There are many partnerships in nature where two plants may help each other, or a plant and animal may mutually benefit one another, or where two animals may contribute to each other’s welfare. You will see on this program an example of each. The lichen, a common plant, looks like one individual, but really consists of two kinds of plants living together. You will see this story through the microscope. And you will see the story of cross-pollination, in which bees and insects take nectar from the flowers and in so doing transfer pollen from one flower to another.

Wind, heat, cold, and rain combine to weather the rocks and break them down. But the face of our earth is molded and the decayed rock carried away from one place and deposited in another mainly by water. The deposits laid down by water, wind, or ice produce after long periods of time and under pressure, rocks which are classed as sedimentary. You will see and learn how to distinguish some of the common sedimentary rocks; limestone, sandstone, shale, and conglomerate. Each of these sedimentary rocks is formed in a different way; limestone by chemical precipitations, sandstone by grains of sand cemented together, shale from beds of mud or clay pressed and cemented into thin layers, and conglomerate is made of gravel or pebbles of assorted sizes cemented together. You will be introduced to one of the most interesting features of sedimentary rocks -their fossils. These records of living things are guides to the history of life on the earth.
What happens when a rocket ship in space is struck and damaged by a meteor? Capt. Gell, a Navy expert on crew equipment, demonstrates the Navy’s full-pressure space suit for emergency escape from a shattered craft. Dr. Haber, an aerodynamic engineer who has made a thorough study of the theoretical problems of escape and survival far out in pace, explains the difficulty of making an individual descent into the atmosphere, on one hand, and of rescuing the stranded flyer in space, on the other. Dr. Herbert’s recommendation: the crew should ride the damaged vehicle back to earth --if anything remains of it.
