Changes & Separation Vocabulary
Use process vocabulary for changes of state and material separation — dissolve, solution, soluble, insoluble, evaporate, condense, melt, freeze, filter, sieve, mixture, separate — and understand precisely what each term describes, including the important distinction between dissolving and melting
Lesson
Set out your lesson
“Changes & Separation Vocabulary means using words for changes of state and separating mixtures. We will practise once together, then check a fresh example.”
Bring to the table
- Vocabulary cards: dissolve, evaporate, melt, freeze, filter, mixture
- Cup of water, spoon of sugar or salt (adult), coffee filter or sieve
Extra for the adult
Worked example. Sugar can dissolve in water to make a solution. Water can evaporate. A filter can separate some mixtures.
Optional challenge. For Changes & Separation Vocabulary, add filter or evaporate.
What to notice. Keep one parent note: process words matched; support used. This session samples materials vocabulary, not mastery of chemistry.

Check understanding
- Distinguish 'dissolve' from 'melt' correctly in context and explain the difference
- Use 'soluble' and 'insoluble' accurately when describing whether a material dissolves in water
- Explain the difference between evaporation and condensation using the correct terms
“If your child stirs sugar into tea, can they explain whether the sugar dissolved or melted — and tell you those are different things?”
