Essay --

Materials: †¢ Yarn (1.5 feet) †¢ Water †¢ Cup †¢ Tablespoon †¢ Small plate †¢ Granulated white sugar (4 cups and 4 tablespoons) †¢ Wax paper †¢ Screws †¢ Popsicle sticks †¢ Marker †¢ Ruler (cm) †¢ 2 mason jars †¢ Bowl †¢ Stove †¢ Measuring cup †¢ Wooden mixing spoon †¢ Pot holders †¢ Paper towels †¢ Notebook †¢ Pencil †¢ Masking tap Procedure: 1. Gather all materials listed. 2. Cut two strings the same lengths that are about 1 centimeter longer than the jar. 3. Fill a cup with water and place the strings in the cup so they can soak for about 5 minutes. 4. While the strings are soaking spread out 1 tablespoon of sugar out on a piece of wax paper and leave one piece of wax paper with nothing on it. 5. Remove the strings and place one string on the wax paper with sugar and roll the string around until it is completely covered with sugar. 6. Set both strings on the blank wax paper, not touching, and allow them to sit overnight. 7. After the sugarcoated string has soaked for twenty-four hours take a screw and tie it to one end of the string. Do the same with the non-sugar coated string. 8. With the other end of the string tie it to a Popsicle sticks. Indicate by using a marker as to which string has the sugar coating on it. 9. Make sure both stings will be long enough so that they can be placed approximately one centimeter from the bottom of the jar. Then set them to the side. 10. The glass jars will need to be preheated. Place them next to the eye of a hot stove. (That is so the glass jars don’t shatter) 11. Next boil water for both of the jars. Once that has boiled pour the water into the warm jars. 12. Now put a cup of water into a pot and bring that to a boil. Turn the heat back down to low. 13. Put three cups of sugar into the boiling water... ...e and organization to how these molecules are aligned. For this process the jar must be left in an undisturbed setting where there is no sunlight beating on it. It takes approximately a week for the sugar crystals to be able to completely grow. As the water molecules evaporate into the air the dissolved sugar molecules will be left behind. The molecules will cling to any solid around them including the sides of the jar and the nail and string placed in the solution. Through the process of nucleation the crystal will begin to form. In conclusion, the result of the experiment is the savory taste of a rock candy. The sugar molecules that are dissolved in the solution, stick together in a repetitive pattern, forming a crystalline solid. Through the process of nucleation students are able to enjoy the sweet taste of sugar molecules bonded together.
