Teacher tip
Fizz a tablet in water or show toast next to bread: a chemical change makes something new.
How to use it
- Stir salt, sand and sugar into clear cups of water before the sheet.
- Show a physical change (cutting paper) and a chemical one (a fizzing tablet).
- Let partners compare answers and settle any differences with a book or a video.
Watch for
Dissolved doesn’t mean gone. The salt is still in the water.
Talk about it
- Can this change be undone?
- What evidence helped you choose your answer?
