Review: Separating
Mixtures and States of Matter
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:
Sifter/sieve
2. Big rocks + tiny rocks: Hand
3. Sand + iron: Magnet
4. Gravel (tiny rocks) + salt: Sifter/sieve
5. Sugar + water: 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
•Matter is anything that has mass and takes up space.
•Solids, liquids, and gases are the 3 main types of matter.
What is 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. Solid2. Liquid3. Gas
The pyramid is an example of a…
a. solid b. liquid c. gas
Review!
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 quiz…

Properties of Waves

KIPP: Inspire Academy
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
WavelengthWavelength is the distance between any two crests or any two troughs (the length of a wave).
.
.
Crest
Trough
Wavelength
Wavelength
• 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.
FrequencyFrequency 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?
a.
b.
1 second
6 1/2 wavelengths per second
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!
