Drain Bugs

Overview

Students explore drains and bug environments through short, hands-on observation, sensory play, and simple science talk. The lesson builds understanding of living things in places that meet their needs, while practising asking questions and sharing observations in a supportive way.

Learning intentions

• Students will observe small living things in different bug habitats (including near drains) and describe what they can see.
• Students will explore how drains provide conditions bugs use (water, shelter, food/decay).
• Students will ask and answer simple questions about bugs and their environments using support.
• Students will share observations or ideas using gestures, pictures, objects, or single words.

Success criteria

• I can look closely at a bug or bug habitat and say/show what I notice.
• I can sort or place objects to show “bug homes” versus “not bug homes”.
• I can make a simple prediction: “I think bugs like…” using a sentence starter or picture.
• I can share what I observed using a picture card, pointing, or a word.

Curriculum links

• Science — describe how places meet basic needs of living things (air, water, food, shelter) through Year Pre-primary learning progressions.
• Science — pose questions and make predictions based on observations (adapted with picture supports and guided prompts).
• Science — share questions, predictions, observations and ideas with others using everyday and scientific vocabulary (adapted with non-verbal communication options).

Lesson structure (45 minutes)

1. 0–5 min · Welcome routine + sensory regulation. Teacher sets a calm visual schedule (pictures) and does 1 minute of deep-pressure or heavy-work (e.g., push a soft tub, carry a “bug toolkit” bag) to support regulation; student chooses a comfort item.

2. 5–10 min · Hook with drain pictures + interest check. Teacher shows 3–4 large images of drains in different places (street grate, garden drain, stormwater area) and 2–3 bug pictures; teacher asks one question at a time (“Where do you think bugs are?”) while offering a choice board (point to “near drain” / “not near drain”).

3. 10–18 min · Guided observation: “Bug hunt” (safe, simple). Teacher takes the student to a safe outdoor or indoor “drain zone” (near a container that has leaf litter/soil, or a prepared tray). Teacher uses a clear observation routine: look → touch (if safe) → listen → point. Student watches for small creatures (e.g., tiny worms, beetle larvae if present, pill bugs in leaf litter) or observes signs of life (holes, tiny droppings, webbing). Teacher labels only what is seen: “I see a worm” / “I see leaf pieces”.

4. 18–25 min · Exploration of drains (hands-on models). Teacher provides a simple drain model: a clear plastic gutter/pipe section with removable “grate” and 2 trays (dry leaves; damp leaves with a little water). Student uses tools (small scoop, soft brush) to move materials and observe. Teacher prompts: “What is in the drain?” and offers picture answers: water, leaves, mud, shelter.

5. 25–32 min · Sensory play station: “Bug feeling tray”. Teacher sets one tray with safe textures: damp soil/leaf mould, small stones, and water spray mist (optional). Student explores with gloves or bare hands depending on sensory needs. Teacher introduces consistent, calm phrases: “Wet”, “Dry”, “Soft”, “Under”. Student chooses a sensory strategy: slower touch, gloves, or smelling only (no strong smells).

6. 32–38 min · Question + prediction using a “Because” prompt. Teacher holds up two habitat cards (e.g., “damp leaves in drain” and “dry sand”); asks: “Where will a bug feel safe?” Student selects one card. Teacher supports a simple prediction sentence using choice: “I think bugs like ____ because ____” with picture options (because it has water / shelter / food/decay).

7. 38–45 min · Share observations + wrap-up. Teacher and student do a quick “science sharing” using a mini communication tool: photo/pointing sheet or 3 picture icons (“I saw…”, “I think…”, “I noticed…”). Teacher repeats back the student’s choice in clear language. End with a closing action: wash hands, return items, place the student’s “today’s science” picture on the class wall.

Resources

• Visual schedule cards (start/steps/end) with the same icons each time
• Large drain and bug habitat pictures (printed)
• Safe observation trays: damp leaf litter/soil in a shallow tray; dry tray; small stones
• Simple drain model (transparent gutter/pipe section) with removable grate-like cover
• Tools: soft brush, small scoop, tweezers for teacher only, spray bottle (optional)
• Sensory tray materials: damp soil/leaf mould, dry leaves, small stones, water in a separate cup
• Gloves (sensory option), wipes, handwashing station supplies
• Bug habitat sorting cards (“damp drain home”, “dry not a home”)
• Student communication supports: picture sentence starters, choice board, pointing sheet

Assessment

• Observation checklist: student engages with habitat items, can point to what they notice, and participates in one question/prediction choice.
• Running verbal/visual record: teacher notes what was observed (e.g., “leaf litter”, “wet mud”, “shelter under leaves”) and student’s selected prediction card.
• End-of-lesson sharing (1–2 responses): “I saw…” and “I think…” captured by pointing or a single word.

Differentiation

• Communication support: use yes/no and two-choice questions; accept pointing, gestures, and picture selection; limit to one prompt at a time.
• Scripted language + wait time: teacher uses the same repeated sentence starters (“I see…”, “I think… because…”), with immediate modelling.
• Sensory needs: provide glove option, reduced texture exposure, and choice of activity intensity (touch briefly vs explore freely). Offer movement breaks (push/pull containers).
• Attention support: short cycles (6–8 minutes) with clear transitions; keep materials visible and contained; use a timer.
• Safety and predictability: prepare “no touch unless teacher says” rules; teacher handles any uncertain organisms; keep the environment consistent.
• For extension within the same task: if the student is ready, offer a third choice card (“near water”, “under leaves”) and ask a second prediction.

Literacy integration (built into science)

During observation and sharing, teacher uses a drain-bug themed “talk and label” routine:

• Teacher names key nouns: drain, water, leaves, mud, shelter, worm/bug (only if seen)
• Student completes one literacy action: point to a noun card, match a picture, or place a sticker under “I saw”.
• Teacher models question words with pictures: “Where?”, “What?”, “Why?” using Because options (water/shelter/food/decay).
