Experimental Procedure
Gather the materials in one spot: this is a nice habit to learn so that you don't have to fumble around for materials during the experiment and so that you can enjoy the whole experience!
Label your three glass jars “White Sugar”, “Brown Sugar”, and “Powdered Sugar.” Set them aside.
Making sure an adult is there to supervise, turn the stove up to medium-high heat and boil the water in the saucepan.
Take two cups of white sugar and carefully pour them into the boiling water, stirring continuously with a wooden spoon to help the sugar complete dissolve. When the solution reaches a rolling boil, it's ready. Note how fast it dissolves. Remove from heat.
Take the glass jar labeled “White Sugar” and carefully pour the solution into the jar. Take a small piece of wax paper and cover the opening of the jar.
Measure a piece of cotton string that is two-thirds the depth of your glass jar. Tie the small weight you chose to one end of the string and tie the other end to the pencil. Carefully dip the string (washer end first) into the solution and let it soak for a couple minutes. Then remove the string, straighten it out, and lay it flat to dry on wax paper for three days (leaving the pencil and the washer attached).
Repeat steps 3–7 for the Brown Sugar and the Powdered Sugar. Important: remember which string went in which solution! Also, be sure not to throw out the sugar solution in the jars. You'll be using it after the three days have passed.
After the three day waiting period for prepping the strings is over, simply suspend the three cotton strings in their respective jars (with the liquid sugar solution in the jars) at room temperature for about one week. Do not touch the strings as movement will disturb the growth process. You should observe, note, and, if possible, take photos of the day-to-day growth of crystals for each jar. A chart is included below as a suggestion.
After one week, you should see at least some sugar crystals. They should be clear and in rather spiky and sharp formations. Compare and contrast the growth, size, and shape of the sugar crystals in all three jars. Are there any differences? Similarities?
