What I Wish I Knew About Planning MYP Chemistry

Week 3 of Term 1, my Year 9s could balance equations but froze when I asked them to evaluate how a new biofuel might affect local water quality. That’s the MYP twist: concepts and contexts matter as much as content. In MYP Sciences, Chemistry lives under key concepts like Change and Systems, with related concepts (e.g., Energy, Interactions) and a Global Context that gives the lab a reason to exist. “On-topic” worksheets on acids might help with recall, but they miss if they don’t ask for the kind of thinking that Criteria A–D assess.

Common fit issues I see: command terms don’t match the markscheme, practicals lack a testable hypothesis and variables (Criterion B), or the reflection ignores societal impact (Criterion D). I keep my unit map and formative checks in ClassPods, then sanity‑check potential handouts against the Statement of Inquiry and summative task. If I’m still unsure, I scan what other science folks are using in the community library to see how they’ve woven concepts into routine skills practice.

Last Thursday my Year 10 group finished a salts worksheet that looked solid—until I realised every prompt said “state” or “label.” Fine for recall, weak for our Criteria A targets. Now I run four quick checks. One: do the questions actually use MYP command terms (describe, explain, evaluate) and invite structured responses? Two: is there any space for Criterion B thinking—variables, controls, or a fair-test prompt? Three: are data tasks set up so students can process and evaluate results (Criterion C), not just copy numbers? Four: does anything nudge them toward real-world impact (Criterion D)?

If I’m short on time, I paste the task into my ClassPods unit and add a mini‑prompt that forces the missing criterion—like a two‑minute “limitations and improvements” box beneath a data table. You can also spin up a sample, pathway‑aligned lesson pack to test these checks on your own materials here and see where your gaps are before photocopying.

Monday first period, my Year 9 MYP class was restless, so I used a quick, focused lab to nail concentration and rate. Key concept: Change. Global Context: Scientific and technical innovation. Statement of Inquiry: “Changes in particle interactions can be measured to inform innovation.” Worked example: the sodium thiosulfate and hydrochloric acid “disappearing cross.”

• Objective (3 min): Explain, using collision theory, how concentration affects rate; design and evaluate a fair test.
• Starter (7 min): Two photos—dilute vs concentrated solutions. Students describe differences, then predict which reacts faster and why.
• Main task (30 min): Groups plan and run the thiosulfate reaction at two concentrations. Force variables: independent (concentration), dependent (time to X disappear), controls (temperature, volume). Safety noted.
• Formative check (15 min): Process data into a simple table/graph; write one‑paragraph explain using collision theory; add two limitations and an improvement.
• Plenary (5 min): Exit slip using the command term evaluate on whether their data supports the prediction.

I build this as a ClassPods pack, so the command terms and mini‑rubrics sit right on the slides. If you want a ready scaffold to tweak for your room, you can spin one up in a couple of minutes here.

Two weeks before reports, my Year 8s hand in a digestion of an acid–metal lab that’s all results, no thinking. I now issue a one‑page, student‑friendly rubric/planner that mirrors Criteria B and C, plus a short D prompt. Drop this into your next investigation:

Title: How does [independent variable] affect [dependent variable] in [reaction]?

Criterion B: Inquiring and designing

• Question: Write a testable question using “How does… affect…?”
• Hypothesis + reasoning: “I predict… because (particle model/chemical principle).”
• Variables: Identify IV, DV, at least three controls; describe how you’ll control each.
• Method overview: Numbered steps with quantities and safety.

Criterion C: Processing and evaluating

• Data table/graph: Units, significant figures, and a neatly labeled graph.
• Explain: “The data show… This supports/does not support my hypothesis because…”
• Limitations & improvements: At least two realistic limitations; one specific improvement.

Criterion D (short): In 3–4 sentences, evaluate a real‑world impact connected to this reaction.

I paste this template into my ClassPods lesson so it travels with groups between benches. To see how other teachers phrase theirs, I browse the science community here and borrow language that fits my cohort.

The week before winter break, my Year 9 bilingual cohort (English/Spanish) hit a wall on “evaluate” versus “explain.” I now pre‑teach a tiny command‑term glossary in both languages and keep it visible during labs. During theory, I pair students intentionally—one leads the explanation in English, the other rephrases key nouns and verbs in Spanish, then we swap roles on the next question. On practicals, I chunk timing (10‑minute planning, 12‑minute run, 10‑minute processing) and collect a photo of the data table halfway through to curb drift.

Homework lives in a simple rhythm: one retrieval quiz (atoms–ions, covalent–ionic) and one short writing task that uses the week’s command term. For revision weeks, I assign mixed‑topic sets that force Criteria A–D in miniature—e.g., two data questions with a one‑paragraph evaluation. If you’re trying to fit all this to a budget before committing a department, the costs and what’s included are laid out clearly on the pricing page; I just built a shared calendar so we pace purchases with assessment windows.
