Keywords
polysomnogram, sleep stage, wave pattern, sleep disorder, sleep pattern, sleep
Key Concepts
Reading data from a unique source (polysomnogram), Compare/Contrast known and unknown samples of polysomnograms, Diagnosing sleep disorders
Process Skills Utilized
Observe, Analyze, Compare/Contrast, Apply and Infer
Intended Grade Level - 6-8
Objectives
Students will be able to:
Solve a “sleep mystery” involving polysomnogram analysis
Identify the stage of sleep and/or specific wave patterns, sleep disorders, etc.
Compare known (labeled) polysomnograms of patients with unknown (unlabeled) patient polysomnograms to infer the stage of sleep and/or specific wave patterns and sleep disorders found among the unknown polysomnograms
Observe how organ systems are interdependent
Activity Description
Students will apply the knowledge of polysomnograms they obtained in activity 3E, Polly Want a Somnogram? as they solve a sleep mystery. They will work like detectives to learn about patient sleep patterns. They will then compare and contrast labeled (known) samples of polysomnogram printouts with unlabeled (unknown) samples, much like work done by scientists who compare the electrophoresis patterns of the DNA of a known person with those of an unknown person to help identify the unknown person.

Activity Management Suggestions
You might want to make a class set of laminated “known” and“unknown” polysomnograms to save paper and to make the activity reusable from year to year.
After students have matched the “known” polysomnograms to the “unknown” polysomnograms, they will make some observations about the information on the polysomnograms. Things to point out with the students using the known samples of polysomnograms [I through XII.] include:
As patients move from Stage 1 sleep to Stage 4 sleep, compare and contrast the changes in the EOG, EEG and the thoracic and abdominal changes.
Patients in REM sleep have a unique EOG pattern.
Point out that unique patterns such as k-complexes, spindles and saw tooth may occur more often in the stages of sleep listed in the chart on the following page, but can also occur in other stages as well.
Modifications: Careful selection of group members to allow students with special needs to fully participate in the activity.
Extensions: Students can conduct a self-study of their sleep patterns and the effect they have on reaction time over a longer period of time.
