1. Chemistry: Matter

2. Science: Lesson 1 What are Properties of Matter?
What is matter?
What are some examples of matter?

3. Elements Elements are building blocks of matter
Can’t be broken down into smaller pieces
Only a few combine to make up all kinds of matter

4. More About Elements
Only a few elements exist in nature in pure form. Which precious metal is pure?
What is your body mostly made of?
Carbon, hydrogen, oxygen and nitrogen
make up 96% of you!

5. Physical Properties of Matter
What are physical properties?
How we describe it just from our observations
We can describe something’s:
Color
Hardness
State of matter
Magnetism
Dissolves in other substances
Temperature at boiling point
Temperature it freezes
Conducts electricity
Mass
Weight

6. Mass vs. Weight Mass = how much matter makes up an object
Weight = how much gravity pulls an object
Imagine you go to
the moon.
Which changes…
your mass
or your weight?
You weigh six times more on the Earth!

7. Chemical Properties of Matter
Tells how the substance may form a new substance when mixed with something else
Examples:
Wood is flammable – ash and gases
Water is not flammable
Iron can rust– combines with oxygen
Gold does not rust
