Preparation
Activity 2
Students will be working in teams for this activity. Divide the class into
teams of four students. Each team will evaluate two case histories. If necessary,
have more than one team evaluate the same case histories.
Cut Masters 4.3, 4.4, 4.5, 4.6, and 4.7 along the dotted lines separating the
Primary Information, the Secondary Information, and the Discussion Questions
for each case history.
Activity 1: Snoring—Believe It or Not!
Procedure
1. Give each student a copy of Master 4.1, Snoring—Believe It or Not!,
and ask them to read it (these are all true stories).
2. Ask students to comment on their experiences with snoring.
Remind students that they have information from their own sleep
diary, as well as information from their class and other classes
around the country, that would allow them to gauge the incidence
of snoring among high school students using this supplement.
3. Give a copy of Master 4.2, Snoring Survey, to each student and
allow a few minutes for the class to answer the questions.
4. After the students have completed their surveys, discuss the
answers. Steer the discussion toward sleep disorders.
Sample answers to questions on Master 4.2, Snoring Survey.
Question 1. How common is snoring?
Student responses will vary. They might use the reported frequency of
snoring by their classmates from the sleep diaries as the basis for their
answer. In fact, everyone seems to snore a little. A poll taken several
years ago indicated that about 50 percent of the American population
reported snoring. Half of this group was habitual snorers. Snoring is
becoming increasingly common because fatigue and being overweight
aggravate the problem. Convey this information and that provided for
the other questions to set the stage for evaluating sleep disorders.
Question 2. What is snoring?
Students may simply respond that snoring is a noise made during
sleep. Try to elicit from them the idea that snoring involves breathing.
Snoring is an indication that air is not flowing freely through the
