A summer marsh can look like scattered lanterns with no conductor. The story asks how shared timing could grow from repeated interactions, then makes the model conditions visible instead of treating 'no leader' as magic.
Talk about it

- At the hinge, list every matched condition and make a reasoned prediction among all three choices.
- After watching, separate what the exact seeded model showed from what the story says about real fireflies.
