The pieces were clearer and sharper looking than the original rock salt. 2. Describe the initial observations made when several drops of water were added to few particles rock salt and the observations made several minutes later. Initially, the rock salt partially dissolved in the drops of water. After several minutes, the salt was more dissolved, but had not completely dissolved. There were very fine grains of salt that were visible at the base of the water bubble that hadn’t dissolved. 3. In light of these observations, what can be concluded about salt? Salt can be broken down and dissolved by water, but not in high concentrations. C. Do all the grains of sand look like they are made out of the same material? No. 1. Propose a hypothesis to explain the observed appearance of sand. Sand is a conglomeration of rocks and stones that have been broken down into sediments. 2. Describe what was initially observed when several drops of water were added to several grains of sand and the observations made several minutes later. Initially, when water was added to sand, the sand was unchanged. After several minutes, the sand continued to appear unchanged. 3. In light of these observations, what can be concluded about sand? Sand cannot be dissolved into water. D. The water and oil acted differently on the reaction surface. Propose a hypothesis that explains the different behavior of
