Where are we going with this?
The point of this deck is to give the background information and examples so that we can differentiate between substances (pure and mixtures) based on physical and chemical properties.

What is matter?
Not what is the matter… That's a different question.

Matter is all the physical stuff that makes up the universe.

If it is made of matter, it is a noun. However, not all nouns are made of matter, so… Within the common vernacular, if you can see, smell, taste, or touch it, it is matter.

Seems simple enough? Let's formalize this a little, then:

In the universe, matter includes any physical substance that possesses rest mass. Matter does not (even though they are things in the universe) include:

mind, thoughts, spirit, emotions
