Syllabus
Prerequisites
• 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!
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

The Scientific Method
An orderly and systematic approach
to gathering information in order to
answer questions about the world
Scientific Method
1. Observation – To observe any phenomenon in
nature
Qualitative: involves quality or kind
Quantitative: involves the measurement of quantity,
amount, a number
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
Quantitative
observation
(quantities with understood units)
Qualitative
observations
(not as precise, descriptive
adjectives)
1. humans have 10
1.humans have many
fingers
fingers
2. the speed limit is 55
2.the speed limit is fast
miles per hour
3. class is 1 hour long 3.class is long
4. acceleration due to 4.acceleration due to
gravity is 9.8 m/s2
gravity is large
Scientific Method continued…
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
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
