What makes the ground shake?
Children watch ripples travel through water, then build towers on a shake tray to see which ones stay standing. They read the opening ayat of Surah Az-Zalzalah and plan small good deeds.
- Time
- About 35 minutes
- Sign in creation
- Earthquakes: the ground we stand on can shake
- Read together
- Az-Zalzala 99:1–2; also Az-Zalzala 99:4, Az-Zalzala 99:7–8
You will need (things at home)
- A clear bowl of water
- Building blocks, plastic cups or sugar cubes
- A tray or baking tin
Two levels
Explorer ★ draws, circles, counts and says (often ages 4–7). Investigator ★★ predicts, tests, records and explains (often ages 7–11). Choose by your child, not by age. Siblings can do the same case at different levels.
The science in plain words
The earth's outer layer is made of huge slabs of rock called plates. They move very slowly, and when they slip suddenly the ground shakes. The shaking travels outwards in waves, like ripples in water. Engineers design buildings with wide bases, strong joints and frames that can bend a little, so they stay standing.
- • Earthquakes happen when rocks underground slip suddenly along a fault, sending out seismic waves. Source: USGS, “What is an earthquake?”.
- • Singapore is far from the plate boundaries but sometimes feels faint tremors from large earthquakes in Sumatra. Source: Meteorological Service Singapore. [still being checked]
We share creation as signs to ponder, not as proof. If your child asks something about the religion that you are unsure of, ask a recognised asatizah together.
Listen for
- The ripples are bigger close to the tap and smaller far away.
- Wide, low towers stay up longer.
- Worry about earthquakes: reassure gently that Singapore rarely feels them.
- Examples of tiny good deeds: let your child name their own.
Another day
- Make a good deeds chart for the week with one box for each day.
- Memorise Surah Az-Zalzalah together in Mini Hafiz.
- Same verse, new me: come back to this case at the end of the month and look at your good deeds chart.

What makes the ground shake?
Try this first
Wow, why?
Put a cup of water on the table. Stand very still and watch it. Now a grown-up gently bumps the table. Did you see the water shiver? What if the whole ground did that?
☐ We tried it!
Read it together · Surah Az-Zalzala 99:1–2
إِذَا زُلْزِلَتِ ٱلْأَرْضُ زِلْزَالَهَا
When the earth is shaken to her (utmost) convulsion, (99:1)
وَأَخْرَجَتِ ٱلْأَرْضُ أَثْقَالَهَا
And the earth throws up her burdens (from within), (99:2)
English: Abdullah Yusuf Ali
Read the ayat together. Listen for what happens to the earth.
My wonder question
Draw something you wonder about. A grown-up can write your question.

What do I notice? How do I know?
ObserveRipples and wobbles
- Put a clear bowl of water in the middle of the table.
- Tap the table gently, then harder.
- Watch the top of the water each time.
⚠ Grown-up help: Keep the bowl away from the table edge and wipe up spills.
Draw the water after a gentle tap and after a hard tap.

Allah made the earth. People build houses. Draw a house you think would stay standing if the ground shook.

TestThe shake tray
- On a tray, build two towers: one tall and thin, one wide and low.
- Slide the tray gently from side to side, then harder.
- Watch which tower falls first.
⚠ Grown-up help: Use light blocks or plastic cups, never glass.
Which tower fell first? Circle it.
