Bellringer:

What is the name of the temperature for when a solid changes into a liquid?

Bellringer:

Why would air be considered a mixture? Think about what air is

composed of.

Classify matter

according to its

composition and physical properties.

Today’s objectives:

Review types of matter.

Describe and illustrate the

particle arrangement

of matter.

The color of the sunset depends on how many particles are mixed in the air to scatter the light.

Recall, that we learned one physical property used to describe matter is color.

What do you think these particles in the air come from?

Pollution, dust, water vapor, etc.

As the Sun gets lower in the sky, its light passes through more of the atmosphere to reach you. Even more of the blue and

violet light is scattered, allowing the reds and yellows to pass straight through to your eyes without all that competition

from the blue and violet colors.Large particles of dust, pollution, and water vapor in the

atmosphere reflect and scatter more of the reds and yellows, sometimes making the whole western sky glow red.

The fact that the air particles scatter light is another physical property of

certain groups of matter.

Today’s objectives:

We are going to Review the types

of matter.

Previously we discussed the classification of matter based on its composition.

Type of matter: Type of matter:

Properties of this type of matter:

1.Combined

2.Can not be broken down

3.Considered to be “pure” matter

Properties of this type of matter:

1.Combined

2.Can be broken down

3.Considered to be “impure” matter

What were these two main types of matter?

The 2 subgroups of substances are ________________ and ________________. Elements Compounds

Can you tell us the two types of substances?

The 2 subgroups of substances are ________________ and ________________. Homogeneous Heterogeneous

Can you tell us the two types of

mixtures?

Organize our thoughts into the following graphic organizer:

Particles are even mixed throughout. Contains particles that are not visible.

Particles are NOT evenly mixed throughout. Contains particles that are visible.

This is called the Tyndall effect.

Now we will Classify matter

according to its

composition and physical properties.

Today’s objectives:

the types of matter.

We are going to be viewing samples of matter. Then we will classify these samples based on what you know.

When we determine the appropriate place for the sample, write the name of the

sample in the appropriate block on the line provided.

Quickly and quietly move your desks apart.

Classify matter

according to its

composition and physical properties.

Today’s objectives:

Review types of matter.

Describe and illustrate the

particle arrangement

of matter.

We will draw and describe the particles in certain samples of matter.

Beads Fruit juiceFog

These samples are what phases of matter?

Beads Fruit juiceFog

Draw and briefly describe the particle arrangement of each phase

of matter.

Beads

For instance particle arrangement of the beads would look like this….

Particles are closely packed together.

Fruit juice

Fog

Now you draw and briefly describe the particle arrangement of the fog

and the juice.
