1. Record the date, title and page # in your table of contents.
PROPERTIES OF MATTER
In the science section of your composition book, title the page, “Properties of Matter”
Record the date, title and page # in your table of contents.

2. What is it?
You and your partner are going to take turns describing your favorite Christmas gift to each other.
Pick a person to begin describing.
As your partner is describing their gift to you, you will be drawing and coloring what they are describing to you.
When you are finished, you must describe your favorite gift and let your partner draw it.

3. Physical Properties Physical Property-
a property of matter that can be observed or measured without changing the identity of the matter

4. For Example:
Color
Odor
Volume (size)
Mass

5. Physical Properties Continued..
Solubility (ability to dissolve)
Ductility (ability to be pulled into a wire)
Malleability (ability to be pounded into thin sheets)
State (Solid, Liquid, or Gas)
Thermal Conductivity (ability to transfer heat)
Density (mass per unit volume)

6. CHEMICAL PROPERTIES
Chemical property- a property of matter that describes a substance based on its ability to change into a new substance with different properties.

7. For Example: Flammability/nonflammability Reactivity with acid
Reactivity with water
Reactivity with oxygen

8. Christmas and Physical Properties
Look at the drawing of your partners favorite Christmas present.
Make a list of all physical properties that you can think of that may be used to describe this present.

9. Difference between a Physical property and a Chemical property:
You can observe physical properties without changing the object.
You can observe chemical properties only by trying to change the object. (It may or may not change.)

10. PHYSICAL CHANGES
Physical Changes affect one or more physical properties of a substance.
For example: if you break a piece of chalk in two, you would be changing its physical properties of size and shape.
No matter how many times you break it it is still chalk.

11. Examples of Physical Changes:
Freezing water
Sanding wood
Cutting hair
Crushing a can
Bending a paper clip
Mixing oil and vinegar

12. CHEMICAL CHANGES
Chemical Change – occurs when one or more substances change into entirely new substances.

13. Don’t confuse chemical properties with chemical changes!!!!
A chemical property describes a substance’s ability to go through a chemical change.
A chemical change is the actual process in which that substance changes into another chemical substance. (the reaction)
