Read the following Paragraph. What is the main
idea? Find the sentence that is incorrect and
correct it!!
Look around the classroom. Everything, from the
clothes you are wearing to the air you breathe is
matter. Matter is very important. Matter makes
up everything including living things like plants
and people. It also makes non-living things such
as tables and chairs. Things as big as an elephant
or as tiny as a grain of sand on a beach are matter.
Everything is matter and matter comes in three
different states: solid, liquid, gas, and plasma.
That means that everything is either a solid, a
liquid, or a gas. Each state has properties.

MYP Unit Question: How can such a small thing impact our environment in
such a big way?
Area Of Interaction: Environment
Learner Profile: Inquirer, Communicators
Essential Question: How is matter described by physical and chemical
properties and how does it change?
Standard: Students will examine the scientific view of the nature of
matter.
d. Distinguish between physical and chemical properties of matter as
physical (i.e., density, melting point, boiling point) or chemical (i.e.,
reactivity, combustibility).
Learning Target:
Today I am learning how to describe matter using physical or chemical
properties. This is important because matters unique properties make it
easier for me tell object apart..
Homework: Make Cornell Notes from your Foldable
OpeningWhich cookie is yours?
Materials:
• Cookies in a bag
• Triple Beam Balance
• Ruler
• Pencils
Procedure
• Observe and list 10 different descriptions of
your cookie including MASS.
• Do not take the cookie out of the bag!
• Do not change the cookie in any way!
• Draw and color your cookie. Be detailed!
Procedure cont.
• Place your napkin over the cookie.
• I will call on several students to describe their cookiewhen you think you know which one they are
describing- raise your hand.
• As we are making our foldables you may eat your
cookie! (please be mindful of our little (not so little)
friends)
Conclusions
• What kinds of observations/descriptions were the
most helpful in identifying the cookies?
• Which were not useful and why?
• Thinking about your cookies “physical properties”,
list 5 physical properties of your cookie.
• What is another way that we could have tested your
cookies physical property without changing
anything about your cookie?
Matter
All matter has 2
types of
properties:
Physical
properties and
chemical
properties.
Work Session- Foldable
• Physical properties are used to
identify, describe and classify
matter.
• Physical Property- a property that
can be observed or measured
without changing the matter’s
identity.
Malleability
• The ability of a substance to be
rolled or pounded into thin
sheets.
Physical State
• The physical form in which a
substance exists.
• Three forms that we find on earth:
liquid, solid, or gas
• Temperature changes are involved
with changes in state.
Mass
• Mass is the amount of matter in
an object. Mass is measured with
a balance.
• Mass is not the same as weight.
• Weight is a result of the pull of
gravity on an object and is
measured with a scale.
Density
Sinking & Floating
• Weight doesn’t determine if an
object will sink or float.
• The volume of an object and how
much “stuff” (matter) is in the
object will determine the density.
Solubility in Water
• Ability of a substance to dissolve
in another substance
• A liquid, solid, or gas can be
dissolved in water. Examples may
include lemon juice in water,
sugar in tea, and the carbonation
in a soda.
Conductivity
• Some materials allow thermal
(heat) or electrical energy to flow
through them easily.
• Conductivity is the rate at which a
substance transfers heat.
• Materials which easily transfer heat
are called conductors.
Ductility
• The ability of a substance to
be pulled into a wire
Other physical
Properties
Hardness
Texture
Color
Odor
Taste
Temperature
Chemical Properties
• Chemical properties are characteristics involved
when a substance interacts with another substance
to change its chemical make-up.
• A Chemical property is a characteristic of a substance
that can only be observed by changing it into a
different substance
Reactivity
• How likely the atoms of a substance
are to form bonds with other
substances (HUGH???)
• Simply put – reactivity describes
matters "potential" to undergo
some chemical change or reaction
when combined with something else

Combustibility
• The ability to blow up
Flammability
• The ability to burn
Chemical Properties
Flammability
Rusting
Creating gas
bubbles
Creating a
new chemical
product
Reactivity
pH
