Caring for Land

Overview

Students explore a local land environment (school grounds or nearby greenspace) to investigate how living things interact with their habitat. They connect their observations to ecosystem functioning and land conservation.

Learning intentions

• Students will observe and describe abiotic and biotic features of a land environment.
• Students will explain how ecosystems are organized (producers, consumers, decomposers) and how energy/matter flow through food relationships.
• Students will identify human impacts on land ecosystems and propose practical conservation actions.
• Students will use simple data-collection methods to support scientific claims.

Success criteria

• I can list biotic and abiotic factors I observe and describe how they affect where organisms live.
• I can create a simple food web (at least 4 organisms) based on evidence from the environment.
• I can explain at least two ways humans can harm or help land ecosystems.
• I can justify my conservation suggestion using observations and reasoning.

Curriculum links

• Science and technology: investigating living things and their environments through observation and classification
• Science and technology: understanding ecosystems and interactions within habitats
• Cross-curricular competencies: Uses information, Solves problems, Exercises critical judgement, Communicates appropriately
• Environmental stewardship: recognizing the role of human actions in ecosystem health and sustainability

Lesson structure (60 minutes)

1. 0–5 min: Launch question + safety

• Teacher shows 2–3 photos or short examples of land habitats (forest edge, meadow, park soil).
• Students discuss: “What makes this place a good habitat for some organisms?”

2. 5–12 min: Quick mini-lesson—land ecosystems

• Teacher explains key ideas: biotic/abiotic factors, habitat, ecosystem, and food relationships.
• Students review roles: producers (plants), consumers (animals), decomposers (many fungi/bacteria—observed indirectly by leaf litter and soil).

3. 12–18 min: Fieldwork setup (plan and roles)

• Form small groups (3–4 students). Assign roles: recorder, counter, sketcher, spokesperson.
• Teacher models a simple transect method: choose a line/path and record what is found at set intervals.
• Remind students to use careful observation (no disturbing organisms beyond what is necessary).

4. 18–38 min: Land exploration (natural environment)

• Students investigate outdoors in a selected area for ~20 minutes.
• At each interval, groups record: visible plants, insects/other animals (if seen), signs (tracks, webs, droppings), and abiotic features (light, moisture/soil type, leaf litter, rocks, wind exposure).
• Teacher circulates with guiding questions: “What evidence shows organisms are using this habitat?”

5. 38–45 min: Data check + first claims

• Groups return to class and quickly organize notes into a table: biotic vs abiotic factors, plus “evidence”.
• Each group states one preliminary claim: “Because we observed __, we think __ affects where organisms are found.”

6. 45–55 min: Build a simple food web

• Groups choose 4–6 organisms from their observations (or closely related organisms if something cannot be identified to species).
• Teacher provides a food-web template: draw arrows showing “is eaten by” relationships.
• Students also add one decomposer link using indirect evidence (leaf litter, soil organisms) and label it as decomposers.

7. 55–60 min: Conservation action exit ticket

• Individually, students write a short plan: one threat they noticed or inferred (e.g., litter, compacted soil, trampling, invasive plants, lack of native plants) and one action to protect land habitat at school or home.
• Teacher collects exit tickets for assessment.

Resources

• Clipboards, paper, and pencils for field notes
• Simple observation sheets (biotic/abiotic table, “evidence” column)
• Student-made transect string or tape measure (optional)
• Magnifying glasses (optional)
• Hand sanitiser and tissues; gloves if handling leaf litter is needed (teacher discretion)
• Food-web template (printed) or large paper for groups
• Timer for fieldwork intervals
• Reference picture cards of common local land organisms (optional)
• Classroom projector or printed photos for the launch

Assessment

• Teacher observation during fieldwork using a quick checklist: participation, careful recording, respectful handling.
• Formative assessment: group food web evaluated on accuracy of food relationships and use of observation evidence.
• Summative/exit ticket: conservation action scored with a simple rubric (claim + reasoning + feasibility).

Differentiation

• Support:
• Provide sentence starters: “We observed…”, “This suggests… because…”, “A conservation action could…”
• Offer organism picture cards to help with identification.
• Use a partially completed biotic/abiotic table for students who need structure.
• Extension:
• Challenge students to include an additional trophic level or justify decomposer role more explicitly using leaf/soil evidence.
• Ask for a cause-and-effect statement: “If abiotic factor X changes, organism Y likely changes its location/abundance.”
• EAL:
• Allow students to record observations with drawings and labels, then add a short sentence in any supported language structure.
• Pair EAL learners with a supportive peer role (sketcher or recorder with picture prompts).
• SEN:
• Break tasks into smaller steps: interval record → class table → food web arrows.
• Reduce the required number of organisms for the food web (e.g., minimum 4) while maintaining evidence-based reasoning.

Extension (optional)

If you’d like, the class can design a simple “Habitat Care” display for the school (poster or sign) based on their observations and conservation proposals.
