M the excellent solenos films produced by the Bell Co. for educational use Is one entitled "The Strange Cass of the Cosmio Rays," which i rated by educators throughout the country as being of elementary and secondary school levels. In it, Edgar Allen Poe and Charles Dickens favor the case of the cosmic rays as a winning detective story. Cosmio rays are found to be partioles originating in outer spaoe. A useful tool the cloud chamber is described in the course of the Among Going into the realms of tini- er bits of matter, some of the students built models of atoms to learn about how atoms are made of mainly three smaller Tbls.-pho- ne electrons neutrons. Ihese .models included the use of small sphere of clay tc represent the particles, and applicator stioks of varied lengths to give correot special arrangements for the par tides. Models of simpler atoms were more easily comprehended, although one student group decided to produce a model of a film, along with direotlons for uranium atom, the most oonplex making one.
