A dialogue is not two people taking turns to be pleasant. It must move: a proposal, a doubt, a disagreement, and a decision reached by the end. Keep the tone informal — these are classmates — and use the stage directions in brackets to carry the feelings the words do not say.
(The Science Club room, Friday afternoon. Asma is sitting with a notebook. Deepa comes in with her bag still on one shoulder.)
Deepa: Hi Asma! Our Science teacher mentioned that you have a wonderful idea for the Science Fair project.
Asma: (hesitatingly) Yes, I do. But I'm not sure if it is good enough.
Deepa: (encouragingly) Don't worry. Every idea sounds silly until somebody says it aloud. Go on.
Asma: Er… you know the water cooler outside the staff room? It runs the whole day and the water is still warm by two o'clock. I want to make a cooling box that works without electricity — just a clay pot inside a bigger clay pot, with wet sand between them.
Deepa: (sitting down) A matka inside a matka? Asma, that's not an invention, that's my grandmother's kitchen!
Asma: (quietly) That is exactly why I wasn't going to tell anyone.
Deepa: No, wait — I'm not saying it's bad. I'm saying nobody will look at it twice unless we can prove something. Can we?
Asma: That's the part I've worked out. We put a thermometer inside the pot and one in the open air, and we take readings every hour for three days. If the inside stays six or seven degrees cooler, we have a graph — and a graph is not a kitchen.
Deepa: (interested now) Uff, that changes everything. But three days of readings? We have the Hindi test on Wednesday.
Asma: We split it. You take the morning readings before assembly, I take the afternoon ones. Sunday we both come for an hour.
Deepa: Hmm. I still think we should do the solar cooker instead. It looks impressive, and Nikhil's group did one last year and won.
Asma: (firmly) That's the reason not to do it. The judges have seen twenty solar cookers. They have never seen someone measure a matka.
Deepa: (laughing) All right, all right. You win. But I'm designing the chart, because your handwriting is a crime.
Asma: (grinning) Deal. I'll ask my mother for the two pots today.
Deepa: And I'll ask Sir for two thermometers. Same place, Monday, seven-fifteen?
Asma: Seven-fifteen.
- Setting is given in one line of stage direction: place, day, who is doing what.
- Tone is informal throughout — contractions, an interruption, a joke about handwriting.
- There is a real disagreement (matka versus solar cooker) and it is settled by an argument, not by one girl giving in politely. Without a disagreement a dialogue has no reason to exist.
- Brackets carry emotion and action: (hesitatingly), (sitting down), (firmly), (grinning).
- Fillers — “Er…”, “Uff”, “Hmm” — are used sparingly, only where a real speaker would pause.
- It ends with a decision and a next step: who brings what, and when they meet.
