Purpose:
The purpose of this lab is to create crystals of hard rock candy from a supersaturated solution.
Material List: hot plate triple beam balance
400 mL beaker clean glass jar
Cup
String
3 cups of sugar
1 cup of water beaker tongs food coloring (optional) glass stirring rod
Procedure:
1.First collect materials listed
2.Use the triple beam balance scale to measure the mass of the cup and the jar
3.Mix sugar and water in a beaker
4.Place the mixed solution onto a hotplate
5.Stir the solution
6.After stirring measure the temperature of the solution
7.Create a cross with

As the temperature rises the average velocity for the particles increases. This lets them move from one position to another easily. The change in solubility with change in temperature is sometimes used to create solutions with more solute dissolved than predicted by the solubility of the substance.
Rock candy is made from a supersaturated solution of sugar. A supersaturated solution is one that holds more than the maximum amount of solution at a given temperature. You can make it by adding more sugar to water than can dissolve at the current room temperature. Next you heat the mixture until the saturation point has been increased enough to allow all of the sugar to dissolve. Putting a string in the hot solution, and leaving the rock candy out in room temperature for a while to cool. The solution remains supersaturated for a very long time.
Sugar molecules, which are relatively large, are slow to find the proper positions for crystal formation. Meanwhile, collisions with water molecules keep knocking them apart. Eventually, however, solid begins to form on the protected, irregular surfaces of the suspended string. Dissolved sugar molecules
