1. Bellringer:
What is the name of the temperature for when a solid changes into a liquid?

2. Bellringer: Why would air be considered a mixture
Bellringer: Why would air be considered a mixture? Think about what air is composed of.

3. Today’s objectives:
Review types of matter.
Classify matter according to its composition and physical properties.
Describe and illustrate the particle arrangement of matter.

4. Recall, that we learned one physical property used to describe matter is color.
The color of the sunset depends on how many particles are mixed in the air to scatter the light.

5. What do you think these particles in the air come from?
Pollution, dust, water vapor, etc.

6. 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.

7. The fact that the air particles scatter light is another physical property of certain groups of matter.

8. We are going to Review the types of matter.
Today’s objectives:
We are going to Review the types of matter.

9. What were these two main types of matter?
Previously we discussed the classification of matter based on its composition.
What were these two main types of matter?
Type of matter:
Properties of this type of matter:
Combined
Can not be broken down
Considered to be “pure” matter
Can be broken down
Considered to be “impure” matter

10. Can you tell us the two types of substances?
The 2 subgroups of substances are ________________ and ________________.
Elements

11. Can you tell us the two types of mixtures?
The 2 subgroups of substances are ________________ and ________________.
Homogeneous
Heterogeneous

Would be found on the periodic table.
Two or more elements chemically combined. Has a chemical formula.
Particles are even mixed throughout. Contains particles that are not visible.
Particles are NOT evenly mixed throughout. Contains particles that are visible.
Another name for this group:

Does not settle if left standing still.
This is called the Tyndall effect.
Light Test shows:
Settles if left standing still.
light goes through
Light Test shows:
light scatters

14. Today’s objectives: the types of matter.
Now we will Classify matter according to its composition and physical properties.
the types of matter.

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

16. When we determine the appropriate place for the sample, write the name of the sample in the appropriate block on the line provided. DO NOT GLUE PICTURES UNTIL THE END!

25. Today’s objectives:
Review types of matter.
Classify matter according to its composition and physical properties.
Describe and illustrate the particle arrangement of matter.

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

27. These samples are what phases of matter?
Fruit juice
Beads
Fog

28. Draw and briefly describe the particle arrangement of each phase of matter.
Fruit juice
Beads
Fog

29. For instance particle arrangement of the beads would look like this….
Particles are closely packed together.
