Physical Properties & Physical Changes
Page
#

Every element on the
Periodic Table has it’s own
set of physical & chemical
properties, that is what
makes their “personalities”
unique and constant!!!
Property vs. Change
What is the difference between
a property and a change?
Discuss with your table partner
and come up with an answer to
write in the box…
What is a Physical Property?
 A characteristic of
an element or
substance that can
be observed or
measured without
changing its
identity or
structure.
 Use your 5 senses
OR scientific
measurements to
describe or
measure…
What is a Physical Change?
 A change that takes
place without
changing the identity
or structure of the
element or substance
 EXAMPLES:
 Dissolving
 Phase change
 Changing shape
What are some other
examples?
 Mass per volume of a
DENSITY
material, or how much
“stuff” is packed
together in specific
area.
 Formula to calculate
density:
 Density = mass/volume
SOLUBILITY
 A measure of how
much of a
substance dissolves
in a given amount
of another
substance.
Solubility Side Note:
Solvent = the substance that does
the dissolving
Solute = the substance that
dissolves
Insoluble = doesn’t dissolve
BOILING
POINT
 The temperature
at which a liquid
changes to a gas.
MELTING
POINT
 The temperature at
which a solid
changes to a liquid.
MAGNETISM
 A force of attraction
or repulsion that
exists between like
and unlike poles.
MALLEABILITY
 The ability to be
hammered, shaped,
or rolled into thing
sheets. Most metals
are malleable.
Malleability Side Note:
 You may also hear the
word ductile or ductility
 Ductility = the ability of
a material to be
stretched into a wire
 What about Brittle?
CONDUCTIVTY
 The ability of a material
or substance that
allows electricity or
heat to flow through it
easily. Most metals are
good conductors.
SPECIFIC
HEAT
 The amount of
energy (usually
heat) needed to
raise 1 gram of a
substance by 1
degree Celsius
(1C).
Log in, and put your note guide away!
Physical Property &
Physical Change Ticket Out the Door
 Rip out a piece of notebook paper and put your name
on it.
 Think of any object…something you see in the room or
in your house and write it at the top of your paper.
 List 5 physical properties that that item has
 Describe in 2 sentences something you could do to
cause a physical change to your object and why it
qualifies as a physical change
 Read what you have to your table partner…are you both
correct?
 Put it in the basket on your way out the door!
WARM UP:
 Write your homework – leave it out to be stamped.
 QUIZ on physical & chemical properties/changes in 2
classes...yes, it will be formal!
 Get your Blendspace Note Guide out to be checked!
 What questions do you have about physical or chemical
properties/changes?

What is a Chemical
Property?
 A characteristic that
gives a substance the
ability to change into a
new substance…BUT
the chemical change
has to be happening to
see the chemical
properties!
CHEMICAL
REACTIVITY
 The ability of a
material or
substance to
react with
another material
or substance and
form something
entirely different.
TOXICITY
 The degree to
which a chemical
can harm an
organism.
FLAMMABILITY
 The ability of a
material or
substance to burn
or start on fire
easily.
REACTIVITY
WITH OXYGEN
 The ability of a
material or
substance (usually
metals) to react with
oxygen and cause
them to rust,
corrode, tarnish, or
combust.
What is a Chemical Change?
 A change that results in
the production of a new
substance and cannot be
reversed.
 EXAMPLES:
 Burning
 Rusting
 Cooking
What are some other
examples?

Be sure to write
one other original
example!
Evidence of a Chemical
Change/Reaction:
 Color changes – color appears or
disappears
 Temperature changes
 Gas/gas bubbles produced
 Fire/flame/light produced or
explosion
 Precipitate is formed – a solid or solid
particles forms out of 2 liquids
Physical Vs. Chemical
 Do some research and make a list of 5 ORIGINAL
examples of physical changes and 5 ORIGINAL
examples of chemical changes that we have not
discussed in class!

Labs to Examine Chemical
Changes
Mini Lab 1: Teacher Demo
 Make your prediction…what is in the
beakers? What can we do to figure out
what is in the beakers?
 What do you think will happen?
 Watch closely…keep watching!
 Write your observations
 What was your “hint” that a chemical
change occurred?
FRIENDLY REMINDERS!!
**Absolutely none of the lab chemicals should
come in contact with your mouth, eyes, or be
breathed deeply!!
**Appropriate behavior at all times, LISTEN!
**This is a group grade, so put everyone’s name at
the top of your paper right now.
 GROUP 1 = SINK 1
 GROUP 2 = SINK 2
 GROUP 3 = SINK 3 ETC…
 GROUP 7 & 8 = SHARE A SINK
Group Roles
Leader: Reads the directions for each lab, keeps
group on task and following directions
Materials/Clean Up: collects, returns, cleans and
disposes of materials
Data Discussion Leader: Ensures there is a
conversation about each data table to share
information.
Quality Management: Ensures every student has
detailed quality answers written in complete
sentences using scientific language. REMEMBER,
ONLY ONE WILL GET LAB GUIDE FROM YOUR
GROUP WILL GET COLLECTED AND THAT WILL BE
EVERYONE’S GRADE!!
You MUST complete the
materials and prediction
boxes BEFORE you do the
experiment!!!
Mini Lab 2:
 Use the graduated cylinder to measure about
30 mL of vinegar
 Send your materials person up to pick up a
ziploc bag with baking soda in it for each group
 Add the 30 mL of vinegar to the baking soda in
the bag and SEAL THE BAG IMMEDIATELY
 Observe and record any changes that occur.
 Throw the zip lock bag in the trash AFTER YOU
HAVE DUMPED THE CONTENTS INTO YOUR
SINK.
Mini Lab 3:
 Measure 30 ml of vinegar into your
graduated cylinder.
 Send your materials person to get a cup of
milk, and a stir stick.
 Pour the vinegar into the milk and stir it
like you mean it!
 Observe and record any changes that occur
at this time.
 Send your materials person to throw the cup
and the stir stick in the garbage.
Mini Lab 4:
 Send your materials person up to get a
MYSTERY test tube for each group member
 Use the eyedroppers to add an eyedropper full
of the cabbage juice (purple liquid) into each
test tube…DO THIS ONLY ONCE
 Observe and record any changes that occur
 WAIT FOR FURTHER INSTRUCTIONS!!!
 Rinse your test tubes and return them to the
test tube rack. Flush your eyedroppers with
water. Rinse your bin & dry it! Clean up any
spills at your group!
Mini Lab 5:
 Send your materials person to the sink to get
approximately 5 ml of water in your graduated
cylinder
 Put the water into your film canister & close the lid!
 Break one Alka-Seltzer tablet in half and hold it up
in the air!
 ONCE WE ARE OUTSIDE…
 Put the Alka-Seltzer tablet into the film canister
and snap the lid TIGHTLY
 QUICKLY put the canister on the ground CAP
SIDE DOWN AND STEP BACK!
Your lab bin should be clean and
should contain all of the supplies it did
when you started!
 Clean, dry plastic bin
 1 graduated cylinder
 1 bottle of vinegar
 1 small beaker of cabbage juice
 2 pipettes (eyedroppers)
 1 packet of Alka-Seltzer
 1 film canister
