1952 - Educational Science Film: Carbon Fourteen

1952 - Educational Science Film: Carbon Fourteen 01:39:45 Archaeological dig. Organic material found to be tested for age by Carbon 14 test. Breakdown of Carbon 14 explain. 01:40:33 Three men around drawing board in Science magazine office talking about wanting to explain carbon becoming nitrogen & back again. Animated drawing of atom w/ voice over talking about forming carbon dioxide & then being taken in to a plant. 01:42:15 Research laboratory w/ glass glass tube & part of axe handle to be tested after burning the sample. Tubes being filled. Back at magazine they talk about half-life which is an average of all the atoms decaying. Animated chart showing graph of change in atoms. Book listing half-life shown to two men by editor. 01:45:10 “...we expect to show some of its other uses...” “Carbon 14 is the queen of the tracers.” 01:46:06 Animated drawing of plant w/ carbon atoms going up stem to leaf, both radioactive & stable carbon atoms. Talk about how plants use carbon dioxide we might learn to make food in laboratory by duplicating the photosynthesis in plants. 01:48:01 Argonne National Laboratory & experiment in a sealed greenhouse where plants are grown in atmosphere where high level of Carbon 14. Dr. Scully doing the experiment that puts radioactive material in w/ the plants. 01:49:29 Setting up equipment to count the radioactivity of carbon in axe handle. Corn plant. The End. “Where there is life, there is carbon fourteen.” Instructional Film; Educational Film; Science; Scientific Theory; Atomic Energy; NOTE: One continuous minute sold at per reel rate.
