Discussion prompts

  • Use the two arrows to explain why a saturated solution is not frozen or inactive.
  • Compare the gentle- and fast-stirring endpoints. What variable changed, and what stayed fixed?
  • Design a fair test of how temperature changes sugar's dissolving limit.

Where it shows up in real life

  • Sugar grains lingering at the bottom of cold lemonade or iced tea
  • A recipe asking you to warm a liquid before dissolving a measured solid
  • Scientists reporting solubility at a specific temperature because the limit depends on conditions
