One story to open. A room full of ideas to test.
Ready in three steps

- 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
- Predict a new case: if an outside target starts on one side, which retinal side receives it after the light paths cross?
- What must be missing at a nerve-cable doorway for light there to make no visual message?
- How could filling-in help in ordinary life and also occasionally fool you?
Where it shows up in real life
- Covering one eye while looking through a toy telescope
- An eye doctor mapping the optic disc and visual field
