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
