Presents an overview of man's use of resources in the states of Minnesota, Iowa, Missouri, Illinois, Wisconsin, Michigan, Indiana, and Ohio. Domestic and European migration and population trends of the region are indicated by animated drawings.

Indicates the basic principle of the standard plain milling machine. Each part of the machine is named and explained, and some elementary setups are demonstrated.
In addition to organic elements, living beings are necessarily composed also of inorganic elements such as calcium, iron and cooper. This program analyzes the ways in which these inorganic substances behave, and what their function is in maintaining life. Bulk elements, including calcium, sodium and phosphorous salts, serve as structural materials to build bones, link cells, and activate nerves. Trace elements, existing in minute quantities throughout the system, include the iron, cooper, nickel and zinc which are found in the blood, or in the chlorophyll of green plants. Experiments and demonstrations of the ways in which minerals behave in living things form part of the program.
Reports on excavations concluded at Nimrud, Iraq. Emphasizes the bronze gates, now in the British Museum, that were originally located in Balavat, near Nimrud. Points out that recent discoveries have shed light on various facets of ancient Assyrian civilization. (NYU) Kinescope.
Discusses the discovery of three elements predicted by Mendeleev. Demonstrates and explains the use of the spectroscope and of other methods in isolating elements. Revises Mendeleev's Periodic Table by adding the three new elements and rare gases. (KQED) Film.
Shows a variety of beaches and headlands, their contours, and evidence of a continuing interaction between land and water. Uses film sequences, photographs and demonstrations to illustrate the causes and effects of currents, waves, and tides. Explains their part in building up and destroying the shoreline. Tells how living organisms also protect and build up the land and at the same time help destroy it. Points out the destructive work of the rock-boring clams, urchins, and the contributions of kelp, other algae, and the tube worms in building up the beach area. Concludes with film clips of the octopus.

Back to the fair go the monkeys for the circus parade and Rico gets two tickets for the Circus.
Discusses the earth's only natural satellite, the moon. Uses charts, models, diagrams, photographs, and film clips to show and explain the moon's physical make-up, movement, size, density, phasing, and eclipse of the sun and the moon. Features James S. Pickering of the American Museum-Hayden Planetarium.
Two speakers discuss what the scientific community knew about the moon before the Apollo Program and what was learned from the missions from two different perspectives. One is from Jack Schmitt who worked on mapping the moon and planetary science before he became an astronaut who walked on the moon during the Apollo 17 mission. The other perspective comes from Hal Masursky who worked with the U.S. Geological survey and was involved in the selection of the landing sights on the moon.
