Body Systems: Surviving Extremes

The following questions appear onscreen in the video. Feel free to integrate them into your lesson plan as needed.


 
Part I
Questions to consider before watching the video:
  • How do changes in air pressure affect our bodies underwater and at high altitudes? As you watch the program, note the potential risks facing deep-sea divers and high-altitude mountain climbers.
  • What precautionary measures do professionals take to prepare their bodies for these extremes?
Questions to consider after watching the video:
  • Although the human body cannot adapt to extreme pressure, we can take measures to prevent sickness. How can we avoid the bends or high-altitude pulmonary edema?
  • Compare and contrast the measures deep-sea divers and mountain climbers take to avoid these life-threatening conditions.
Part II
Questions to consider before watching the video:
  • Gravity is a force that our bodies have adapted to on Earth. What happens when that force is eliminated?
  • Consider the challenges astronauts face by spending time in zero gravity.
  • As you watch the program, pay attention to the long-term physical and social effects of living in outer space.
Questions to consider after watching the video:
  • Surviving in outer space for long periods of time is difficult on the body and mind. Describe the physical and mental challenges of living in space.
  • What type of person do you think is best suited to living in outer space?
