All Episodes

  • Plants and Life On Earth (#101)

    Explore the inner part of Earth’s solar system, starting with the Sun and its structure. Fly over and experience the contours of Mercury, Venus, and Mars, and learn how gravity and momentum keep the planets orbiting around the Sun elliptically, as first revealed by Kepler. [14 minutes]

  • Tornadoes: How They Form (#103)

    In order for viewers to grasp the size of Earth’s galaxy, this program first lays out the concept of light years. Comparisons with earthly time frames helps viewers understand that the light from distant stars is actually elapsed cosmic time. [14 minutes]

  • Severe Weather: Temperature, Motion, Moisture (#104)

    Experience the cosmic wonder of a universe expanding at phenomenal rates, as discovered by Edwin Hubble in the 1920's. [13 minutes]

  • Solar Systems: Inner Rock Planets (#105)

    This program will help viewers grasp the significance of water as never before. Without this bond of three atoms, life, in its current form, would not exist. [14 minutes]

  • Solar Systems: Outer Gas Planets (#106)

    Experience the world of plants as the essential foundation of life on earth. Their beauty is shown, as are their functions, such as providing food, clothing, and shelter. [14 minutes]

  • Stars, Light Years & The Milky Way (#107)

    Find out why the solid-seeming earth is actually a changing body, constantly destroying and rebuilding itself. Tectonic plates’ movements are clearly demonstrated as the source of these alterations through exciting live-action and computer graphic images. [13 minutes]

  • Galaxies & The Expanding Universe (#108)

    The linear chain of volcanoes around the Pacific Ocean is called the "Ring of Fire." Expanding upon the theory of plate tectonics, this program uses live-action and computer-graphic images to show how plates constantly collide or pull apart, causing molten rock beneath the surface to well up from time to time, forming volcanoes. [14 minutes]

  • Volcanoes & The Ring of Fire (#109)

    Severe weather’s sources are the same as those for all weather patterns. The sun's energy, along with the earth's rotation, is demonstrated graphically as the driving force behind circular wind motion. [14 minutes]

  • Plate Tectonics & Earthquakes (#110)

    Why is the southern Middle West of the United States particularly prone to tornadoes? In spring, the collisions of still-frigid winds from Canada with the warm upwelling breezes from the Gulf of Mexico create thunderstorms. If these collisions accelerate, supercells of even faster rotations occur, creating more upwelling and circulating, with hail and a funnel forming. [14 minutes]

  • Floods, Fronts & The Water Cycle (#111)

    Powerful weather and the water cycle's part in it are explored together in this production. The cycle often results in warm and cold air masses battling against each other along boundaries or fronts. [14 minutes]
