Conditions of Use · What did you observe when the salt and water
were combined? · How did the water and the salt change when they
were combined in the cup? · How did measurement help you
describe the changes? · The salt went to the bottom of the cup
until you stirred it, then it dissolved. If you put enough salt
in it either took a while to dissolve or it didn’t dissolve at
all. · The salt made the water slightly foggy until it settled
down or got stirred up. The salt “disappeared” or dissolved when
stirred enough. · Measurement helped by telling if the water
weighed more or the water level went up. Article posted January
