Lesson 2 Organizer: Print Version Activity 1: Houston, We Have a Problem What the Teacher Does Explain that this lesson uses a hypothetical scenario to investigate physiology and the major stages of sleep. • Ask the class to reflect on their responses to the statement from Lesson 1, “Sleep is time for the body and brain to shut down for rest.” (False.) Show the transparency of Master 2.1, Astronaut Scenario, and read it to the class. Procedure Reference Page 73 Step 1 Page 73 Step 2 Give each student a copy of Master 2.2, Astronaut Telemetry Evaluation Form, and single copies of Masters 2.3, 2.4, and 2.5, which contain the telemetry data for the three astronauts. • Explain that these data are sufficient to tell if an astronaut is awake or asleep, and if asleep, whether in NREM or REM sleep. Give each student a copy of Master 2.6, Sleep Medicine Reference Manual. • Explain that it is a resource to help them interpret the astronauts’ data. Instruct students to evaluate the data for each astronaut and enter their conclusions on Master 2.2, Astronaut Scenario. Pages 73–74 Steps 3 and 4 Page 74 Step 5 Page 74 Step 6 = Involves using a transparency. = Involves copying a master. 77 Student Lesson 2
Sleep, Sleep Disorders, and Biological Rhythms Discuss the sleep state of each astronaut and ask, • Which data are useful for making such determinations? • How can we distinguish between REM and NREM sleep? • How can we distinguish between REM and wakefulness? • How can we distinguish between NREM and wakefulness? Explain that during the night, we cycle between NREM and REM sleep several times. • Introduce the concept of an ultradian rhythm. • Ask the class, What can you conclude about sleep from this investigation?
