The Ability of Materials to Absorb Water

 
  • Each material in our environment has its own properties and ability. 
 

Water Absorbent Object, Non-Water Absorbent Object

 
  • Water absorbent objects are objects that can absorb water. 
 
Examples of absorbent objects:-
 
  • Non-water absorbent objects are objects that cannot absorb water. 
 
Examples of non-absorbent objects:-

 
 

The Importance of Water Absorbent Materials

 
  • Water absorbent objects have small pores that can absorb water. 
 
  • As an example, woods can absorb water. Hence, objects that are made up of wood like paper and tissue can absorb water. 
 
  • Examples of objects that are made up of water-absorbent materials and their uses:-
 
Materials Objects Uses of the objects
Cotton  Shirt, pants and towel  Uses to cover our body and dry our body.
Wood Paper Absorb ink when writing
Animal's fur Paintbrush  Can absorb oil paint and water paint
 
 

The Importance of Non-water Absorbent Materials 

 
  • There are multiples materials that are non-water absorbents such as rubber, glass, metals and plastic. 
 
  • These non-water absorbents materials can be used to make multiples objects and appliances. 
 
  • Examples of objects that made up of water-absorbent materials and their uses:-
 
Materials  Objects  Uses of the objects
Plastic Umbrella and raincoat  Protect us from the rain
Rubber Gloves and shoe  Protect our body parts from water or harmful things
Glass Window  Protect the house from the rain
