What are materials?
1. Often we think of a fabric-because of the use of the word material.
2. Material or stuff/matter is in fact what EVERY thing is made
up of.
( Materials are used by us humans for all manner of reasons and every thing on this
planet of ours is made from some sort
of Material.)

*****************************************************************************************************
There are 3 main types or categories to describe ANY MATERIAL; Solids, Gases,
Liquids.
Solids : have fixed shapes & volume
-
all their particles are compact and together
Liquids : have no fixed shape, but keeps the same volume, when they flow, they
fill the of the container they
are put in.
(the particles are not tightly packed together as in
solids)
Gases - Will spread out in all directions to fill the
given space -
(The particles making up gases are even more apart than liquids)
Some materials are reversible and some are not
