Iowa Science Teachers Journal

A listing of several science-related meetings during December 1970-April 1971.

The Oregon Science Teacher

Iowa Science Teachers Journal

The May, 1970, issue of TOST will be devoted to science humor, and will feature in excess of a hundred 'bits' of the bizarre, witty, irreverent, burlesqued, parodied, and off-beat side of science.

A Description Of An Experiment Involving The Use Of A Modified Drum-Type Spherometer For Measuring The Rate Of Weathering, Darrell D. Young

Iowa Science Teachers Journal

For the teacher who is interested in teaching a unit on weathering, the cemetery may provide unlimited amounts of data. As an exercise in weathering, a measuring instrument was devised and tested by the author on tombstones in the Buffalo area. The instrument used and the results of the test are described as follows.

Science Tomorrow, Robert S. Hansen

Iowa Science Teachers Journal

A few years ago the rate of production of scientists and (not too surprisingly) the rate of production of scientific articles was doubling every ten years. Really new science was coming out at a tremendous rate, generating major new areas such as solid state physics, molecular biology, radio-astronomy, and major breakthroughs such as the cracking of the genetic code, the discoveries of the transistor effect, of pulsars, and quasars, of techniques of stereospecific syntheses, of ultrasensitive methods of compound detection, identification, analysis, and structure determination, and of new fundamental particles in profusion.

Open Letter To Science Teachers: Before You Lock The Door, Delma E. Harding

Iowa Science Teachers Journal

Before closing textbooks and locking classroom doors for the summer, check on several things to help make your teaching more coordinated and meaningful when fall comes. Make out a tentative schedule for next year's classes. Decide what units to teach and approximately what length each is to be. Include a list of materials you plan to use for each unit. This means chemicals, slides, demonstrations, experiments, models, audiovisual aids, tape recordings, glassware, and anything else you expect to use. Have everything ordered or available for use, so there are no disappointments or holdups when you start teaching again.

Innovation In Science Education In Australia, Richard P. Tisher

Iowa Science Teachers Journal

There are many similarities in the type of science education provided in Australia and in the United States. Teaching methods, for example, range from the traditional textbook-oriented approach to a laboratory, inquiry-oriented one. Also similar issues related to science education are being debated. Two areas of concern are the preservice education of science teachers and curriculum development. It is in this last mentioned area that the greatest innovation has occurred.

On The Trail Of The Decadent Polyglot, W. F. Hollander

Iowa Science Teachers Journal

At the risk of beating a dead horse to death, I desire to add my lick. Students are not adequately trained to communicate in science, and the objective-type test is not helping. When linguistic fluency is equated with drooling in one's beard, and semantics is some sort of erotic deviation, one must not be surprised to learn that etymology is the study of incests. Most of the kids have become aware that mini means small, and that lunar means moon, and we should be grateful for such small advances, but the slippage in other areas is less cause for a …

Professor Says Marijuana Should Not Be Legalized

Iowa Science Teachers Journal

Grass, pot, jive, mary jane, or Texas tea. By whatever name you know it, marijuana should not be legalized, claims Dr. Joseph Benforado, assistant clinical professor of medicine and a physician at the University of Wisconsin Health Center.

Resume Of Physics Section Meeting During Fall I.S.E.A. Convention Program, Henry J. Biere

Iowa Science Teachers Journal

The two major topics dealt with in the physics section are of major concern to physics teachers.

Science And Social Change, Milton O. Pella

Iowa Science Teachers Journal

The meager period of time we call "ours" in the vast continuum from creation to dissolution has but one constant and that constant is change; our time is one of unprecedented change.

If Cyclamate Is Banned, Should Hundreds Of Other Products Be Removed From Market?

Iowa Science Teachers Journal

If cyclamate is banned on the basis of the few tests performed so far, then hundreds of other products should also be removed from the daily market. This is the opinion of Drs. Stanley L. Inhorn, director of the Wisconsin State Laboratory of Hygiene, and Lorraine F. Meisner, instructor of preventive medicine at the University of Wisconsin.

Identifying And Growing Biochemical Mutants Of Arabidopsis Thaliana, Sujit K. Dhar

Iowa Science Teachers Journal

Beadle and Tatum (1945) irradiated bread mold fungus, Neurospora spores, with X-ray and isolated biochemical mutants by their inability to grow in minimal medium. They identified the defective pathways by finding a particular amino acid, vitamin, or nucleotide which, being added to the medium, remedied the defect.

Open Letter To Science Teachers: U.S. Army-Iowa Science, Engineering, And Humanities Symposium, Ronald D. Townsend

Iowa Science Teachers Journal

U.S. Army-Iowa Science, Engineering, and Humanities Symposium - In September, 1969, letters announcing this year's symposium and preliminary applications were sent to high school principals in Iowa and western Illinois. This year through the cooperation of the Iowa Academy of Science, initial letters and applications were also sent directly to the science teachers whose names were on the academy's mailing list. Included in the letter was a brief sketch of symposium activities and goals. The science teacher applications included nominations for student research papers and nominations for student symposium participants other than those applying to give papers.

