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. Solid

2. Liquid

3. 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.

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.

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?

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!
