  1. Properties of matter that describe the way it looks, feels, tastes, etc I. Physical & Chemical Properties of Matter: A. Definition of Physical Property___________ ____________________________________ 1. Examples of Physical Properties:_________ ___________________________________ Density, boiling & melting point, color, odor, texture

  2. Properties that describe how matter might behave under certain conditions B. Definition of Chemical Property___________ ____________________________________ 1. Examples of Chemical Properties:____________________________ ___________________________________ Flammable, corrosive, oxidizer

  3. II. Physical & Chemical Changes of Matter: A. Definition of Physical Change: _____________ ______________________________________ 1. Examples of Physical Changes:___________ ____________________________________ Change in matter w/o changing its chemical composition Phase changes, cutting, bending, dissolving, mixing, stretching

  4. Change in matter that produces a new substance w/ new properties B. Definition of Chemical Change:_____________ ______________________________________ 1. Examples of Chemical Changes:____________ ______________________________________ Tarnish, digest, rot, cook, grow, rust

  5. UNEXPECTEDcolor change 2. Five Clues That a Chemical Change Has Occurred: a) __________________________________ b) __________________________________ c) __________________________________ d) __________________________________ e) __________________________________ ***you DO NOT have to view all five in EVERY chemical reaction, but at least one of the five!!!*** Precipitant – something “falls out” of solution or it gets cloudy Effervescence (bubbling) New odor Change in energy

  6. light sound i. Four ways that energy might be “seen” by us: 1. _________________________ 2. _________________________ 3. _________________________ 4. _________________________ electricity temperature

  7. Watch the demonstrations performed very carefully and in the table below, determine whether a physical change or chemical change occurred.
