Today's Lesson: Properties

We learned about chemical and physical properties today.

Chemical Property is the characteristic that describes the ability of a substance to change to a different substance.

Some examples of this property are:
rusting (aka: oxidizing), heat, flammability, and digesting of food.
  
         (fire)                   (rusting)

Physical Property is a characteristic of a substance that can change without the substances becoming a different substance.

Some examples of this are:
smell, color, odor, volume, state (gas, liquid, or solid), boiling point, and melting point
   
           (color)                          (gas)

[ Taste is also considered a physical property but isn't used in chemistry. You don't want to place chemicals into your body what so ever, they could be very dangerous]
