Descriptive
Chemistry
Knowledge of specific facts of chemistry is essential for an understanding
of principles and concepts. These descriptive facts, including the chemistry
involved in environmental and societal issues, should not be isolated from
the principles being studied but should be taught throughout the course
to illustrate and illuminate the principles. The following areas should
be covered:
-
Chemical reactivity and products of chemical reactions
-
Relationships in the periodic table: horizontal, vertical, and diagonal
with examples from alkali metals, alkaline earth metals, halogens, and
the first series of transition elements
-
Introduction to organic chemistry: hydrocarbons and functional groups (structure,
nomenclature, chemical properties). Physical and chemical properties of
simple organic compounds should also be included as exemplary material
for the study of other areas such as bonding, equilibria involving weak
acids, kinetics, colligative properties, and stoichiometric determinations
of empirical and molecular formulas.

Laboratory
Work
The differences between college chemistry and the usual secondary school
chemistry course are especially evident in the laboratory work. The AP
Chemistry Examination includes some questions based on experiences and
skills students acquire in the laboratory: making observations of chemical
reactions and substances; recording data; calculating and interpreting
results based on the quantitative data obtained; and communicating effectively
the results of experimental work. Colleges have reported that some AP candidates,
while doing well on the examination, have been at a serious disadvantage
because of inadequate laboratory experience. Meaningful laboratory work
is important in fulfilling the requirements of a college-level course of
a laboratory science and in preparing a student for sophomore-level chemistry
courses in college.
Because chemistry professors at some institutions ask to see a record
of the laboratory work done by an AP student before making a decision about
granting credit, placement, or both, in the chemistry program, students
should keep reports of their laboratory work that can be readily reviewed.
