A question for the whole room

One story to open. A room full of ideas to test.

Ready in three steps

  1. Open the story.Read and try the first pages together.
  2. Pause for a prediction.At the story’s question, read its choices aloud. Invite a vote and ask, “What makes you think that?”
  3. 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

  • Why does dividing the same oil into more droplets increase the total boundary?
  • How is a cloudy droplet dispersion different from a dissolved solution?
  • Which part of the story is about molecular preference, and which part is about gravity and density?

Where it shows up in real life

  • Oil-and-vinegar dressing that becomes cloudy when shaken and later returns to two regions
  • A rainbow oil sheen that gathers into patches on a puddle
  • Tiny oil droplets briefly spread through dishwater after a greasy pan is swirled
