The four criteria
Knowing and understanding
Explaining scientific knowledge, applying it to familiar and unfamiliar problems, and making scientifically supported judgments. Assessed through tests or exams.
Inquiring and designing
Identifying a testable question, formulating and explaining a hypothesis, and designing a logical, safe and complete method for an open-ended investigation.
Processing and evaluating
Presenting and interpreting collected data, evaluating the validity of a hypothesis and method, and proposing realistic improvements or extensions.
Reflecting on the impacts of science
Explaining how science is applied to a real problem, discussing its moral, ethical, social, economic, political, cultural or environmental implications, and correctly documenting sources.
Aims
MYP sciences aims to encourage and enable students to:
- Understand and appreciate science and its implications
- Consider science as a human endeavour with benefits and limitations
- Cultivate analytical, inquiring and flexible minds that pose questions, solve problems, construct explanations and judge arguments
- Develop skills to design and perform investigations, evaluate evidence and reach conclusions
- Build an awareness of the need to collaborate and communicate effectively
- Develop sensitivity toward the living and non-living environment
- Reflect on learning experiences and make informed choices
How demand increases across the programme
| Objective | Year 1 | Year 3 | Year 5 |
|---|---|---|---|
| A: Knowing | outline | describe | explain |
| B: Inquiring | outline a prediction | outline a hypothesis | formulate a hypothesis |
| C: Processing | discuss validity | discuss validity | evaluate validity |
| D: Reflecting | summarize impacts | discuss & analyse impacts | discuss & evaluate impacts |
Year 1 problems are also restricted to familiar situations; by Year 5, students are expected to apply knowledge and understanding to unfamiliar situations as well.
Interdisciplinary learning
Schools must engage students in at least one collaboratively planned interdisciplinary unit per year. In sciences, common pairings include using mathematics to interpret and present data, applying quantitative analysis to arts or design projects, and investigating material properties for design and technology projects.
Study tips
- 1Treat Criterion B (Inquiring and Designing) as a habit, not a one-off skill — practice turning a vague curiosity into one clearly testable question with identified variables before touching any equipment.
- 2For Criterion C, always tie your interpretation of data back to scientific reasoning, not just a description of the trend — ‘the results show X, which happens because Y’ scores higher than ‘the results show X.’
- 3For Criterion D, pick one factor (moral, ethical, social, economic, political, cultural or environmental) and go deep rather than skimming several — depth on one is what the top band actually rewards.
- 4Keep a running list of sources as you research, in whatever citation style your school requires — Criterion D explicitly assesses documentation of others’ work.
- 5If your school offers optional eAssessment, ask your teacher early which Year 5 criteria map onto the on-screen exam format, since it draws only from Criterion A and B-style tasks.
