Classroom RulesReview the classroom rules which are posted at

the front of the class.

4/16

TextbooksCP Chemistry has 1 textbook. I will be signing

those out to you next class. Sadly, you will need to be BRING YOUR BOOKS to every class. If you leave your book in the classroom, you are STILL responsible for it, solely. We will be

relying heavily upon the textbook all year.

SyllabusI have provided you with a short syllabus which

includes your first homework assignment (to get signed and returned by Monday).

Do not start off the year with a zero! Turn that syllabus sign-off sheet IN!

5/16

MrLaFazia.com Forums (Optional)• This year I have started using an online forum to help you

collaborate on and discuss the course. It is at mrlafazia.proboards.com– (Most of the content is hidden from you, for now…I have

multiple courses on the site, but have not made everything viewable to each user).

– Follow the instructions in the “First Timers” section and choose an appropriate username for yourself. (Note: Forum sign-up IS optional, but it may prove to be a useful resource to you).

– I will add you to the C.P. Chemistry usergroup as soon as I receive your “Private Message” so that you can see our section.

6/16

The Scientific Method• On the following slides I have included some

notes on the Scientific Method. • We will be using this method extensively in

our first few labs so that you get some first-hand experience using it.– Note: You may have heard some of the steps of

the S.M. called by other names (this is fine—they are synonymous)

7/16

The Scientific Method

The scientific method is the only scientific way accepted to back up a theory oridea. This is the method on which all research projects should be based. TheScientific Method is used by researchers to support or disprove a theory.

8/16

The Scientific Method

The Scientific Method involves 5 steps: ObservationQuestionHypothesisMethod/ExperimentResult (w/ Conclusion)

9/16

The Scientific Method

Observation - You observe something in the material world, using your senses or tools which are basically extensions of those senses.

AH—Look at this!

10/16

The Scientific Method

Question - You ask a question about what you observe. State the problem or question.

11/16

The Scientific Method

Hypothesis - You predict what you think the answer to your question (or solution toyour problem) might be

12/16

The Scientific Method

Experiment - You figure out a way to test whether hypothesis is correct. The outcome must be measureable (quantifiable) Record and analyze data.

13/16

The Scientific Method

Result - You do the experiment using the method you came up with and record the results. You repeat the experiment to confirm your results by retesting. .

14/16

The Scientific Method

State Conclusion - You state whether your prediction was confirmed or not and try to explain your results.

If your original hypothesis was incorrectthen you must REVISE your hypothesis(write a new one! But you don’t “erase” theold one, of course)

15/16

Looking Ahead:Next class we will start applying the Scientific Method.

You will each have the opportunity to identify an experience from your own pasts where you applied the Scientific Method (probably without knowing it). [These will be shared with your classmates!]

We will also complete a basic lab activity which provides an excellent opportunity to discuss the Scientific Method.
