Figure references in the body of the text and
those found with the illustrations always appear

Chapter Components
A list of learning objectives is presented at the
beginning of each chapter. These objectives are
the topics covered and goals to be achieved in the
chapter. These objectives are listed in the order
that the topics are presented in the chapter. Re-
view the objectives before reading the chapter to
get an understanding of the material to come. Af-
ter completing the chapter, review the objectives
once more as a review of chapter material.
A list of technical terms immediately follows
the chapter objectives. These terms are presented
in alphabetical order. After completing a chapter,
review and defi ne each term. If a term(s) cannot
be defi ned at that time, go back and review the re-
lated section in the chapter.
A chapter summary is included at the end of
each chapter. The summary provides a brief over-
view of the material covered in the chapter. Review
the summary after reading a chapter. If something
in a summary is not understood, go back and re-
view the related section in the chapter.
Chapter review questions are presented at the
end of each chapter. After completing a chapter,
answer all of the questions on a separate sheet of
paper. This is a great way to review the material
just presented in the chapter.
Suggested activities are presented after the re-
view questions. These activities are related experi-
ences that enhance the understanding of the mate-
rial just covered in the chapter.
