GENERAL SCIENCE The following seven films were prepared by the Motion Picture Com- mittee of the National Science Teachers Association. LIST I ^EXPEDITION TO ANTARCTICA 2 reels-Color An excerpt from SECRET LAND (MGM) 20 minutes This excerpt presents highlights of the U. S. Naval expedition to Antarctica under the command of Admiral Richard E. Byrd. As the film opens, James D. Forrestal, then Secretary of the Navy, ex- plains the purposes of the expedition, and sequences show some of the preparations. When the fleet sets out, excellent maps explain the route and the goals of the exploration. Features of the trip to the South Polar Con- tinent include views of icebergs, whales, and penguins, and the passage through pack ice in the Bay of Whales. At Little America the film records activities such as setting up base camps and the capture of animal life including seals and varieties of penguins. Sequences of polar exploration by airplane reveal the discovery of a warm oasis near the South Pole. An Antarctic blizzard is filmed in all its fury. Animated maps and intelligent commentary summarize the results of the expedition. Study guides are available on request. *THE FIRST ATOMIC PILE An excerpt from THE BEGINNING OR THE END 2 reels-B&W (MGM) 17 minutes This film is a dramatization of the first test of the atomic pile at the University of Chicago in 1942. Many of the Manhattan Project scientists, such as Fermi and Compton, are portrayed. As the film opens, an observer from the U.S. Army arrives for the test. One of Dr. Fermi's assistants briefs the Army observer in a blackboard "chalk talk". This briefing clarifies and simplifies the test objectives for the film audience as well. With everything ready, including a "suicide squad" at the control rods, Fermi signals the start of the experiment. As meters whir and panel lights flash, the tension of the scientists is depicted. Finally Fermi cries triumphantly, "It multiplies!" as he terminates the test. As the film closes, the social implications of the project are introduced. Three of the scientists ask and receive permission to terminate their participa- tion since their religious scruples forbid their taking part in a munitions project. Teacher guides are available on request. 61
