2. Is anything that has mass and takes up space.
Matter

3. A pure substance is a single kind of matter that is pure, meaning it
always has a specific makeup. For example: table salt, sugar and
baking soda
Pure Substance

4. Physical
properties
&
Chemical
properties
Every form of
matter has 2
kinds of
properties.

5. A physical
property is a
characteristic of
a pure
substance that
can be observed
without changing
it into another
substance.

6. For example, a
physical property of
water is that it freezes
at a temperature of 0
degrees Celsius.

7. Physical properties can be used
to classify matter.
Examples of physical
properties:
•Melting Point
•Texture
•Color
•Flexibility
•Density

8. A chemical property is a
characteristic of a pure substance that
describes its ability to change into
different substances.

9. Examples:
The ability of a substance to catch fire
The ability to react: rusting
The ability to form a new substance or property
(baking a cake, burning toast).
Chemical properties are also
used to classify substances.

10. An element is a pure substance that
can’t be broken down into any other
substance by chemical or physical
means.
Elements are the simplest substances.

11. You are already familiar with some elements.
*Aluminum which is used to
make outdoor furniture and foil.
*Pennies are made from zinc
(but covered in copper)

12. A mixture is made up of 2 or more
substances – elements or compounds, or
both – that are held together in the same
place but NOT chemically combined.
Can you think of any other examples?

13. Homogenous Mixtures:
This is a mixture that is so evenly
mixed that you cannot see the different
parts.
Heterogeneous Mixtures:
This is a mixture where you can see
the different parts.

14. An example of a
homogenous mixture!
Can you think of any
examples?
A solution
is……

Sugar water
Air ( nitrogen gas and oxygen gas as well as other gases)
