This project explores the solubility of sugar in hot versus cold water. Students will measure how quickly sugar cubes dissolve in different temperatures of water, allowing them to learn about the effects of temperature on chemical reactions.
If sugar is added to hot water, then it will dissolve faster than in cold water due to increased molecular movement.

Label the clear containers as 'Hot Water' and 'Cold Water'.
Measure 1 cup of hot water and pour it into the first container.
Measure 1 cup of cold water and pour it into the second container.
Add 5 sugar cubes to the hot water and start timing.
Stir the hot water gently and note the time taken for cubes to dissolve.
Repeat the process for the cold water with another 5 sugar cubes.
Observe and record the time taken for cubes to dissolve in cold water.
Compare the results and analyze how temperature affects sugar solubility.
Create a graph to present your findings.
Discuss the science behind solubility and temperature effects.
The sugar cubes should dissolve faster in hot water compared to cold water, demonstrating how temperature influences solubility. This experiment illustrates the relationship between heat and chemical reactions.