Far-Nix And Lar-Nix Diesected, Charles J. Ellis

Iowa Science Teachers Journal

High school teachers do a wonderful job. This observation is of long standing and particularly true when one considers the "handicaps" under which these teachers operate. They not only must give of themselves and of their time, but each must be the disciplinarian, father-confessor, and big-buddy of the students. They must cope with school boards and parents, take tickets and usher! For all their expertise in these many areas, we on the "outside" thank these teachers.

Unusual Ph.D. Program Supported

Iowa Science Teachers Journal

Support of an unusual graduate program in science and mathematics education is provided by a National Science Foundation grant of $29,700 awarded today to the University of California at Berkeley. Known as "SESAME" (Search for Excellence in Science and Mathematics Education), the recently established program leads to a Ph.D. Its aim is to offer students the opportunity to combine advanced training in one of the natural sciences or mathematics with the pursuit of central interests in science education.

Warning Issued Against Universal Use Of Lasers

Iowa Science Teachers Journal

Enthusiasm for use of lasers in air pollution studies is being tempered by evidence that they should not be regarded as a universally useful yardstick, a University of Wisconsin physicist says.

Science Teachers' Knowledge Of Sound Theory, Jerry Underfer

Iowa Science Teachers Journal

J. W. Warren has written a book recently which gives a critical review of mistaken ideas which are conveyed by physics textbooks and overlooked by physics teachers. Although Warren doesn't consider the area of sound to any extent, the situation is analogous. As he points out, errors and misleading material which are published for years while books pass through several editions gravely mislead students.

Parks Suspend Entrance Fees Pending Congressional Action

Iowa Science Teachers Journal

The Department of the Interior's National Park Service has suspended entrance fees to park areas normally entered by automobile pending Congressional action on restoring the Golden Eagle Passport, an annual fee system which expired last March 31.

Open Letter From The President, Lena Keithahn

Iowa Science Teachers Journal

Recent mailings from the Executive Secretary of the Iowa Academy of Science to every science teacher in Iowa should encourage each one of us to become an active part of the Iowa Science Teachers Section of the Academy and to become well informed about every phase of the program. By becoming involved in the Iowa Academy you can enjoy all the benefits of membership as well as the advantage of working with science teachers throughout the state.

The Need For Sex Education, R. J. Vanden Branden

Iowa Science Teachers Journal

There is no shortage of information and misinformation about sex education; however, it is difficult to determine which information is based upon more than personal bias and experience. Educators profess to educate children in those aspects of behavioral change which are based upon the needs of the students. The assumption is that if a need exists that is not otherwise being met, the schools must satisfy that need. Is sex education such a need?

A Comparison Of Achievement In Biology In An Individualized And Group Approach To Bscs Biology, Harry F. Fulton

Iowa Science Teachers Journal

In January of 1970 the author completed a study at The University of Iowa. In general the purpose of the study was to compare student outcomes as a result of exposure to an individualized and a group approach to teaching the Biological Sciences Curriculum Study (BSCS) course.

Issues In Elementary School Science Raised In Publication

Iowa Science Teachers Journal

At which point does a child understand science? Should elementary school science serve his immediate interests or future needs? These are some of the questions raised by D. C. Ipsen, author of Issues in Elementary School Science, the latest publication of the National Science Teachers Association.

Iowa Section Of Aapt Will Meet In April

Iowa Science Teachers Journal

The Annual Spring Meeting of the Iowa Section of the American Association of Physics Teachers will be held Saturday, April 25, 1970, at Grinnell College.

How We Raise Clean, Healthy Amoeba Proteus, Eugene C. Bovee, Sandra C. Thompson, Mercedes L. Acuña

Iowa Science Teachers Journal

We so frequently use Amoeba proteus for observation and experimentation in our classes in Cell Structure and Function, and Physiological Protozoology at the University of Kansas, that it has been necessary to avoid buying the many needed cultures from any of the major biological suppliers. Consequently, we have had to devise a reasonably reliable method of our own to culture that amoeba.

The Effects Of Catalytic Or Promoter Oxides On The Brin Process, John L. Moriarty Jr.

Proceedings of the Iowa Academy of Science

Future generation high altitude aircraft will require logistics independent, on-board oxygen generation systems. In an attempt to meet this challenge the eighty year old Brin Process,

BaO + ½O₂ ↔ 750°C ↔ BaO_{2 ,}

was re-examined using a laboratory breadboard model. The influence of eighteen oxides as reaction promoters was studied and the results of forty admixture experiments are evaluated. Observed behavioral trends can be explained based on geometric and electrochemical factors. An equal molar mixture of La₂O₃ and BaO does lower the reaction temperature about 100°C, increases the reaction rate, and improves the oxygen …
