PHYSICAL & CHEMICAL 
           CHANGES
                               Matter can undergo 2 types of 
                              changes: physical changes and 
                              chemical changes.
                               Do you remember what the main 
     It is important to note  differences are between physical 
     that all matter can go   and chemical changes?
     through changes!
                               Can you give any examples of a 
                              physical change or a chemical 
                              change?
   GOAL FOR TODAY:
    
    While we have a pretty good understanding 
   of the difference between physical and 
   chemical changes, we have to learn a little 
   bit more about how to determine the 
   difference between these two types of 
   changes to matter in everyday situations.

    Experiment #1: Vinegar and Sugar
     
    Experiment #2: Vinegar and Baking Soda
     So what clues can we use to determine if a chemical reaction 
      has taken place?   [Brainstorm & be ready to share out!]

    PHYSICAL CHANGES
   Physical changes DO NOT change 
   the structure of the matter when 
   it is observed or described.
   Structure refers to how the atoms are put 
   together.
