How can we correct that situation? By letting students know of the opportunities in the chemical profession. By the time I had completed a year of chemistry as a high school student, I was aware of the use of chemistry in the cement industrv (bv studvine the reactions of chemis- try when we studied thk alkaline earth elements), the steel industrv (when studvine the processes of iron smelting and . .. reactions or iron), chrwing gum, the s u l f ~ ~ r industry, etc.

A single high school course would he more valuable and enjoy- able for the student if they had already had an effective introduction to the joys of the science early on. We must teach science a t every level.

For two weeks last summer. several elementarv school children in grades 3-6 participated in an enrichment pro- eram desiened to develoo. nurture. and challenae them hv " providing itimulating, hands-on rxperirncrs. Thi~ohjectives uf therhrmisrrv oorrion ot rhis prorram were fourfold: r l J to introduce the %dents to the-rudiments of the scientific method, with particular emphasis on observation, (2) to help the students discover, via experimentation, some fundamen- tal aspects of chemistry, iucluding various schemes for the classification of matter (metals versus nonmetals, com- pounds versus mixtures, acids versus bases), the difference between physical and chemical changes, and the physical states of matter, (3) to convey that chemistry is relevant to everyday life, and (4) to kindle a spark of interest in chemis- try. Each day, the students spent approximately 30 minutes in a classroom settine. disrussine the previous dav's experi- ments, sharing the results of tLeir hbmework assignment, and listenine to an introduction to the current experiments. The remain& 90 minutes were spent in the iahoratory.

Household items were used whenever possible, hoth in the experiments and for the homework, to assist the students in grasping the relationship of chemistry to their lives. For example, table salt, iron nails, and copper BB's were used to prepare mixtures; solutions of baking soda, vinegar, and 7- Up were used in the acid-base experiments; physical state changes were illustrated with ice and dry ice. Nylon and polyurethane polymers, as well as aspirin and other esters, were oreoared so the students would recognize the value of s y t h r t i r chemicals and rhe chemiral i n d k y . At the con- clusion of the iirst week, chemistry "magic" was perlbrmed, hoth by the instructor and the students. i he magic show was expressly designed to meet the fourth ohjective cited above. From the students' responses, that ohjective was met.

We received favorable feedback from students and par- ents alike. As instructors. we were oleased with the outcome of the course. The students were well behaved and were not hesitant to participate in discussions. Especially enjoyable was the enthusiasm and excitement the students brought to class. We heartily recommend a program of this sort for elementary students. Interested instructors are wel- come to write for more details, including example laboratory manuals and lists of reagents.

Two Cultures. One Problem: Educating and Informing the Non-technologist and the

Technologist E. E. Fllby We~tinghouse Idaho Nuclear Company. Inc. Idaho Falis, ID 83403

Ever since the study and development of science and tech- nology became a recognized set of disciplines, there have been communication problems between the practitioners and nonpractitioners of these disciplines. C. P. Snow defined the ~rohlems in terms of "Two Cultures" and hiehliehted - what he saw as the more significant aspects. For some time after his lecture, the debate often became fragmented over details: Are there only two or are there many "cultures"? However, the substance has remained basically unchanged: Those who have a more-or-less technological bent often can- not, or will not, communicate effectively with those who do no t have such a bent, and vice versa. The problems arise hoth in the educational systemand in our public information channels. Yet hoth groups have the same basic problem: All must function where technological wonders and problems are inextricably intertwined with every aspect of society.
