1. Absorb-to take in (something,such as a
liquid) in a natural or gradual way
Porous- having small holes that allow air
or liquid to pass through
Non-Porous-materials that do not allow
air or liquid to pass through

2. •There are different materials in our environment that
can be classified according to their ability to absorb
water.
• Some materials can absorb water more than others.
•Cotton is very porous,which makes it a natural absorber
of water
•Plastics as a non-porous material, does not allow water
to pass through
•Porous materials are materials having small holes that
allow air or liquid to pass through.

3. •When materials get wet there were changes
in its characteristics.
•Paper bag easily get wet than plastic bag, a
non porous material which does not allow
water to pass through.
•We need to use raincoats to prevent us from
getting wet. Plastic does not allow water to
pass through.
