In this science fair project you will make a saturated solution of sugar and water in order to grow your own rock candy sugar crystals. You will compare the rate of growth between rock candy that is left to nucleate on its own in the solution, and rock candy that starts off with some assistance. To assist this rock candy, you will jump-start ...
Apr 24, 2017 · Experiment. For each rock candy specimen you will need two cups of boiling water and four cups of sugar. While on medium heat, stir in the sugar until it has completely dissolved and returned to a rolling boil. Remove the saucepan from the heat and pour the sugar mixture into a glass jar. Cut a piece of cotton string about the size of the glass ...

STEP 2. Add four cups of sugar and one cup of water to a saucepan the following day and heat until boiling. Heating the water to dissolve the sugar is the key to making your supersaturated solution. Create the sugar solution: Heat water in a saucepan until it just begins to boil. Remove the saucepan from the heat.
In conclusion, making rock candy can teach us about the amazing world of crystallization. To grow crystals on a string, you first need to soak and dry the string to create small seed crystals for larger ones to form around. Two methods contribute to crystal growth: precipitation and evaporation. Precipitation happens when a supersaturated ...
May 1, 2014 · The procedure is really easy. Dissolve the sugar in the boiling water. You can heat the sugar solution on the stove or in the microwave if you have trouble getting the sugar to dissolve. Add a few drops of food coloring and flavor, if desired. Allow the solution to cool a bit before pouring it into your jar.
Day 1: Seed the string. Cut a string approximately two inch longer than the height of the glass jar. Soak the string in a cup of water for 5 minutes. Use your hand to squeeze the excess water from the string. Roll the string in one tablespoon of sugar on a plate. The string will be coated with sugar.
Sep 18, 2023 · Anchor it to the top of the container somehow. We used a string and a paperclip. Make sure the string isn’t touching the sides of the jar or the bottom of the jar. Put your sugar-water solution somewhere safe to sit for a few days. Watch and wait for your sugar crystals to grow. These are your rock candy crystals.
