During our Monday Teams meeting, I showed you some salt crystals that I have made in the classroom.
Would you like to grow some too? This is a fun way to separate water and salt when salt has been dissolved in the water using evaporation.
This Using evaporation to grow crystals sheet gives some instructions.
Extra tips to be successful and safe:
- check with your parents
- use very warm water from your hot tap instead of a kettle
- keep adding and dissolving salt – you will be able to dissolve more than you think!
- add a few drops of food colouring (if you have any in the kitchen cupboard)
- leave the glass jar or plastic cup in a warm place like an airing cupboard or above a radiator
Happy crystal growing!
