Separating Mixtures- Main Idea!
Pure substances are made of 1 kind of
material; cannot be separated into
other parts
Mixtures are made of 2 or more
materials; CAN be separated back into
individual components
Tools Used To Separate
sifter/sieve
filter
magnet
hot
plate
What Tool Should We Use?
1. Gravel (tiny rocks) + sand:
2. Big rocks + tiny rocks:
3. Sand + iron:
Hand
Magnet
4. Gravel (tiny rocks) + salt:
5. Sugar + water:
Sifter/sieve
Hot plate

States of Matter- Main Idea!
We can decide what state of matter an
object is in by looking at its volume
and shape.
Volume = the amount of space
something takes up
What is matter?
•Matter is anything that has mass and
takes up space.
•Solids, liquids, and gases are the 3 main
types of matter.
Solids
• A solid has
definite (fixed)
shape and a
definite volume.
• Solid molecules
are packed
closely together.
Examples of Solids
How can you describe a solid item?
Liquids
• A liquid has a definite (fixed) volume but
no shape of its own.
• Liquids take the shape of their
containers
• Liquid molecules move loosely.
Liquids can flow or be poured easily.
Liquids change their shape depending
on the container they are in.
Examples of Liquids
Gases
• Gases don’t have definite volume or
shape.
• Gas molecules can move around freely.
• Gases spread out and change their shape
to fill up whatever container they are in.
Examples of Gases
Do You Get It?
Which of these would be an
example of a liquid?
The type of matter that
is inside
this balloon is a…
1. Solid
2. Liquid
3. Gas
The pyramid is an example of a…
a. solid
b. liquid
c. gas
What am I?
I’m an object with definite volume and shape.
I’m an object with no definite shape but definite volume.
I’m a object with neither definite volume nor shape.
Now, some new stuff before

The 5 Properties of Waves…?
Why do we care about WAVES
in our Matter and Energy unit?
Light and sound energy
travel in waves.
5 Properties of Waves
• Crest
• Trough
• Wavelength
• Frequency
• Energy
Crest
.
.
Trough
Wavelength
Wavelength is the distance between
any two crests or any two troughs
(the length of a wave).
Wavelength
Crest
.
.
Wavelength
Trough
• A shorter
wavelength has
less distance in
between the two
points.
• A longer
wavelength has
more distance in
between the two
points.
Class Check: Which one has a
longer wavelength?
a.
b.
Frequency
Frequency is the speed
of a wave.
• measured by the
number of wavelengths
that pass through a point
in one second.
• A higher frequency
means the wave
occurs (happens)
faster
• A lower frequency
means the wave
occurs slower
Class Check: Which one has a
higher frequency?
1 second
a.
6 1/2 wavelengths per second
b.
About 3 wavelengths per second
Wavelength & Frequency Together
• The higher
the frequency,
the shorter the
wavelength ;
• The lower the
frequency, the
longer the
wavelength.
Energy
• High frequency waves have
high energy
• Low frequency waves have low
energy.
Class Check: Which one is the
higher energy wave?
a.
b.
High frequency
waves have
high energy!
Low frequency
waves have low
energy!
