Salt of the Earth

Our latest activity is 'Salt of the Earth; who can make the biggest salt crystal?'
This activity provides a practical example of chemistry in action. Your pupils may know that crystals of salt (sodium chloride) form when salty water evaporates, but do they know how to grow a big crystal? Let them find out with this Earthlearningidea.
Please try this out and send us your thoughts and comments - - better still; let your pupils send us their thoughts and comments.
