Houston, We Have A Problem

A WEBQUEST to support the NIH Curriculum Supplement Series- Sleep,

Sleep Disorders, and Biological Rhythms & the PsychSim activity on EEG & Sleep

StagesCreated by

Mr. Patrick MacLaughlin

For the first part of this activity, you will need to have completed the

Psychsim activity below. Be sure to identify answers to all slides before

moving on to the next slide.

PsychSim- Sleep Activity

Hypothetical Scenario- Next, you will use a hypothetical scenario to learn about the physiology and major stages of sleep.

- You will be able to determine what sleep is from this activity and what is going on physiologically during this time

Evaluating Sleep- As you navigate through the data for each astronaut, use the information in your textbook and other supplemental resources to evaluate the behavior of each individual.

-Complete Astronaut Telemetry Evaluation Form for each individual and answer the questions in complete paragraphs.

Astronaut Telemetry Evaluation Form

(Please print out completed form and submit with journal answers to questions that follow)

Astronaut

Sleep State

Useful data Data that was not useful

Astronaut Jordan

Astronaut Rodriguez

Astronaut Chen

After you have completed the activity, please reflect on the following questions,

and respond in paragraph form.

1. How can you distinguish between REM and NREM sleep? Between REM and wakefulness? NREM and wakefulness?

2. During a normal night’s sleep, we cycle through NREM and REM sleep several times. This cycling is called an ultradian rhythm because the cycle time is less than 24 hours. What can you conclude about sleep from this investigation?

3. Explain why REM sleep is sometimes referred to as Paradoxical Sleep

4. A friend tells you that she has been having terrible nightmares but can’t remember them when she awakens. In an effort to help her, you decide to spend the night observing her as she sleeps and awakening her when you think a dream is occurring. How are you able to detect that she is dreaming? On the basis of what you have learned form the Sleep Simulation, what would you notice about the occurrence and length of the sleep stages?

Based on your understanding of the modules that you’ve completed, complete the chart below, and submit this with your

journal answers. Physiological Process During NREM During REM
