Base Station Walk-Back
September 4, 2012


Mission Question:

How could you perform a physical activity that would improve heart, lung, and muscle endurance?

Being physically active is an important way to keep your muscles strong and your heart and lungs healthy. When shopping at the mall, touring a museum, or on the way to and from class at school, the lungs, heart, and other muscles benefit. They get stronger by being worked for long periods of time.


Crew Member Mission:

Students will:

  • perform a walk, progressing to 1600 m (1 mi) to improve lung, heart, and other muscle endurance.
  • record observations about improvements in this walk-back physical endurance experience using their lungs, hearts, and other muscles in their Mission Journal.
