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. What are you thinking of?
Asma: A model that shows how rainwater from a school roof can be filtered and stored.
Deepa: That sounds practical. Should we make the water actually flow through the model?
Asma: Yes. We could use transparent tubes so visitors can see each stage.
Deepa: Good idea. Let’s divide the work and test it before the exhibition.
