1. What is matter?
Bellwork: Put a check next to each item on the sheet that you believe to be matter.

2. Notes

3. Physical property
Property that can be observed WITHOUT changing the substance into a NEW SUBSTANCE with a new identity

4. Chemical Property
Property that can only be observed by changing the substance into a new substance.

5. Notes Volume – the amount of space that matter takes up.
Of a liquid – measure in a beaker or g.c.
Of a regular solid – L x W x H
Of an irregular object – displacement in a g.c.

6. Notes Matter has mass Mass – the amount of matter in an object
Living things – cells
Nonliving things - atoms

7. Density Density – the amount of matter in a given space.
Which is more dense a golf ball or table tennis ball? Why?
How do their volumes compare? Their masses?

8. Density
Density = Mass
Volume

9. Density can help identify a substance

10. Physical Properties (Fill in Spider)
Ways to physically describe matter:
density
physical state (solid, liquid ,gas, plasma at certain temperatures and pressures)
color
odor
solubility (the ability of substance to dissolve )

11. Some more examples of physical properties are:
melting point
boiling point
hardness
malleability
conductivity

12. Chemical Property
A chemical property describes an object/substances’ ability to change into something new.
FLAMMABILITY – Ability to burn
REACTIVITY – Ability to react chemically with another substance and form a new substance, with a new identity.

13. Some examples of chemical properties are:
paper burns
iron rusts
gold does not rust
wood rots
nitrogen does not burn
silver does not react with water
sodium reacts with water

14. In each of these, the substance's chemical property is its tendency to:
react
tarnish
corrode
explode

15. Physical vs. Chemical Properties
Wood
Physical Property:
Grainy texture
Chemical Property:
Flammable

16. Physical vs. Chemical Properties
Baking Soda
Physical Property:
White powder
Chemical Property:
Reacts with vinegar to produce bubbles

17. Physical vs. Chemical Properties
Iron
Physical Property:
Malleable (able to be shaped)
Chemical Property:
Reacts with oxygen to form rust

19. Physical and Chemical Changes
Same or Different

20. Physical Change Changes only the physical property of the substance
An example of a physical change occurs when making a baseball bat. Wood is carefully crafted into a shape which will allow a batter to best apply force on the ball. Even though the wood has changed shape and therefore physical properties, the chemical nature of the wood has not been altered. The bat and the original piece of wood are still the same chemical substance.

22. Ice melting: an example of physical change
The material itself is the same before and after the change. The change CAN be “undone.”

Ice melting: an example of physical change

23. Chemical Change
Occurs when one or more substances are changed into entirely NEW substances
They have different properties from the original substance
Some signs (or evidence) of chemical change are:
a gas is produced,
the temperature changes,
a substance disappears,
a solid is formed
a color change occurs,
a new odor is produced.

24. Examples of Physical and Chemical Changes
Physical Changes
Chemical Changes
Aluminum foil is cut in half.
Milk goes sour.
Clay is molded into a new shape.
Jewelry tarnishes.
Butter melts on warm toast.
Toast is burnt
Water evaporates from the surface of the ocean.
Rust forms on a nail left outside.
A juice box in the freezer freezes.
Gasoline is ignited.
Rubbing alcohol evaporates on your hand.
Hydrogen peroxide bubbles in a cut.
 A stick is broke in two.
Food scraps are turned into compost in a compost pile.
 A window is shattered.
A match is lit.
 A car is wrecked
You take an antacid to settle your stomach.
 Hair is cut
Your body digests food.

26. Summing it Up Physical Change: Chemical Change:
The matter is the same.
The original matter can be recovered.
The particles of the substance are rearranged.
Chemical Change:
The matter is different.
The old matter is no longer present.
The original matter cannot be recovered.
