What explains the result?
Warm water often dissolves the coating faster, but moving water and plate tilt also shape the pattern.

INVESTIGATION QUESTIONHow does water temperature change color spread?
● ILLUSTRATIVE SCIENCE MODEL
ENGLISH CAPTIONS
Arrange the candy ring. Even spacing makes the color fronts easier to compare.
0.0 / 3.0 s
Where does this matter?
Dissolving and fluid flow matter in drinks, cooking, and environmental transport.
What should you keep in mind?
This is not pure diffusion: pouring currents, convection, plate tilt, and candy spacing affect the rings.

Build a candy ring, add a measured volume of water, and compare how temperature changes coating dissolution and color movement.

Trial notebook
No condition recorded yet. Test at least two temperatures; repeat each run before deciding whether a trend is consistent.
INTERPRET WITH CARE: Displayed seconds are illustrative model values, not experimental measurements. Warm water usually dissolves the sugar-and-dye coating faster, but the visible pattern is not pure diffusion. Water currents, plate tilt, exact pour, dye concentration and candy placement can change the color-front shape.
