Cross-Curricular Links for The Scientific Method (Wales, Curriculum for Wales)

Cross-curricular work on the scientific method usually amounts to a science teacher mentioning that graphs are also used in geography. That is a token, not a link, and learners spot the difference instantly. The Curriculum for Wales asks for something more substantial across Areas of Learning and Experience, and the scientific method is one of the few topics where a genuine joint task is straightforward to build. Three links, each with a shared task and a shared outcome, work reliably with a Year 8 class.

What separates a link from a mention

A real cross-curricular link has three features. Both subjects give up lesson time, not just one. The learners produce a single piece of work that is assessed against criteria from both subjects. And each subject contributes something the other genuinely lacks, so removing either subject breaks the task.

Apply that test to most cross-curricular planning and it fails on the first point. If the humanities teacher does not lose a lesson to it, it is a science lesson with a costume on.

Link one: expressive arts and the discipline of observation

The scientific method begins with observation, and art teachers have been teaching observation far longer and rather more rigorously than science departments have. The joint task is a controlled comparison: learners record the same object twice, once as a scientific observation with measurement and labelled features, once as a drawing with attention to light and form, and then write about what each method captured that the other could not.

The assessment is shared, and the discussion at the end is genuinely interesting because learners discover that the drawing often notices things the measurement missed. Analysing a Painting – Method, Vocabulary and Exam Training supplies the structured looking method for the art half, which matters because without it the drawing lesson drifts and the comparison has nothing solid on one side.

Link two: humanities and the problem of the uncontrolled variable

Science teaches fair testing with one variable changed. Humanities deals with systems where nothing can be held constant, which is the situation learners will meet in almost every real question they care about. Putting those two ideas beside each other is the most valuable cross-curricular move available on this topic.

The joint task takes a climate question and asks learners to design the experiment they would run if they could control the planet, then to explain what scientists actually do instead: modelling, proxies, and comparison across time. The humanities half brings the human consequences and the policy question; the science half brings the evidence standards. Neither subject can run it alone. Climate Change and the Anthropogenic Greenhouse Effect | Analysis, Impacts & Future Perspectives carries the data and the analytical framing for this, which saves the science department from assembling a dataset that the humanities department can also use.

Link three: science and technology, and the machine that guesses

1. Learners write a hypothesis and a testable prediction. Standard science, ten minutes.
2. They ask an AI tool the same question and record its answer. No evaluation yet, just capture.
3. They interrogate the answer using the scientific method itself. What is the claim, what evidence is offered, what would falsify it, and can the source be checked.
4. They write one paragraph on why a confident answer is not the same as a tested one. This is the outcome assessed by both departments.

This lands harder than any lecture about reliability, because learners have just watched a fluent, plausible answer fail a falsifiability test they applied themselves. AI Literacy & Cybersecurity Activities | Artificial Intelligence, Prompt Engineering & Online Safety | Computer Science Bundle | Grades 7–10 provides the digital competence side so the computing teacher is teaching their own content rather than supervising a science lesson.

Making it survive the timetable

Cross-curricular plans die in the diary, not in the classroom. Fix three things in advance: the fortnight it runs, the single shared success criteria sheet, and who marks what. Two departments, one week each, one jointly assessed outcome. Anything more ambitious than that will not run twice.

Keep the same three links year on year rather than inventing new ones, because the second time round the planning cost is nearly zero and the quality is much higher. The sign that it has worked is small and specific: a learner in a geography lesson in March says the sample was too small, without being prompted, and means it.
