Chemistry and Matter

VIEWS: 0 PAGES: 6

									Chemistry and
   Matter
 Chapter 1 section 2
Objectives:
   Compare and Contrast mass and weight.
   Explain why chemist are interested in a
    submicroscopic description of matter.
   Identify the area of emphasis for various
    branches of chemistry
        Mass              vs.        Weight
   A measurement that        Is a measure not only
    reflects the AMOUNT        of the amount of
    of matter.                 matter but also the
   * remember that            effect of the Earth’s
    matter is anything that    gravitational pull on
    has mass and takes         the matter.
    up space…*                Weight = (acceleration
                               due to gravity) x mass
Question:
   Where would I weight more… the top of
    mountain, a valley below sea level, or here
    in Cleveland, TN ?
   When does mass change due to the
    location of the matter?
Models
   Defined as a visual, verbal, or
    mathematical explanation of experimental
    data.
   Give examples of when, where, and how
    models are used in everyday life…
Branches of Chemistry to know…
   Look at table 1.1 on page 11
   Take a moment and read over the table,
    then list how each of those branches of
    chemistry has affected your life with in the
    last 72 hours.
   Observation Activity
