"What's the Matter??"

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.

Examples of solids are apples, books, chairs, soil and flowers.

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.

Examples of liquids are water, oil, alcohol and bromine water.

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.

Examples of gases are air, nitrogen dioxide, ammonia and hydrogen.

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. ;)

p/s: please turn off the sound/music from the game below before you play the video. Thanks and enjoy!

                               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,
                                      a definite shape
                             and definite volume too.

                       and has no compressibility." (2x)
