1. + Catalyst (Left Page): How would you describe the two images above? 10.01.2008 – General Science

2. + Objective SWBAT identify & distinguish between physical and chemical properties.

3. + Physical & Chemical Properties – 10.01.2008

4. + Physical Properties – any property that can be observed or perceived w/o changing identify

5. + Physical Properties Physical Properties – any property that can be observed or perceived w/o changing identify Observe phys. Props. Using senses No chemical rxns.

6. + Physical Properties - Properties that can be observed w/o chemical rxn - Can use senses Physical & Chemical Properties – 10.01.2008

7. + Physical Properties What are some examples of possible physical properties?

8. + Physical Properties What are some examples of possible physical properties? Color, mass, smell, melting point, boiling point, magnetism, phase, density, magnetism

9. + 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

10. + Chemical Properties Only observable in a chemical reaction Examples: flammability, how chemical reacts w/ H 2 O or other substances

11. + 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/ H 2 O, flammability, pH (acid or base) Physical & Chemical Properties – 10.01.2008

12. + Phys vs. Chem Take a minute and look @ your catalyst: When you made your description, did you include physical or chemical properties?

13. + 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?

14. + Science Fair Project Proposals & Rest of Period By Friday, October 10 th, 2008, your project proposals are due for Science Fair! (10 points) Work on your HW Packet
