Salt Solution Experiment



Discover more about evaporation and crystallisation with this easy salt solution experiment.





Salt Solution Experiment

You will need

2t salt
small bowl
plastic wrap
warm water
teaspoon




Method

Dissolve the 2 teaspoons of salt in a small bowl of warm water.
Let your children taste a tiny bit to confirm that it is salty.
Cover the bowl with the plastic wrap and set it aside in a warm place for an hour or longer.
After an hour you should see tiny drops of water on the plastic cover.
Remove the plastic carefully and let the children taste the water on the plastic.

Result

The water drops that accumulated on the plastic are not salty as the salt dissolved in the water in the bowl does not evaporate, but remains behind in the bowl.




Variation

Set the bowl aside without the cover for a few days until all the water has evaporated.
Show the children the salt that remains in the bowl. The separation of a dissolved substances from a liquid by means of evaporation is known as crystallisation.
