1. On the half sheet of paper:
List as many Physical Properties of matter you can think of. I’ll get you started
Color

2. Matter

3. Physical Properties of Matter
any property of matter that can be observed or measured without changing the identity of the matter
Examples
Hardness
color
shape
taste
state/phase
density
D = m V

4. Chemical Properties of Matter
any property of matter that describes a substance based on its ability to change into a new substance
Examples
flammability
reactivity with vinegar
reactivity with oxygen
Rust

5. Chemical or Physical Property?
Paper is white
Boiling point of H2O is 100oC
Zinc reacts with hydrochloric acid and creates hydrogen gas
Nitrogen does not burn
Sulfur smells like rotten eggs

6. Comparing Physical and Chemical Properties
Substance/Matter
Physical Property
Chemical Property
Helium
Less dense than air
Nonflammable
Wood
Grainy texture
Flammable
Baking soda
White powder
Reacts with vinegar to produce bubbles
Powdered sugar
Does not react with vinegar
Rubbing alcohol
Clear liquid
Red food coloring
Red color
Reacts with bleach and loses color
Iron
Malleable
Reacts with oxygen

7. Physical Change a change in shape, size, color, or state
a change without a change in chemical composition
a change that is reversible
Examples
tearing paper
cutting your hair
change in state

8. combining sulfuric acid and sugar
Chemical Change
a change in which a substance becomes another substance having different properties
a change that is not reversible using ordinary physical means
Changes that usually cause heat, sound, light, odor, fizzing/foaming, color changes
You usually need more than one of the above characteristics to be considered a chemical change!
Examples
combining sulfuric acid and sugar
burning a piece of wood
soured milk

9. Chemical or Physical Change?
Bending a Paper Clip
Baking a cake
The sublimation of carbon dioxide
Crushing an aluminum can
Vinegar and baking soda combining to create salt and water
