Being absorbent can be a property of some materials.
If a material is absorbent it soaks up something, often liquid such as water.
Some materials are absorbent and this makes them suitable for certain uses.
Scientists test materials to find out which are absorbent and which are not.

In comparing the extent of a given property in two materials, children may rely purely on observation rather than on active testing.
