Educational Videos
Following his
time on Skylab, Dr. Owen Garriott produced a series of educational
videos, using science demonstrations performed on the station. The
following are links to the six-part video series.
Episode
1: Zero-G
Provides an introduction to the Skylab environment, a laboratory
above the Earth's atmosphere, effectively free from the Earth's
gravitational field. Dr. Garriott briefly explains the dynamics
of Earth orbit and the meaning of zero-gravity (weightlessness)
and shows brief demonstrations of phenomena that can be observed
only in zero-gravity.

Episode
2: Conservation Laws in Zero-G
Demonstrates the concept of angular momentum conservation
from the zero-gravity environment of the orbiting Skylab space
station. Illustrations in space are related to more familiar
examples on Earth. Also shows how the spinning motion of a
satellite changes to tumbling by dissipation of rotational
energy while angular momentum is conserved.

Episode
3: Fluids in Weightlessness
Explores numerous fluid phenomena in orbit, including surface
tension, cohesion, adhesion, and instability. Demonstrates
how collisions and splittings of liquid drops in orbital zero-gravity
can model systems ranging in size from an atomic nucleus to
a galaxy.

Episode
4: Gyroscopes in Space
Uses gyroscope demonstrations in the zero-gravity Skylab orbit
to explain both the principles and applications of gyroscopes
on Earth. The fascinating motion of gyroscopes is useful in
everyday life and essential to aviation and space travel.

Episode
5: Magnetism in Space
Opens with a montage of spectacular views of Skylab in orbit.
Reviews familiar aspects of magnetism, touches lightly on
its history, and explores the striking behavior of magnets
in weightlessness. rtsp://stream1.msfc.nasa.gov/magnetism.rm |

Episode
6: Magnetic Effects in Space
Demonstrates the effect of the Earth's magnetic field on small
bar magnets Dr. Owen Garriott carried up in Skylab. He explains
the tendency of magnets to line up with the Earth's magnetic
field and shows the oscillating motions of magnets in various
combinations and positions. Additionally, several demonstrations
are performed with a nut spinning in space. rtsp://stream1.msfc.nasa.gov/magnetic.rm |
