Science in the MYP rarely fails because a student “doesn’t know enough.”
It fails in a quieter way: you know the chapter, you can recite the definitions, you even remember the diagram… but the task asks you to use the idea in a new context, justify a method, or evaluate evidence like a scientist. That gap between knowing and using is where most marks go missing in MYP Sciences.
This guide is a clear MYP Sciences curriculum breakdown of Biology, Chemistry, and Physics, with the concepts, skills, and assessment criteria that actually shape your grades. If you want a broader starting point, begin with the MYP hub on RevisionDojo and then come back here with your next unit in mind.
Quick MYP Sciences checklist (what to learn, what to practise)
Use this checklist to keep MYP revision practical:
-
Know whether your school teaches integrated science (mixed disciplines) or separate Biology/Chemistry/Physics units.
-
Track the key concepts in every unit: Change, Relationships, Systems, Evidence.
-
Practise the four MYP Sciences criteria every week (not just the content).
-
Always include data work: graphs, tables, trends, anomalies, uncertainty.
-
Train “explain” answers: claim + evidence + scientific reasoning.
-
Reflect on impacts: ethics, sustainability, health, technology.
For skill-first revision, the blog post How to Revise for MYP Sciences Without Memorising Everything is a helpful companion.
What MYP Sciences is really designed to do
At its best, MYP Sciences makes you comfortable with uncertainty.
You are not rewarded for having the neatest notebook. You are rewarded for thinking like a scientist: noticing patterns, testing ideas, and communicating what your evidence actually supports. That is why MYP classrooms spend so much time on inquiry, lab planning, and evaluation.
A strong MYP student can do four things repeatedly:
-
Understand scientific ideas well enough to explain them.
-
Apply those ideas in unfamiliar situations.
-
Process and evaluate evidence without panicking.
-
Reflect on consequences, limitations, and ethics.
If you ever feel unsure where you stand, build your practice loop using RevisionDojo’s Questionbank and Study Notes: understand quickly, practise immediately, review mistakes, repeat.
How the MYP Sciences curriculum is structured
Schools have flexibility in how they deliver MYP Sciences:
Integrated science
Biology, Chemistry, and Physics show up inside one thematic unit (for example: “Energy and Sustainability” could combine ecosystems, fuels, and electricity).
Discrete sciences
In later years, many schools separate Biology, Chemistry, and Physics into distinct units or courses. The advantage is clarity. The risk is treating them like three isolated silos.
Either way, the through-line in MYP is the same: concept-based inquiry using the same assessment criteria.
To see how these criteria-focused habits connect to exam success, you can also skim MYP eAssessments: 30-Day Study Plan That Works.
Key concepts and global contexts in MYP Sciences
A good way to recognise MYP questions is that they are secretly concept questions.
Across Biology, Chemistry, and Physics, the core MYP Sciences key concepts often include:
-
Change: what transforms, and what drives the transformation?
-
Relationships: what interacts, and what are the consequences?
-
Systems: what are the parts, boundaries, inputs, outputs?
-
Evidence: what data supports the claim, and how reliable is it?
Then units are often framed with a global context such as scientific and technical innovation, globalization and sustainability, or fairness and development. In practice, that means your “extra paragraph” about implications is not extra at all. In MYP, it is frequently where top bands live.
Biology in MYP: what you study and how it’s assessed
MYP Biology is the science of living systems, but it is also the science of explaining mechanisms.
Common curriculum themes include:
-
Cells and specialized structures
-
Organ systems and homeostasis
-
Genetics, inheritance, variation
-
Ecology, biodiversity, human impact
-
Evolution and adaptation
In MYP Biology, marks tend to appear when you connect levels: cell to tissue, organism to ecosystem, gene to phenotype. A typical high-scoring move is to take one observation and explain it through cause-and-effect steps.
If you want targeted practice, RevisionDojo’s MYP Biology hub is built for this: Questionbank drills, Flashcards for key definitions, and quick notes when you are stuck.
Chemistry in MYP: what you study and how it’s assessed
MYP Chemistry often feels like rules, until you notice the story underneath: matter changes, and those changes can be described, predicted, and tested.
Common curriculum themes include:
-
Atomic structure and periodic patterns
-
Bonding, particle models, structure-property links
-
Reactions: conservation of mass, balancing, energy change
-
Acids, bases, salts, indicators, pH
-
Mixtures, separation, and materials
Chemistry tasks also reward precision: controlled variables, clear units, and careful language about evidence. “The pH decreased” is observation. “The pH decreased because increased hydrogen ion concentration…” is explanation.
For topic-by-topic support, use the MYP Chemistry hub and turn weak areas into small daily sets using the Questionbank.
Physics in MYP: what you study and how it’s assessed
MYP Physics is where your intuition gets tested.
You may “feel” that a heavier object falls faster or that current gets used up. Physics politely challenges those instincts, then asks you to communicate the corrected model under time pressure.
Common curriculum themes include:
-
Forces, motion, Newton’s laws
-
Energy transfers, conservation, efficiency
-
Waves: sound, light, basic properties
-
Electricity and magnetism
-
Space science and the universe
Physics success in MYP often comes down to representation: free-body diagrams, graphs, and clearly labelled reasoning. If you can move between words, equations, and diagrams, you are usually ahead.
MYP Sciences assessment: the four criteria that control your grade
The MYP uses criteria-based assessment, and Sciences typically follows four criteria (each scored 0-8):
Criterion A: Knowing and understanding
You explain scientific knowledge and apply it.
Criterion B: Inquiring and designing
You design investigations, identify variables, and plan a method.
Criterion C: Processing and evaluating
You process data, interpret results, evaluate validity, and suggest improvements.
Criterion D: Reflecting on the impacts of science
You connect science to ethics, environment, society, and limitations.

How to revise for MYP Sciences (without drowning in content)
Here is a simple weekly structure that fits the real demands of MYP Sciences:
-
2 sessions: Questionbank practice sets (mixed difficulty, then review queue)
-
2 sessions: investigation skills (variables, method design, evaluation paragraphs)
-
Daily 10 minutes: Flashcards for definitions, processes, units, and command terms
-
1 session: timed mini mock using Exam Mode + a short error log
RevisionDojo makes that loop easier because everything is connected: Questionbank for targeted practice, Study Notes for quick clarification, Flashcards for active recall, AI Chat to challenge misconceptions, Grading tools to tighten your responses, and Mock Exams to build calm under pressure. When you are doing a longer task, the Coursework Library and Tutors can add examples and human feedback at exactly the moment you would otherwise guess.

Conclusion: make MYP Sciences feel smaller (and more scoreable)
The MYP Sciences curriculum can look like three mountains: Biology, Chemistry, and Physics. But the path up each mountain is surprisingly similar. Learn the concept, practise the skill, interpret the evidence, reflect on the impact.
If you want your next MYP science grade to feel earned instead of accidental, build your routine inside RevisionDojo: start at the MYP hub, use the MYP Biology and Chemistry resources for targeted drills, and make the Questionbank + Study Notes + Flashcards loop your default. The goal is simple: turn “I studied” into “I can apply.” That is the language MYP rewards.
