A question for the whole room
One story to open. A room full of ideas to test.
Ready in three steps
- Open the story.Read and try the first pages together.
- Pause for a prediction.At the story’s question, read its choices aloud. Invite a vote and ask, “What makes you think that?”
- Run it. Watch. Wonder.Choose the class’s prediction, run the experiment, and compare what happened with your guesses.
Different guesses are welcome. The experiment gives everyone something to rethink.
Something to put on paper
A one-page prediction and observation sheet. No answers included.
After the experiment: discussion notes
Talk about what happened
- 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
