Dr. D. C. Anderson, the State Archeologist has just released the following description of the project.
Amoebas That Can "Blow Your Mind", Eugene C. Bovee
Amoebas That Can "Blow Your Mind", Eugene C. Bovee
Iowa Science Teachers Journal
Until the mid-1950's it was assumed by biologists and physicians that the only amoeba that endangered human comfort is the one that infects the digestive tract, causing amoebic dysentery in the susceptible and unwary tourist exposed to its more virulent varieties. Although that one, known to biologists as Entamoeba histolytica, sometimes escapes to the other parts of the body to cause sores and disturbances, it rarely causes death of its host, being a generally "well-behaved" parasite.
In This Corner: Career Education, Steven K. Halstead
In This Corner: Career Education, Steven K. Halstead
Iowa Science Teachers Journal
Often science educators feel that career education belongs in the Industrial Arts or Vocational Agriculture or Home Economics classroom but not in the Science classroom. Since Sputnik, science educators have been selling their course offerings by talking about the vast technological society in which we live and how the job market needs scientifically literate workers. Too often, however, these same educators view career education only as the production of pre-professional scientists. They seem not to include nurses, laboratory technicians and other applied fields in science vocations.

The planets will move as they always have whether we adopt a geocentric or heliocentric view of the heavens . . . but, the behavior of man is not independent of the theories of human behavior that men adopt.

While flying from Minneapolis to a convention on the west coast we observed that it was becoming dark outside even though we took off in daylight and were flying west toward the sun. We asked ourselves the question, "How fast should we be flying to 'keep up with the sun'?"

In Defense Of Ambiguity, Eugene C. Bovee
In Defense Of Ambiguity, Eugene C. Bovee
Iowa Science Teachers Journal
If I recall correctly, one of the first adjectives I learned as a freshman in college was ambiguous. I do not remember looking it up in any dictionary when I learned it after the first mid-term tests. It was then enough for me to learn that if a professor's test-questions were deemed "ambiguous," I could excuse my failure to answer test-questions accurately and blame the professor for having hidden from me what I should have learned and understood. In my years since, as a professor, I find that the freshmen and upper classmen and even graduate students are still sophomoric …

What Good Is An Old Spear Point?, Duane C. Anderson
Iowa Science Teachers Journal
Not long ago I came in contact with a young learner named Kelly who was fascinated by Indian artifacts. He had amassed a sizable collection and wanted to find out more about his discoveries--things like how old the items were, what they were used for, and by whom. These and other questions need to be answered, not just for Kelly, but for people of all ages who live in Iowa, for we all have a right to a knowledge of the past.
How To Recover Microfossils From Common Iowa Rocks, Wayne I. Anderson
How To Recover Microfossils From Common Iowa Rocks, Wayne I. Anderson
Iowa Science Teachers Journal
The rocks of Iowa contain a great abundance and variety of fossils. Megafossils, those fossils of sufficient size to be seen with the unaided eye, are abundant in many Iowa quarries and roadcuts and are therefore common in most fossil collections of Iowa teachers and students. Unknown to many, however, is the fact that the abundance and diversity of fossils in the microscopic range is equally great. This article describes techniques by which microfossils can be recovered from sedimentary rocks, illustrates and describes some common microfossils and suggest some localities for collecting samples of microfossils.
Scientific Bulb Snatching, V. G. Devonald
Scientific Bulb Snatching, V. G. Devonald
Iowa Science Teachers Journal
The subject of plant morphology is frequently considered a boring topic by both teacher and pupil, and consequently given a somewhat inadequate treatment. Several reasons can be adduced for this unfortunate neglect of a field of knowledge which is, in fact, particularly suitable for intensive study in schools. An unnecessary restriction of teaching types (e.g., broad bean, crocus, sweet pea, etc.) may evoke bored familiarity, or the subject may be given such a superficial treatment that no morphological analysis is achieved and interest is not aroused. Often, a grossly teleological approach is adopted in teaching morphology and many unproven assumptions …

Science Foundations: A Science Program For The Non-Science Major, James A. Shymansky
Science Foundations: A Science Program For The Non-Science Major, James A. Shymansky
Iowa Science Teachers Journal
The Science Foundations program at the University of Iowa consists of a sequence of general science courses designed specifically for the non-science student. The program is unique both in course content and instructional strategy. Recognizing that student backgrounds and needs differ greatly between the science and non-science major, the Foundations program is offered as an alternative to the traditional lecture-based science courses. Whereas the lecture-based courses emphasize the recall and application of factual material, Science Foundations stresses problem- solving strategies based on laboratory experience. Consequently, practically all of a student's time is devoted to "hands-on" activity with problems in the …

Iowa - Upstep: A Program Overview, Vincent N. Lunetta
Iowa Science Teachers Journal
Over the past five years the program for science teacher preparation at the University of Iowa has been in the process of gradual evolution. The changes have been stimulated by a grant from the National Science Foundation, by teachers, and by science educators. Many teachers in the state of Iowa have played a major role in the development of the current program. In the current UPSTEP program the professional education sequence has become more thoroughly integrated with the student's total program and incorporates a series of clinical experiences in the schools.

Aerosols And The Atmosphere, Darrel Hoff
Aerosols And The Atmosphere, Darrel Hoff
Iowa Science Teachers Journal
In recent months concern has been expressed about the effect of certain aerosol sprays on the protective ozone layer of the atmosphere. This is a current environmental issue and it seems an appropriate topic for discussion in the high school science classroom. Like many environmental issues, the aerosol issue is not as clearly defined as is sometimes presented in the general media, and it should therefore be approached with an open mind by both teachers and students.

The Iowa Association of Science Teachers (IAST) was formed in 1907 for "promoting interest in science teaching in secondary schools." This organization functioned for several years as a strong and influential organization with membership in all of the largest secondary schools in the State. Various special reports and newsletters served as the "journal" for this early organization.
