completed) and a checklist for paragraph requirements.
• Extension: ask students to include one limitation/trade-off (“This strategy may not be effective if…”) and propose a modification.
• EAL support: allow first draft using key words from the table, then students add linking sentences using frames.
• Dyslexia-friendly reading options:
• provide the case study in double-spaced print with larger font
• read-aloud option for the case study pack while students follow on a copy
• optional audio recording of the case study provided by the teacher (offline, no internet required)

Differentiation (as assessment support)

• Teacher uses a quick “lens check” during writing: students highlight at least one sentence for environment and one for social/economic.
• Offer a brief 2-minute teacher conference for students whose paragraphs lack explicit justification (re-teach claim-reason-evidence with one example).
