What Things Absorb Water?

We experimented on what things absorb water?

I laid out several type of materials on the table for Timmy to explore.
Newspaper, tissue paper, kitchen towel, plastic, sticker paper, magazine, carton, and milk carton.

Then we added drops of water onto the material, and saw which ones absorbed water.

We found out that newspaper, tissue, carton, kitchen towel absorbed water.
Milk carton, magazine, plastic, sticker paper didn't.

Why milk carton, which was made of carton did not absorbed water?
While carton did?
Because there was the plastic lining.

Then Timmy filled the milk carton with water and he water the plant. Hehehe...

Afterwards, we left the wet newspaper under the sun to let it dry.
Where did all the water go?

Then we talked about the water cycle, where water comes from the mountain, down the river, into house piping, into the drain, back to the river, to the sea and water evaporates, becomes cloud, then comes down as rain. And the cycle begins again...
