Start with bismillah.

Ask: "Have you ever tasted sea water by accident?"

Watch the Wonder World video Fresh Water Meets Sea Water.

Now listen to the ayah together in the app, with the translation. Ask: "What comes from both kinds of water?"

Each child keeps one wonder question, for example: "Why is the sea salty but rivers are not?" Younger children can draw theirs.

Find it in the mushaf: Surah Fatir is surah 35. Find ayah 12. The key words 'adhbun furat mean sweet and fresh. Rivers carry sweet water, while the sea is salty. Yet both give fish to eat, and pearls and coral to wear. Ships cut through the waves carrying goods. These are signs to ponder and reasons to give thanks.

Fact: How do oysters make pearls?

Ages 5–8: Taste test. With an adult, taste a drop of plain water and a drop of salty water and describe the difference.

Ages 9–12: Float test. See whether an egg floats better in fresh water or salty water, and explain why.

Finish with: "I found that oysters make pearls by ___."

Talk together:

• Why are both kinds of water gifts?
• Which name of Allah does this remind you of?
• What food from the water do you like?
• How can we keep rivers and seas clean?
• What would you like to ask about this ayah?

Make a small plan: "This week, I will avoid wasting water and thank Allah for every drink."

• Thank Allah for water.
• Do a taste test.
• Share your float test.
• Next time: the next ayah (35:13) shows night and day blending. Explore it together!

Action: Avoid wasting water and thank Allah for every drink.
