What IB · PYP Biology Really Looks Like in My Classroom

Last Monday in Week 5 of our Sharing the Planet unit, my Year 4s brought in photos of snails from the courtyard and declared we had a “snail problem.” That moment only works if biology sits inside the unit’s central idea and lines of inquiry—here, interdependence and limited resources—not as a standalone “Living Things” worksheet set. In PYP, the science strand is about constructing understanding through concepts like connection and causation, then asking, “So what’s our responsibility?”

Here’s where many on-topic resources miss: they teach parts of a plant beautifully, but never invite students to test function or consider change over time. They’ll list “habitat,” but skip student-generated questions, action, or reflection. I look for provocations, not instructions; iterative investigations, not one-and-done labs; and success criteria that value explanation and evidence.

When I hunt for something to adapt, I start with transdisciplinary fit: does it speak to the unit’s central idea in generalizable language, or is it locked to a narrow fact set? If I need a springboard, I skim community science materials and park promising leads in the library so I can remix them around our lines of inquiry.

Back in March, my Year 5s were fixated on “camouflage” after a playground game. I nearly grabbed a slick predator-prey pack, but a five-minute audit saved me. First, I scan for PYP vocabulary moves: a central idea phrased as a transferable generalization (“Organisms use structures and behaviors to survive”), not a statement of facts. Then I check for key and related concepts; if form, function, and causation aren’t explicit, I make them so.

Next, I hunt down ATL skills and learner profile links—are there prompts for collaboration, research, and reflecting on evidence? Then the assessment style: are there success criteria tied to explanation quality and data use, not just labeling? Finally, I want an action invitation, even a small one, like redesigning a terrarium to improve conditions.

When I don’t see those, I either adapt or build. I’ll draft a provocation, weave in bilingual sentence stems, and note a reflection question. If you want to prototype a lesson and stress-test its language and criteria, you can generate a skeleton and tweak it in the lesson creator. I keep a running bank of prompts and reflections in ClassPods so I can reuse what actually worked.

Last Thursday my Year 3 group circled a single rosemary bush covered in bees and asked, “Why this plant?” That became our worked example for pollination and structure–function inside How the World Works. I framed everything through causation and connection, not trivia.

Objective: Explain how flower structures support pollinators, using evidence from observation.
Worked example: Pollinators on the courtyard rosemary vs. a nearby ornamental grass.

• 0–7 min Starter: Photo provocation + quick notice/wonder in pairs; build a bilingual word bank (stamen, nectar, scent).
• 7–25 min Main Task Part 1: Field-note observations (color, scent, nectar guides). Sketch and label; prompt: “How might this feature help?”
• 25–40 min Main Task Part 2: Quick test—place a white paper under flowers, tap gently, observe pollen dust; record.
• 40–50 min Formative Check: 3-question mini-conference—What evidence did you collect? Which structure supports which function? What’s your remaining question?
• 50–60 min Plenary: Whole-class concept map (structures → pollinator behavior → plant success) + action idea: add native pollinator plants to our planter box.

I’ll generate a rough outline in ClassPods, then localize the phenomena and language. If you want to spin up this structure fast, you can create a draft pack here and tune it to your unit’s central idea.

Two weeks ago my Year 6s compared compost bin microhabitats and needed clearer expectations. I handed them this rubric and journal template—simple, PYP-fluent, and ready for bilingual classes.

Investigation Rubric (Levels: Emerging / Developing / Secure / Extending)

• Question & Concept: States a testable question linked to function or causation. (E: vague fact; D: simple cause; S: clear cause/effect with variable; X: connects to system interdependence)
• Plan & Fair Test: Controls variables; predicts with reason. (E: missing controls; D: some controls; S: appropriate controls; X: justifies design with prior evidence)
• Evidence & Records: Uses labeled diagrams/tables. (E: scattered notes; D: partial table; S: complete, accurate; X: includes error checks/replicates)
• Explanation: Uses data to explain structure–function. (E: claim only; D: claim + one reason; S: claim–evidence–reasoning; X: considers alternative causes)
• Action & Reflection: Proposes and justifies an action. (E: generic; D: plausible; S: specific, evidence-linked; X: anticipates impact on others)

Journal Stems: “Today I noticed…”, “This feature might help because…”, “Our evidence shows…”, “Next time we will…”, “In my home language, this idea connects to…”. If you like to keep exemplar rubrics handy, I park a clean copy in my library and duplicate per group.

This term my mixed Year 4/5 class has three new arrivals who prefer Spanish at home. I front-load a bilingual picture glossary with icons, then offer sentence stems at two levels: “I notice…” and “This structure helps because…”. Partner roles rotate—Observer/Interpreter—so students can think in their strongest language before sharing out. Slower processors get a pre-brief of vocabulary; faster groups extend by designing a mini-investigation with one added variable.

For pacing, I chunk field notes into 6–8 minute bursts with a visible timer and a “freeze-to-sketch” cue. My formative check uses colored counters: green for “I can match a structure to a function,” yellow for “I’m close,” red for “I need a model.” That lets me huddle a quick clinic while others map connections.

Homework isn’t a packet; it’s a short “home biodiversity scan” with photos or quick sketches, plus a one-sentence claim backed by a hint of evidence. For revision, I use spaced retrieval: weekly two-minute oral prompts pulled from last month’s word bank. I save bilingual versions in ClassPods and update stems after each cycle. If you want a head start, you can generate a home-learning slip in a fresh draft pack.
