Last week we went to the beach and the kids collected sea water in a bottle for a very simple science experiment.
Back home, they poured water in a bowl and they left it outside, in the sun. They knew water would evaporate and salt would remain in the bowl but they were still fascinated by the view of the salt crystals.
They finally pounded the salt with a mortar and pestle and we are now using it.
A very simple but fascinating experiment. Don’t forget to bring some sea water home next time you go to the beach!
