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? Jan 1970

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.


Open Letter To Science Teachers: Before You Lock The Door, Delma E. Harding Jan 1970

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 Jan 1970

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.


Issues In Elementary School Science Raised In Publication Jan 1970

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.


Elementary Science Projects And The Low Group Of Ninth Graders, Richard D. Mcvey Jan 1970

Elementary Science Projects And The Low Group Of Ninth Graders, Richard D. Mcvey

Iowa Science Teachers Journal

For many years it has been a common practice in junior high schools to group children according to their ability. In the science class, as well as in the other areas, this has had its advantages and disadvantages. To motivate the student in the low group is a different type of problem than to motivate the students of the average- or high-ability group.

The Iowa Academy Of Science As A Directing Influence In Science Education, Robert W. Hanson Jan 1970

The Iowa Academy Of Science As A Directing Influence In Science Education, Robert W. Hanson

Iowa Science Teachers Journal

The last decade was marked by drastic changes in the studied approach to teaching science and most school subjects. A whole new vocabulary of science education terminology appeared-the process approach, conceptual schemes, Hanson integrated science, audio-tutorial techniques, the multi-media approach, computer-assisted instruction. These and many other phrases can be summed up in the one word innovation, and many educators of the more traditional bent feel a bit uneasy and perhaps defensive about the extent to which innovation is lacking in their teaching.


Science Tomorrow, Robert S. Hansen Jan 1970

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: U.S. Army-Iowa Science, Engineering, And Humanities Symposium, Ronald D. Townsend Jan 1970

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.

Open Letter To Science Teachers: Society In The Science Classroom, Darrel Hoff Jan 1970

Open Letter To Science Teachers: Society In The Science Classroom, Darrel Hoff

Iowa Science Teachers Journal

In a speech given to a group of scientists and science educators last spring, Paul deHart Hurd repeated a remark made earlier by Bentley Glass that "a serious mistake has been made in the development of our national curricula in not stressing the social implications of science". Indeed this is true. You will search in vain for a reference to atomic weapons in the index of the Chem Study text. You will find no listing for hydrogen fusion weapons in the index of the PSSC text. DDT goes unlisted in the CBA index. You will find no reference to the …


Warning Issued Against Universal Use Of Lasers Jan 1970

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.


The Toxic Activity Of Main Trunk Wood From Diseased Dutch Elm Trees, Lyle C. Baugess, J. Lester Dalton Jan 1970

The Toxic Activity Of Main Trunk Wood From Diseased Dutch Elm Trees, Lyle C. Baugess, J. Lester Dalton

Iowa Science Teachers Journal

The Dutch Elm disease is caused by Ceratostomella ulmi (Schwartz) Buis (1); and, two types of elm bark beetles (9) are its vectors (3,4,9). Growth of the fungus occurs in the xylem tissue, which predominantly is concerned with conduction of water to the foliage. The spores and bud cells of C. ulmi are smaller than the elm wood vessels (1,2). C. ulmi, too, can be transmitted through root grafts.

A Consideration Of Student Understanding Of Science In Two Approaches To Bscs Biology, Harry F. Fulton Jan 1970

A Consideration Of Student Understanding Of Science In Two Approaches To Bscs Biology, Harry F. Fulton

Iowa Science Teachers Journal

The understanding of science by students is considered by science educators to be a worthwhile goal in the teaching of science. Attempts have been made to achieve this goal in the various curricula that have been developed, and the Biological Sciences Curriculum Study is one of these curricula. Several studies have been attempted to measure the understanding of science as a student outcome in a particular course such as BSCS Biology. In most studies the Test On Understanding Science (TOUS) (1) was the most common instrument used.

On The Trail Of The Decadent Polyglot, W. F. Hollander Jan 1970

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 …
