Crystals can form from a solid, liquid, or gas. Once scientists began studying the fascinating forms of crystals, a bright new science was born that is helping to answer some of the most important questions asked by men in almost every other scientific field today. This young science is called crystallography-the study of crystals. Like most things, crystals are made of molecules. Molecules have different behaviors in different surroundings or circumstances.
All matter comes in one of three forms-solid, liquid, gas.
The original purpose of this experiment was to determine what type of dissolved substance would form the biggest crystal. The results of the experiment were that the rock salt solution grew the biggest crystal formation. During the process of dissolving the different substances, I made some interesting observations. It took about 9 tbs. of rock salt to saturate the water. The rock salt dissolved pretty slowly.
