Why is rain not salty?

We were talking about the water cycle and how the sun evaporates water from the ocean. Then we wondered why the rain wasn't salty. Mrs Jorgensen showed us how to figure it out by doing an experiment.

We dissolved some salt in some water and put it out in the sun to see if it would evaporate.



After lunch we had a look at our plates and look what we found!



The sun evaporated the water but not the salt...
