Syllabus

PrerequisitesPrerequisites • one year of high school chemistry (or a

grade of “C” or better in GNC 088 or CHM 103)

• four semesters of high school academic math (including algebra).

• SEE YOUR INSTRUCTOR IMMEDIATELY IF YOU DO NOT HAVE THESE PREREQUISITES!

Syllabus

COURSE PHILOSOPHY

• Grades are based on performance, not effort.

• You are expected to be able to recall and use information from a basic high school level chemistry course (the equivalent of our GNC 088 or CHM 103).

COURSE PHILOSOPHY

• Before you drop the course, see me

What are you expected to learn?

• Use the list of learning objectives at the beginning of each chapter as a guide

• The class will consist of

• class discussions, text readings, homework problems, quizzes/exams, and a lab (take labs seriously)

The Scientific Method

An orderly and systematic approach to gathering information in order to answer questions about the world

Scientific Method1. Observation – To observe any phenomenon in

nature

Qualitative Quantitative

red 700 nm wavelength

far from the earth 300 million light years

microscopic smaller than 1 um

burns quickly burns at 1 cm candle per minute

hot 350 degrees C

Qualitative: involves quality or kind Quantitative: involves the measurement of quantity, amount, a number

Quantitative

observation (quantities with understood units)

1. humans have 10 fingers

2. the speed limit is 55 miles per hour

3. class is 1 hour long

4. acceleration due to gravity is 9.8 m/s2

Qualitative Qualitative observationsobservations

(not as precise, descriptive (not as precise, descriptive adjectives)adjectives)

1.1.humans have humans have many many

fingersfingers

2.2.the speed limit is the speed limit is fastfast

3.3.class is class is longlong

4.4.acceleration due to acceleration due to

gravity is gravity is largelarge

2. Question – To formulate questions about the phenomenon observed

3. Hypothesis – To propose an educated guess as to the answer for the question

4. Experiment – To test the hypothesis

Scientific Method continued…

The control/experiment group

Control:

• the group that is not being change; kept constant-“business as usual”;

• the group that gets no chocolate

• control group is not being exposed to the "treatment

Experimental group:

• the group that actually receives treatment (chocolate)

Scientific Method continued…

5. Data/results – To gather and interpret information obtained from the experiment

6. Conclusion -To make a decision as to whether your results support or do not support your hypothesis.

7. Theory - A well-tested explanation for experimental data based on a set of hypothesis

theory is not always included at one of the steps in the scientific method

Scientific Law• a statement of fact meant to explain, in concise terms,

an action or set of actions; accepted to be true and univseral

• Often expressed as a single mathematical equation the law of gravity, the law of thermodynamics

Hypothesis• educated guess based upon observation; rational

explanation of a single event/phenomenon based on observations; has not been proved.

Theory• A set of tested hypothesis that gives an overall

explanation of some natural phenomenon.• Subject to change as more information becomes

available– evolution
