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
- A radio wave can change two things: its height and its spacing. Predict which one a storm messes up most, then add the storm and watch.
- AM hides the song in the height, FM hides it in the spacing. Before running it, guess which survives a big storm and say why.
- Predict first: if AM travels hundreds of miles at night but crackles, and FM is clear but short-range, which would you build for a whole state? Defend your pick.
Where it shows up in real life
- Static crackle on a car's AM station during a thunderstorm while FM stays crisp
- A radio dropping into hiss when you drive through a tunnel or parking garage
- Catching a faraway AM station late at night that you can't hear in the daytime
