1. 11-15-16 Pick up new note packet and video sheet
Put a divider behind the last unit
This unit is called classification of matter.

2. Classification of matter
Ms. Pici
Iroquois Middle

3. Whiteboard with your partner
What types of matter are there? How do we classify matter?

4. Matter
DEFINE MATTER: Anything that has mass (molecules) and volume (takes up space).

5. Bill nye video
Phases of matter

6. Phases of matter SOLID LIQUID GAS
- Desk EXAMPLE Water EXAMPLE Air, CO₂
- Definite Shape SHAPE - Takes shape of SHAPE Takes shape of
the container the container
- Not definite Not definite
- Cannot be changed ABILITY T Cannot be squeezed or ABILITY TO - Can be squeezed
or compressed CHANGE or compressed CHANGE or compressed
- Definite volume VOLUME Definite volume VOLUME No definite volume
PARTICLE PARTICLE
ARRANGEMENT ARRANGEMENT
- Closely (tight) packed Looser, flow free
but vibrating

7. Which difference is the most important? Why?
A three way tie
Similarity: Definite Volume
Difference: Shape
Molecule arrangement
Similarity: Mass & volume
= matter
Difference: Shape & space
packed vs. free
Molecule arrangement
Similarity: No Definite
Shape
Difference: Gas is free to move
Compressed
Molecule arrangement
Which difference is the most important? Why?
The molecules are arranged and moving (energy). It determines the phase.

8. Define Plasma: 4th phase; hot and electrically charged
Define Plasma: 4th phase; hot and electrically charged (Example: lightning, sun)

9. Kinetic molecular theory

10. Kinetic molecular theory
What does each word mean?
Theory – idea
Molecular – molecules (matter)
Kinetic – movement
Define the Kinetic Molecular Theory: Idea that molecules are ALWAYS moving.

11. TEMPERATURE & KINETIC ENERGY
- a lot of energy medium little energy
HOT WARM COLD

12. FILL IN THESE STATEMENTS:
AN INCREASE IN TEMPERATURE CAUSES MOLECULES TO MOVE
faster and spread out.
A DECREASE IN TEMPERATURE CAUSES MOLECULES TO MOVE
Slower and get closer together.

13. Video: Physical Properties

14. Properties
DEFINE PHYSICAL PROPERTY: An observable quality or feature.

15. Absorption or reflection of light
Color
Absorption or reflection of light

16. Density
M/V ; mass per volume ratio

17. Melting/freezing point
Solid to liquid or liquid to solid

18. Boiling /condensation point
Liquid to gas or gas to liquid

19. Ductility
Can be pulled into a wire

20. malleability
Can be molded or shaped

21. Physical state
Solid, liquid, gas, plasma

22. luster
shininess

23. solubility
Can be dissolved

24. Brittleness
Shatters when struck

25. hardness
Resistance to being scratched

26. elasticity
Stretches and returns to it’s shape

27. Odor
How it smells

28. Electrical/ thermal conductivity
Can carry a current; heat

29. Chemical Properties
How a material reacts with something else.

30. Ability to burn (combustible/flammability) Wood; Paper
PROPERTY PICTURE EXAMPLE
Ability to burn (combustible/flammability)
Wood; Paper
Ability to rust
Metal; Iron; Copper
Ability to react with acid
Vinegar; Baking Soda;
Digestive Acid

31. Categorize the physical vs. chemical change
Take the following list and separate them into two categories. Label each category.
1. Burning wood Ripping paper in half
3. Digesting Food Rusting car
5. Popping a balloon Ice cube melting
7. Lighting a match Coloring a picture

32. Physical vs chemical changes
Category A: Chemical Changes Category B: Physical Changes
Burning Wood Popping a balloon
Rusting Car Ripping paper in half
Lighting a match Ice cube melting
Digesting Food Coloring a picture

33. What is the most important difference between those items in Category A and Category B?

34. Chemical changes make NEW substances with new properties.
Can’t get it back.

35. DEFINE PHYSICAL CHANGE: phase changes; a change that doesn’t permanently alter the substance.
DEFINE CHEMICAL CHANGE: Cannot undo; makes a new substance.
Chemical Changes ALWAYS involve the release or absorption of energy, but not all Physical Changes do.

36. Endothermic vs exothermic

37. ENDOTHERMIC EXOTHERMIC
- molecules move faster (spread out) VERSUS - molecules move slower (get closer)
- Heat entering heat exiting
- temperature increases temperature decreases
- heating cooling

38. Phase Changes
