Yes, As you know sea water is salty. When the sea water is evaporated we can get salt. Salt that is produced by the evaporation of sea water contains other elements > Let¡¯s do it right now.. Put some salt into water and stir it. what happened? It disappeared, where did it go? Don¡¯t worry. Salt dissolves in water. It means salt is still in the water. it is just invisible now.. but how can we get salt again? Evaporation!! Good idea!! let¡¯s boil away. Look! It appeared! > > ¿äÁò¿¡´Â ³¯ÀÌ ´õ¿ì´Ï ¹Û¿¡ ³» ³õ°í Áõ¹ßÇÏ´Â °ÍÀ» º¸´Â °Íµµ ÁÁÀ» °Í °°³×¿ä. >
