mass (something that is matter!)
Composition of
Matter
WRITE THIS QUESTION ON THE TOP OF PAGE 44
WHAT’S THE DIFFERENCE BETWEEN SUBSTANCES
AND MIXTURES?
Matter

Anything that has mass and
volume

Examples:
A
brick has mass and takes up space
 A desk has mass and takes up space
 A pencil has mass and takes up
space
 Air has mass and takes up space
Substances

Substance: type of matter with a fixed
composition that cannot be separated
by physical means.
 Elements
– Substance made up of
atoms with the same identity
 Compound
– Atoms of two or more
elements combined
 Examples:
water (H2O) Carbon
Dioxide (CO2)
Mixtures

Mixture: Material made up of two or
more substances that can be
separated by physical means

Heterogeneous – mixture in which different
materials can be easily distinguished.

Examples: Pizza, fruit salad, granite

Homogeneous – mixture in which two or
more substances are uniformly spread out.

Examples: vinegar, salt water, coffee
Notice the
uniform
appearance
Salt Water
Concept Map

Cut out the terms from the first page in your
packet.

On the top of page 43, write:

Answer: Mixtures can be separated by
physical means whereas substances
cannot.

You will glue the terms on page 43 and
draw a picture of your choosing to
represent each type of substance and
mixture.

Warm Up: On page 45 of your lab book write down
this fun fact about matter!

Liquids, solids and gases are the most common 3 states
of matter on Earth, however, much of the matter of
universe is in the form of hot plasma
Types of Mixtures –
Page 46

Question: How can you determine which type of
mixture something is?

Solution: Homogeneous mixture of particles so small
that they cannot even be seen with a microscope
and will never settle to the bottom of their
container.

Examples: Vinegar, Soda (unopened), Hydrogen
Peroxide
Types of Mixtures

Colloid: type of mixture with particles that are larger
than those in solution but still too light to settle out.

Example: Milk (Water and Fat), Fog (water and air),
Cool Whip

*Detecting colloids is sometimes difficult so shining a
beam of light at a colloid will make the light scatter –
this scattering of light by a colloid is called The Tyndall
Effect.

Effect
Fog
Types of Mixtures

Suspension: heterogeneous mixture containing a
liquid in which visible particles settle.

Example: Italian dressing, muddy pond water,
chocolate milk

*Hint – If it needs shaking to mix, then it’s a suspension
Italian Dressing
Muddy water
Chocolate milk
Poppy’s Grocery Mart - 47
• On page 47 in your
lab book, glue in the
Poppy’s Grocery Mart
Page.
• Cut out the different
types of matter and
glue them into the
correct column –
Solutions, Colloids or
Suspensions.
• There are 4 products
in each column.
What kind of
mixture?
IN YOUR LAB BOOK ON PAGE 48,
DRAW THE PICTURE AND TELL ME WHAT

Up: In your lab book

Combining Atoms

There are over one hundred different types of
atoms and they often times combine to make new
substances known as molecules and compounds
Molecule
Compound
Results from the
bonding of
two or more atoms
A substance that
contains two or more
different elements
(atoms)
Example – Oxygen Gas (O2)
Example – Water (H2 O)
Compounds are molecules but not all molecules are compounds

Creating Mixtures – Part 1


Pour cup A into cup B and mix the
contents with a glass stirring rod.
Observations/Questions



Describe what you see in the cup.
Draw a picture of what you see in the
beaker.
Using any means necessary, try to
separate the mixture back into its
original parts. Was it possible to
separate the mixture? Why or why not?
Creating Mixtures – Part 2


Pour cup C into cup D and mix the
contents with a glass stirring rod.
Observations/Questions
