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
- Predict before we test: if you squeeze a gas, does it get hotter or colder — and what about letting it expand?
- Predict: on a freezing 0° day, could a machine still find heat outside to pull into the house?
- Predict: is it cheaper to MAKE heat from scratch, or to CARRY heat that's already there?
Where it shows up in real life
- The warm air blowing off the outdoor AC box or from behind the refrigerator
- A car's air conditioner and the little puddle of water it drips under a parked car in summer
- Heat-pump water heaters and home heat pumps that both cool in summer and warm in winter
