What is Matter?  What types of matter are there? Can matter change?
 

Matter is anything that has mass and takes up space. EVERYTHING is made up of matter, no matter what it is.
 
 
The Three States of Matter
 
Matter can be in 3 different states: solid, liquid, or gas.
 
Solid: matter that has definite shape and volume
Liquid: a form of matter that flows, has a fixed volume, and takes the shape of its container
Gas: a form of matter that takes the shape and volume of its container
 
 
What's A Substance?
 
Substance: matter that has a uniform and definite composition
 
Studying the physical properties of a substance can help you identify the substance. Physical properties are things like color, smell, taste, texture, density, melting point, and boiling point.
 
Ways Matter Can Change
 
Matter can go through 2 types of change: physical and chemical
 
Physical Changes
               A physical change changes a material without altering the chemical composition.
              Examples
  • Breaking 
  • Chopping 
  • Bending
  • Boiling
  • Freezing
  • Cutting
  • Crushing         

Chemical Changes 

             A chemical change, or reaction, one or more substances change into new substances. The composition of the substance is changed.

            Examples:

  • rotting
  • rusting
  • burning
  • exploding
  • decomposing
