9-17-13 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.

Chemical Properties Closing Study Jams

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
Slide 5
Opening- Which cookie is yours? Materials: Cookies in a bag
Triple Beam Balance Ruler Pencils
Slide 6
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!
Slide 7
Procedure cont. Place your napkin over the cookie. I will call
on several students to describe their cookie- when 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)
Slide 8
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?
Slide 9
Matter All matter has 2 types of properties: Physical
properties and chemical properties.
Slide 10
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
matters identity.
Slide 11
Malleability The ability of a substance to be rolled or pounded
into thin sheets. The ability of a substance to be rolled or
pounded into thin sheets.
Slide 12
Physical State 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.
Slide 13
Mass Mass is the amount of matter in an object. Mass is
measured with a balance. Mass is the amount of matter in an object.
Mass is measured with a balance. Mass is not the same as weight.
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. Weight is a
result of the pull of gravity on an object and is measured with a
scale.
Slide 14
Density Sinking & Floating Density Sinking & Floating
Weight doesnt determine if an object will sink or float. Weight
doesnt 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. The volume of an object and how much stuff (matter) is
in the object will determine the density.
Slide 15
Solubility in Water Ability of a substance to dissolve in
another substance 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. 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.
Slide 16
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.
Slide 17
Ductility The ability of a substance to be pulled into a wire
The ability of a substance to be pulled into a wire

Slide 19
Chemical Properties 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
Slide 20
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
Slide 21
Combustibility The ability to blow up
Slide 22
Flammability The ability to burn
