So if sugar dissolves in water, what will happen if salt is placed in water? What kind of evidence can we gather to support the idea that it will probably dissolve, too?
Students had limited materials and spent Thursday of last week designing their own experiments. We checked back on Tuesday to to collect data and think the long weekend might help to gather more data!

Each group discovered that after a long weekend, the salt remained behind, and even though it looked different than the salt that was initially put in the water, it was still there and didn't "disappear!" So even though we couldn't physically see the salt in the water when we mixed it, we knew it was there after we let the water evaporate!
