Physical vs Chemical Changes

Distinguish between physical changes (reversible, no new substances formed) and chemical changes (new substances formed, often irreversible), using conservation of mass to understand both types

How to tell they’ve got it

Tick these off as you see them — no test required.

Try this together

If your child dissolved sugar in tea versus burnt toast in the toaster, could they explain which is a physical change and which is a chemical change — and what test would show that mass is conserved in both cases?

Builds on
Irreversible Changesages 9–11KS3 chemical changes deepens KS2 understanding that burning, rusting and acid reactions form new materials
Reversible Changesages 9–10KS3 physical vs chemical changes extends KS2 reversible vs irreversible changes
Conservation of Massages 10–11KS3 conservation of mass in reactions extends US KS2 evidence that mass is conserved regardless of change type
Atoms, Elements & Compoundsages 11–12Chemical changes involve rearrangement of atoms into new substances — atom/compound concepts are required
The Particle Modelages 11–12The distinction between physical and chemical change is clearest at the particle level

Types of Chemical Reactionages 12–13Types of chemical reaction are specific categories of chemical change — the physical/chemical distinction must come first
