Lab Activity
IV. Descriptive Chemistry (10–15%)
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:
1. Chemical reactivity and products of chemical reactions
2. 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
3. Introduction to organic chemistry: hydrocarbons and
functional groups (structure,nomenclature, chemical
properties)
Review (nomenclature, safety, etc.)

The AP College Board suggests a
total of 22 labs. NMSI has
provided a protocol for all 22 labs
at their website.
The numbers beside the labs
indicate the AP number.
