1. Characteristic Properties of Matter All objects maintain a certain color, odor, density, and reactivity. NCES.6.P.2 - Understand the structure, classifications and physical properties of matter NCES.6.P.2.3 – Compare the physical properties of pure substances that are independent of the amount of matter present including density, melting point, boiling point and solubility to properties that are dependent on the amount of matter present ot include volume, mass and weight.

4. Lesson Questions:
How can different types of matter be distinguished from each other?
What are physical properties of matter?
What are the chemical properties of matter?
Vocabulary:
Physical properties, volume, mass, density, weight, solubility, solute, solvent

5. Getting to Know: Characteristic Properties of Matter
How many different kinds of matter are around you right now?
There might be too many to count. Matter can be soft and flexible, like the fabric in the clothes you are wearing. Or it can be hard and tough, like wood or metal. It can be a wet liquid, like water, or an invisible gas, like the gases in the air around you.

6. REMEMBER:
Matter is anything that has mass and takes up space!
Each type of matter can be identified by its properties.

7.  A sample of a substance can have any
mass 
volume
temperature

8. Mass:
the amount of matter in an object
measured with a balance

9. Volume: the amount of space an object takes up
measured with a ruler or graduated cylinder

10. a measure of how hot or cold a substance is.
 Temperature:
a measure of how hot or cold a substance is.
(the kinetic energy of, energy of notion of the particles in a substance)
Measured with a thermometer.

11. Density
Density - density is a measure of how many particles are packed together into a certain amount of space Density is an object's mass divided by its volume;

12. Demonstration!!!!
What happens when you pour honey, water and oil into the same container?

13. The honey always sinks to the bottom.
Then, there is a layer of water in the middle.
The oil layer is always on top.
Even if you shake the container, each layer will settle again because of their densities.

14. The mass of oil per unit volume is the least. The oil rises to the top.
The density of honey is the greatest and it sinks to the bottom.

15. What Are Physical Properties of Matter?
  The physical properties of a substance are properties that can be observed with the senses and can be determined without destroying or changing the substance.
The substance stays the exactly the same!

16. Physical Properties
Are characteristics or features that describe matter.

17. Examples of physical properties
Color
Size (mass, volume)
Shape
Texture
Smell
Temperature
State – (solid, liquid, gas)

18. Examples of a physical change
Mixture -Mixtures are absolutely everywhere you look. Most things in nature are mixtures. Look at rocks, the ocean, or even the atmosphere. They are all mixtures.
Mixtures are about physical properties, not chemical ones. That statement means the individual molecules enjoy being near each other, but their basic chemical structure DOES NOT change when they enter the mixture. 
Solution -sugar water is just sugar and water!
Each of the substances in that glass keeps its own chemical properties. 

19. DEMONSTRATION
MIXTURE –
SOLUTION -

20. More Physical Changes Melting Boiling Evaporation/Vaporization
Freezing
Condensation
ALL CHANGES IN STATE (phase) ARE PHYSICAL CHANGES
PHYSICAL CHANGES CAN BE UNDONE

21. Characteristic Properties
Properties that are used to help identify substances
Are Properties that DO NOT change
ARE properties of a substance
ARE NOT properties of an object
Are properties that do NOT change as mass, volume and/or shape of a substance are changed.

22. Characteristic properties examples include
hardness pH
flammability
density
boiling point
melting point
solubility
conductivity

23. Because characteristic properties are usually not affected by physical changes, they can be used to identify matter

24. What Are the Chemical Properties of Matter?
The chemical properties of a substance describe how the substance changes into other substances.
The original substance is changed when you observe a chemical property!

25. Burning Rusting Cooking Film Processing
Examples of Chemical Properties/Changes:
Burning
Rusting
Cooking
Film Processing
Any change that causes NEW matter to be formed
CHEMICAL CHANGES CANNOT BE UNDONE

26. Misconception:  Boiling point and freezing point are chemical properties of matter.
boiling point and freezing point are physical properties.
When matter changes state, such as from solid to liquid or from liquid to gas, it is not a chemical change. The matter’s chemical identity remains the same.
The water molecules in liquid water are the same as those in ice and water vapor.  

27. Video - Physical and Chemical Properties of Matter
Physical properties of matter include its hardness and color;
Chemical properties are identified by observing what happens when one substance reacts with another substance.

28. Solubility Solutes and Solvents
Solvent - The substance present in the greater quantity in a solution is the solvent,
Solute – the substance present in a lesser quantity in a solution is the solute.
A solute dissolves in a solvent.

29. A substance is soluble if it is able to dissolve in another substance
A substance is insoluble if it cannot dissolve into a specific solvent.
Stirring, solute particle size, and temperature of the solvent all affect the rate of dissolving.
Solubility - is the measure of how much solute can be completely dissolved in a solvent
Video: Solubility

33. Review - Characteristic Properties are...
Properties that do not change when mass or volume change.
density
boiling point
melting point
freezing point
Properties that are used to help identify substances

34. #1 - How can different types of matter be distinguished from each other?
Answer: Different types of matter can be identified by observing and measuring the physical and chemical characteristic properties of matter.
The characteristic properties of a substance will be the same no matter where the substance is or how much of it there is.  

35. #2 - What are physical properties of matter?
Answer: The characteristic physical properties of matter are
color, hard, soft
odor, taste
density, 
solubility, 
melting point,
boiling point,
electrical conductivity.
These are properties that can be observed without chemically changing the substance.

36. #3 - What are chemical properties of matter?
Answer: The characteristic chemical properties of matter are
acidity
basicity
combustibility (ability to burn)
Reactivity (how it reacts chemically with another substance)

37. Properties of Matter include:
How it looks (shiny, dull, colored)
How it feels (hard, soft, rough, smooth)
How it smells (sweet, salty, flowery)
How it sounds (loud, soft, hollow)
How it tastes (sweet salty, bitter, sour)
What it does (bounce, bubble, tear)

38. Chemical Changes Any change that causes NEW matter to be formed
Energy is needed!!!!!!!
