Subject

Science

Think like a scientist: observe, measure, test, and explore how the world works - one tiny step at a time.

This track is about how science works rather than any single discipline. It covers materials, living things, energy, forces, light and sound, and then turns to method: measurement, evidence, lab skills, data and how research is actually done.

If you want depth in one field, chemistry, physics and biology have their own tracks. This one suits anyone who wants the shared foundation, or who wants to understand how a scientific claim gets made and tested before diving into a specialism.

This track is about the method rather than any one field. Knowing how a claim gets tested - and what makes a test worth trusting - transfers to every other subject and to a great deal of ordinary life.

Who this track is for

Broad primary and secondary coverage, with the research methods and frontiers units suited to older learners.

How to approach it

The method and evidence units are the most useful part for everyday life
Do this track before or alongside chemistry and physics, not after
Pay attention to measurement and units - most early mistakes come from there

Study guide · 8 min readHow to Learn ScienceThis track is about method rather than any one field, which makes it the most transferable subject on the site. A guide to what a fair test actually requires, why a single study rarely settles anything, and how to tell science from things shaped like it.

What you will be able to do

Design a fair test and say which variables you controlled
Read a graph and say what it does not show
Tell science from something that is dressed as science
Explain why a single study rarely settles anything

The thing people get wrong

That science is a body of facts to be accepted. It is a procedure for finding out which claims survive testing, and its findings are provisional by design - which is a strength that critics regularly present as a weakness.

If you only do 3 units

These three are the spine. Together they cover how a question becomes a test, how results become evidence, and how studies go wrong - which is most of what the subject is for.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
