00:00:00.000 --> 00:00:03.110
The afternoon sun warmed the meadow.

00:00:03.110 --> 00:00:08.380
A little crow flew past an old tree and stopped in its shade.

00:00:08.380 --> 00:00:12.873
The crow was thirsty, so it looked carefully around.

00:00:12.873 --> 00:00:17.624
Beside the grass stood a pitcher with a narrow opening.

00:00:17.624 --> 00:00:21.685
Inside, a tiny patch of sky shone on the water.

00:00:21.685 --> 00:00:25.745
The crow hopped closer and leaned over the rim.

00:00:25.745 --> 00:00:28.942
There really was water at the bottom!

00:00:28.942 --> 00:00:32.484
But finding water was only the beginning.

00:00:32.484 --> 00:00:37.408
However far the crow stretched, its beak could not reach.

00:00:37.408 --> 00:00:40.000
What exactly needed to change?

00:00:40.000 --> 00:00:45.714
The crow tilted its head, moved around the pitcher and tried again.

00:00:45.714 --> 00:00:49.211
Stretching a little farther did not help.

00:00:49.211 --> 00:00:54.840
It gently pushed the pitcher, but the heavy vessel stayed upright.

00:00:54.840 --> 00:00:56.205
The crow paused.

00:00:56.205 --> 00:01:01.407
Repeating the same action might not bring a different result.

00:01:01.407 --> 00:01:08.486
It looked at the water, then at the narrow opening, and finally down at the ground.

00:01:08.486 --> 00:01:11.898
A few round pebbles lay among the grass.

00:01:11.898 --> 00:01:16.333
What if the crow did not need to reach farther down?

00:01:16.333 --> 00:01:20.000
Could something bring the water up instead?

00:01:20.000 --> 00:01:25.970
The crow picked up a pebble and carefully dropped it into the pitcher.

00:01:25.970 --> 00:01:26.397
Plop!

00:01:26.397 --> 00:01:29.893
The pebble sank and the surface trembled.

00:01:29.893 --> 00:01:31.599
Had the water moved?

00:01:31.599 --> 00:01:33.646
The crow looked closely.

00:01:33.646 --> 00:01:37.910
It seemed a little higher, but still too far away.

00:01:37.910 --> 00:01:45.586
Rather than deciding the idea had failed, the crow added another pebble and watched again.

00:01:45.586 --> 00:01:49.339
Each stone took up space inside the pitcher.

00:01:49.339 --> 00:01:51.983
Some of the water moved upward.

00:01:51.983 --> 00:01:54.115
Now you can try the idea.

00:01:54.115 --> 00:02:00.000
Add a pebble, pause and compare the new water level with the old one.

00:02:00.000 --> 00:02:02.290
One pebble followed another.

00:02:02.290 --> 00:02:08.425
Little by little, the water rose until the crow could finally take a drink.

00:02:08.425 --> 00:02:13.579
It stopped adding stones as soon as the water was within reach.

00:02:13.579 --> 00:02:19.305
The useful idea had grown through noticing, trying and noticing again.

00:02:19.305 --> 00:02:26.585
Our scene uses equal-sized stones and a straight-sided vessel to show the change clearly.

00:02:26.585 --> 00:02:34.029
In a real pitcher, the shape of the container and the size of each stone affect how far the

00:02:34.029 --> 00:02:35.174
surface rises.

00:02:35.174 --> 00:02:40.000
Reset the scene if you want to compare the steps once more.

00:02:40.000 --> 00:02:45.885
The refreshed crow stands in the meadow and gives you a friendly nod.

00:02:45.885 --> 00:02:51.343
You can finish the story here, or begin again on your own table.

00:02:51.343 --> 00:02:59.019
Make the crow and its stage props, arrange the scene and tell the story in your own words.

00:02:59.019 --> 00:03:06.013
For a real observation, ask an adult to help you find a clear household container.

00:03:06.013 --> 00:03:10.362
Mark the water level before adding suitable stones.

00:03:10.362 --> 00:03:17.186
The printed pitcher is a story prop; use the clear container for the experiment.

00:03:17.186 --> 00:03:20.000
What would you like to test next?
