Coastal Life Detectives

Overview

This is lesson 1 of 10 in the unit Resilient Coastal Life. Students investigate photographs and real objects from the local Dunedin coast, identify familiar plants and animals, group them by observable features, and record where they live.

Learning intentions

• WALT identify plants and animals found in a local coastal environment.
• WALT classify living things using observable features.
• WALT record where coastal plants and animals live.
• WALT use scientific words and observations to share ideas.

Success criteria

• I can name at least three local coastal species.
• I can group plants and animals using an observable feature.
• I can describe where a coastal living thing lives.
• I can explain one reason for my grouping.

Curriculum links

• Living World—life processes: recognise that all living things carry out life processes.
• Living World—ecology: explore how living things are suited to and interact with their coastal environment.
• Nature of Science—communicating in science: use observations, drawings, words and maps to share findings.
• Key competencies: thinking; managing self; participating and contributing; relating to others.

Lesson structure (45 minutes)

1. 0–5 min — Hook and visual lesson sequence Display a striking photograph of a Dunedin rock pool and ask: “What living things might be hiding here?” Open the introduction and hook slides and explain the visual sequence: look, sort, map, share. Students quietly notice and then share one observation with a partner.

2. 5–12 min — Explicit teaching and modelling Show photographs and real, clean beach objects such as shells, seaweed, stones and driftwood. Clarify that a plant or animal is a living thing, while a shell or stone is an object or remains. Model identifying a pāua, kina, mussel, limpet, sea lettuce, gull and shag, using the local species photographs in the local coastal species slides. Think aloud: “I can see a hard shell and a low shape, so I will group this limpet with other shelled animals.”

3. 12–25 min — Beach-life sorting activity Place pairs or groups of three with a mixed set of teacher-prepared photograph cards and safe real objects. Distribute the coastal life observation and sorting sheet. Students sort the items first into plants, animals and not-living objects, then make a second grouping using an observable feature, such as shell/no shell, attached/moving, or found in water/on rocks. Remind students that more than one grouping can be sensible if they can explain it. Pause halfway to model a complete sentence: “We grouped these together because they have…”

4. 25–34 min — Habitat recording Introduce simple habitat areas on the class map: rock pools, rocky shore, sandy beach, seaweed area and shallow water. Groups place or draw their species in an appropriate area on their worksheet, adding a word or short phrase about its needs, such as water, shelter, food or a firm surface. Offer oral recording, drawing, scribing or speech-to-text instead of requiring full sentences.

5. 34–41 min — Shared class map On a large outline map of the local coast, invite groups to add one species and explain its location. Open the habitat map and discussion slides to prompt: “What might happen if this habitat changed?” and “Which animals might depend on seaweed or rock pools?” Accept supported responses and help students distinguish a likely habitat from an exact location.

6. 41–45 min — Review and formative check Revisit the success criteria and plenary slides. Students show fingers from one to three to indicate how confidently they can name, group and locate coastal life. Each student tells a partner one species, one observable feature and one habitat; the teacher records examples and misconceptions to guide lesson 2.

Resources

• the introduction, teaching, activity, map and plenary slide deck
• the coastal life observation and sorting sheet
• Teacher-prepared photograph cards of local coastal plants, animals and non-living objects
• Clean, safe real objects such as shells, seaweed, stones and driftwood
• Large paper outline map of the Dunedin coastline or local beach area
• Blu Tack, magnets, pencils, coloured pencils and group trays
• Visual lesson sequence: look, sort, map, share
• Large-print, uncluttered species fact cards with short sentences
• Optional audio or text-to-speech access for fact cards

Assessment

• Observe whether students correctly identify living and non-living items and record evidence in the sorting sheet.
• Listen for use of observable features to justify groupings, noting students who need support with classification language.
• Check the shared map and habitat explanations for a reasonable connection between each species and its coastal environment.

Differentiation

• Provide picture-and-word cards, explicit modelling, colour-coded categories and sentence frames such as “I grouped ___ with ___ because…”.
• Allow oral answers, drawing, pointing, partner scribing, reduced writing and teacher or peer transcription. Use a visual lesson sequence and give one instruction at a time.
• Support dyslexic learners with teacher-read text, large-print fact cards, short sentences, cream or pastel backgrounds, uncluttered layouts, audio and text-to-speech options.
• Support the student with Down syndrome through a consistent partner, repeated key vocabulary, concrete objects, choice of two or three responses, extra processing time and frequent positive feedback. Extend confident learners by asking them to compare two habitats and explain which needs each species has.
