Gauging Effects of Fatigue and StressPodcast Plus
David F. Dinges, PhD, is developing a test that will help astronauts to gauge fatigue and stress during long missions in space (podcast with lessons and more).
Gravity and BuoyancyLesson
Students compare the behavior of a water-filled plastic bag, both inside and outside of a container of water, to begin to understand environments with gravity and those with reduced gravity.
Hazards of Lunar DustPodcast Plus
G. Kim Prisk, PhD, DSc, talks about the health hazards of lunar dust (podcast with lessons and more).
Heart: Challenge of MicrogravityLesson
Students use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the body.
Muscles and Bones in SpaceLesson
Students learn how human muscles and bones change during space missions, and devise preventative solutions to help limit those changes.
Muscles and Bones: Center of GravityLesson
Students learn about center of gravity and how the body adjusts to the force of gravity to remain balanced.
