Examines the third step in producing "SH" in isolation: blowing air across the high blunted tongue. Progresses from the "Presentation Stage" through the "Imitation Stage" to the "Production Stage" using two teaching devices.
Begins the in-depth teaching of "SH" by teaching the first step: learning to blunt the tongue. Follows the learning process through the "Presentation Stage" to the "Imitation Stage," after the teacher's evaluation of the pupil's main error in blunting. Demonstrates two teaching devices.
Continues work on the first step of learning "SH", blunting the tongue, at the "Imitation Stage." Shows the pupil achieving a better approximation of pulling the tip into the body of the tongue, and finally achieving correct blunting by keeping the tongue blunted and forward.
Depicts a second pupil beginning to learn "SH" through in-depth teaching, starting with Step 1--blunting--at Face A of the speech model. Examines the pupil's blunting error (pulling the whole tongue back) and his first approximate correction of the error, achieved through shaping.
Continues the discussion of infant feeding begun in MAKING A FORMULA and introduces a mother and a baby-sitter who discusses with a doctor some of the problems and practices in baby-sitting. Points out the desirability of a pre-sitting meeting of mother, sitter, and baby.
Shows how the Navajo weave their rugs. Includes the following different operations: sheepshearing, carding of the wool, spinning by hand, setting up the loom, making the dye, dyeing the yarn, close view of weaving technique, and finishing the weave.
Uses drawings and dissected specimens to compare the nervous systems in hydra, planaria, earthworms, and grasshoppers and shows the response of a paramecium, euglena, amoeba, hydra, and planaria to stimuli. Points out the spinal cord, spinal nerves, and parts of the brain in a freshly dissected pig and makes comparisons between the parts of the brain in frogs, birds, cats, and humans. Illustrates through still and animated drawings the basic elements of the neuron and the pathway of the nerve impulse during a reflex arc.
Uses animation to illustrate the versatility of the triangular shape. Shows a single triangle dividing, re-dividing, and re-forming into colorful representations of symmetrical and asymmetrical shapes, including stars, cubes, rhombuses, and parallelograms. Concludes with the multitude of forms returning to the basic triangle.
Presents a factual summary of the basic United Nations Organization program for world security in 1945. Clarifies the structure, analyzes the plans, and shows how, by joint action to solve relief, food, and money problems, the world can be rid of conditions that breed war.
Uses photomicrography and time-lapse sequences to reveal the research technique of nuclear transplantation. Shows how nuclei are transplanted from donor body cells into activated eggs.
