What is the nature of science dealing with growing rock candy crystals?

The science behind growing rock candy crystals involves principles of crystallization and supersaturation. When a sugar solution is heated and then allowed to cool, it becomes supersaturated, meaning it holds more sugar than it can normally dissolve. As the solution cools, sugar molecules start to come out of the solution and form solid crystals, which can grow larger over time. This process illustrates key concepts in chemistry, such as solubility, saturation levels, and the physical changes substances undergo.
