Make it concrete
Analogy
Density and states is like tracking a system with arrows and numbers: decide what changes, what stays conserved, and what equation describes it.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Why it matters
Real-world use
Density and states links to transport, electricity, imaging, communication, energy and space. Example: A liquid becomes a gas when particles have enough energy to separate.
Why now: Real examples make the mark-scheme words easier to remember.
Do this: Connect one key word to the example.
