Make it concrete
Analogy
Rates of reaction is like changing a recipe: the particles, amounts and conditions decide what product you can make.
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
Rates of reaction links to materials, fuels, medicines, pollution and resources. Example: Powdered calcium carbonate reacts faster than marble chips because it has a larger surface area.
Why now: Real examples make the mark-scheme words easier to remember.
Do this: Connect one key word to the example.
