What is Matter?
• Amount of stuff that is in an object
• Anything that has mass and takes up space
• Made up of atoms and molecules• This is why things take up space
• 3 common states of matter:• 1. solid• 2. liquid• 3. gas

What properties are used to describe matter?
• Physical property: something about matter (object) that can be observed or measured• Ex: color, state of matter, melting point, boiling point, mass,
volume, density, etc.
• Chemical property: may only be observed if you change the chemical identity of an object• Ex: Iron is able to form rust when it combines with oxygen.
Ability to rust is a chemical property of iron.

What are physical changes?
• When a substance changes state of matter, but it does not change chemically
• The state of matter changes, but the substance is still the same • Ex: water freezing into ice• Cutting a piece of wood into
smaller pieces• Tearing up a piece of paper

What are chemical changes?
• When a substance changes into something new
• This occurs due to heating, chemical reaction, etc.
• You can tell a chemical changes has occurred if the density, melting point, or freezing point of the original substance changes
• Most of the time, a chemical change can be seen• PRECIPITATE may form: solid that
forms and settles out of a liquid

Hold Up… Wait a Minute…
• Questions to think about:• Is it possible to understand something that we cannot see?• What kind of perspective (point of view) can give you an in
depth understanding of matter?
