What is matter? Matter is anything that has mass and occupies space (volume). Matter is everything around you. So rocks, water, air, plants and animals are matter because they all have mass and occupy space. We can classify matter into 3 states of matter i.e. solid, liquid and gas.
Solid
Solids can be hard or soft, heavy or light but all solids have definite mass, definite shape, definite volume and do not flow.
Liquid
Some liquids are coloured while others are not. However, all solids have definite mass, indefinite shape(it takes the shape of the container), definite volume and can flow.
Gas
Some gases have smell while others are odourless, some are coloured while other gases are colorless but all gases have definite mass, indefinite shape, indefinite volume and can flow.
============================================================================
What is matter made up of? Scientists think that matter is made of tiny particles. Kinetic particle theory states that all matter is made up of particles which are constantly moving in all directions.

Here's a song video that might help you remember what we learn today :) I know this ain't Justin Bieber/Taylor Swift/K-Pop's song but it is a catchy song, right? Sing along then and you might as well learn the lyrics to this States of Matter song. ;)

Gas has a definite mass,
indefinite shape
and indefinite volume too.
On heating it expands real large
and it's easily compressible. (2x)
Liquid has a definite mass,
indefinite shape
and definite volume too.
On heating it expands slightly
and has a low compressibility. (2x)
Solid has a definite mass,Read More..
a definite shape
and definite volume too.
On heating it expands real low
and has no compressibility." (2x)
