Start with bismillah.

Ask: "What happens when two different kinds of water meet?"

Now listen to the ayah together in the app, with the translation. Ask: "What did Allah let flow?"

Each child keeps one wonder question, for example: "How can two waters touch but stay different?" Younger children can draw theirs.

Find it in the mushaf: Surah Ar-Rahman is surah 55. Find ayah 19. The key words maraja al-bahrayn mean He released the two seas. Where waters of different saltiness, temperature or mud meet, you can sometimes see a line between them. Scientists study how such waters slowly mix. It is a sign to ponder about how Allah orders the oceans.

Fact: Why can water with different amounts of salt form layers?

Ages 5–8: Water layers. With an adult, gently pour salty coloured water and fresh water into a glass and watch.

Ages 9–12: Ocean meeting. Find a place where two seas or a river and a sea meet and describe what happens there.

Finish with: "I found that salty water and fresh water ___."

Talk together:

• What amazes you about the oceans?
• Which name of Allah does this remind you of?
• How can different people meet and stay friends?
• How can we protect seas and rivers?
• What would you like to ask about this ayah?

Make a small plan: "This week, I will keep plastic out of drains, rivers and seas."

• Keep plastic out of water.
• Make water layers.
• Share an ocean meeting place.
• Next time: the next ayah (55:20) says there is a barrier between them. Explore it together!

Action: Keep plastic out of drains, rivers and seas.
