2. Question of the Day What are some of the ingredients or components in
Section 1 What Is Matter?
Question of the Day
What are some of the ingredients or components in
the following items: loaf of bread, textbook, bicycle.
Can you break down any of the ingredients or
components even further? For example, one of the
components of a book is obviously paper, but what
are the components of paper?
Record your thoughts for your QOD.

3. Objectives Describe the two properties of all matter.
Section 1 What Is Matter?
Objectives
Describe the two properties of all matter.
Identify the units used to measure volume and mass.
Compare mass and weight.
Explain the relationship between mass and inertia.

4. Section 1 What Is Matter?
Matter
What Is Matter? Matter is anything that has mass and takes up space.
Matter in the Universe Everything in the universe is made up of some type of matter.

5. Section 1 What Is Matter?
Matter and Volume
Liquid Volume Liters (L) and milliliters (mL) are the units used most often to express the volume of liquids.

6. Volume of a solid = length  width  height
Section 1 What Is Matter?
Matter and Volume, continued
Volume of a Regularly Shaped Solid Object To find the volume of a regularly shaped solid object use the following equation:
Volume of a solid = length  width  height
Volume of an Irregularly Shaped Solid Object You can find the volume of an irregularly shaped object by measuring the volume of water that the object displaces.

8. Section 1 What Is Matter?
Matter and Mass
The Difference Between Mass and Weight Weight is the measure of the gravitational force exerted on an object. The more mass an object has, the greater the gravitational force on the object and the greater the object’s weight.
Measuring Mass and Weight The SI unit of mass is the kilogram (kg).
Weight is a measure of gravitational force and is expressed in the SI unit of force, the newton (N).

Inertia
What Is Inertia? Inertia is the tendency of an object to resist a change in motion.
Mass: The Measure of Inertia An object that has a large mass is harder to move and harder to stop than an object that has less mass. The reason is that the object with the large mass has greater inertia.

11. Question of the Day If you were asked to describe an orange to someone
Section 2 Physical Properties
Question of the Day
If you were asked to describe an orange to someone
who had never seen an orange, what would you tell
the person? How would you describe a grapefruit
and a lemon? How do you distinguish between
similar objects?
Write down your thoughts for your QOD.

12. Objectives Identify six examples of physical properties of matter.
Section 2 Physical Properties
Objectives
Identify six examples of physical properties of matter.
Describe how density is used to identify substances.
List six examples of physical changes.
Explain what happens to matter during a physical change.

13. Section 2 Physical Properties
What Are Physical Properties? A physical property of matter can be observed or measured without changing the matter’s identity.

Identifying Matter You use physical properties to identify matter.
Density Density is the amount of matter in a given space, or volume. The two balls below have different densities.

Liquid Layers The graduated cylinder below contains six liquids. Each liquid is a different density so the liquids form layers.
Density of Solids Knowing the density of a substance can also tell you what kind of substance it is.

Solving for Density To find an objects density (D), first measure its mass (m) and volume (V). Then use the following equation:
D = m/V

Matter and Physical Changes Physical changes DO NOT change the identity of the matter.

22. Section 3 Chemical Properties
Question of the Day
Look at the picture of this car. Describe where you have seen other examples of rusting. What do all your examples have in common?

23. Objectives Describe two examples of chemical properties.
Section 3 Chemical Properties
Objectives
Describe two examples of chemical properties.
Explain what happens during a chemical change.
Distinguish between physical and chemical changes.

24. Section 3 Chemical Properties
Comparing Physical and Chemical Properties You can observe physical properties without changing the identity of the matter. Chemicals properties are more difficult to observe.
Characteristic Properties The properties that are most useful in identifying a substance are characteristic properties.

25. Chemical Changes and New Substances
Section 3 Chemical Properties
Chemical Changes and New Substances
What Happens During a Chemical Change? During a chemical change a substance changes chemical properties.
Signs of Chemical Changes Some common signs of chemical changes includes a change in color, odor, production of heat, fizzing, and so on.
Matter and Chemical Changes Chemical changes change the identity of the matter involved.

27. Physical Versus Chemical Changes
Section 3 Chemical Properties
Physical Versus Chemical Changes
A Change in Chemical Composition Physical changes do not change the chemical make-up of a substance while chemical changes do.
Reversing Changes Many physical changes are easily reversed, but most chemical changes cannot easily be reversed.
