TODAY’S LESSON: WHAT
IS CHEMISTRY?
 Chemistry is the
study of
composition of
substances and
the changes it
undergoes.
 Chemistry is the
study of matter.
THE POWER OF
OBSERVATION
 One of the most
important skills of
a chemist!
 It allows us to
detect chemical
and physical
changes.
 The heart of
chemistry.
CHEMICAL AND PHYSICAL
CHANGES
 Physical Change
 Alters a given
material without
changing its
composition.
 Cutting, grinding,
bending, boiling,
freezing, crushing.
 Chemical Change
 A change that
produces a new
substance or
substances.
 Rusting, tarnishing,
milk souring, baking
cookies, a gas is
released, heat is
released or absorbed.
WHAT IS THE DIFFERENCE BETWEEN
AN OBSERVATION AND A
CONCLUSION?
 Observations are what you see,
hear, feel, and what you smell from
your environment.
 Using your senses, detect changes.
 Conclusions are based upon your
observations.
 They try to explain why you observed
the phenomena you did.
