Catalyst (Left Page): How would you describe the two images above?
10.01.2008 – General Science
+Objective
SWBAT identify & distinguish between physical and chemical properties.
+
Physical & Chemical Properties – 10.01.2008
+Physical & Chemical Properties – 10.01.2008
Physical Properties – any property that can be observed or perceived w/o changing identify
+Physical Properties
Physical Properties – any property that can be observed or perceived w/o changing identify
Observe phys. Props. Using senses
No chemical rxns.
+
Physical Properties
- Properties that can be observed w/o chemical rxn- Can use senses
Physical & Chemical Properties – 10.01.2008
+Physical Properties
What are some examples of possible physical properties?
+Physical Properties
What are some examples of possible physical properties?
Color, mass, smell, melting point, boiling point, magnetism, phase, density, magnetism
+
Physical Properties
Phys. Prop. Definitions & Examples
- Properties that can be observed w/o chemical rxn- Can use senses- Ex: Color, mass, smell, melting pt, boiling pt, magnetism, phase, density, magnetism
Physical & Chemical Properties – 10.01.2008
+Chemical Properties
Only observable in a chemical reaction
Examples: flammability, how chemical reacts w/ H2O or other substances

Physical Properties
Phys. Prop. Definitions & Examples
Chem. Properties
- Properties that can be observed w/o chemical rxn- Can use senses- Ex: Color, mass, smell, melting pt, boiling pt, magnetism, phase, density, magnetism
- Only seen during rxns.- Ex: how reacts w/ H2O, flammability, pH (acid or base)
Physical & Chemical Properties – 10.01.2008
+Phys vs. Chem
Take a minute and look @ your catalyst:
When you made your description, did you include physical or chemical properties?
+Summary
Create a summary of today’s notes that answer the following questions:
(1) What is the difference between physical & chemical properties?
(2) What is an example of each of them?
