Iowa Science Teachers Journal

Dr. John D. Dodd, Professor of Botany and Plant Pathology at Iowa State University, has just published a new botany text suit able for a one term course in general botany. Course Book in General Botany, published by the Iowa State University Press, emphasizes descriptive rather than the physiological aspects of plants.


Aging Iowa Trees, Roger Q. Landers Jan 1977

Aging Iowa Trees, Roger Q. Landers

Iowa Science Teachers Journal

How old is this tree? Or that one? Unanswerable questions to most people, unless they are there when it started growing, but with proper techniques, equipment, and a bit of skill (or luck), it is not so difficult to determine the age of a tree. Because trees grow in girth by the addition, each year, of a layer of wood just inside the inner bark, these layers can be counted when they are clearly exposed. We usually see the layers exposed as rings on the surface of a stump, hence the study of aging trees is referred to as "tree-ring" …

Iowa Assist: Outreach Foci, Daniel S. Sheldon

Iowa Science Teachers Journal

Iowa-ASSIST is a statewide program for improving science teaching in Iowa. ASSIST is an acronym for Alternative Strategies and Services for Improving Science Teaching. Iowa-ASSIST developed from several NSF-Supported Academic Year Institute programs for preparing science supervisors which were conducted in Iowa. It was established as a formal program in 1973. The program operated during 1973-76 with support of approximately $600,000 from the National Science Foundation (NSF).

Iowa Plan For The Statewide Use Of The Computer For Education, Dean D. Crocker

Iowa Science Teachers Journal

The timely information now available in the application of high speed computer techniques to education may benefit students, school administrators, supervisors and other decision makers alike. Science teachers and students may find assistance through the use of instructional and career guidance applications. Education administrators, supervisors, teachers and other community and state planners can benefit by using the available data in projecting alternative solutions for critical planning issues.

Where there is much desire to learn, there of necessity will be much arguing, much writing, many opinions; for opinion in good men is but knowledge in the making.


An Inquiry Into Tides, Darrel Hoff Jan 1977

An Inquiry Into Tides, Darrel Hoff

Iowa Science Teachers Journal

Classic earth science textbooks present a rather generalized treatment of the topic of tides, but to the majority of mid-westerners the descriptions are largely without intrinsic meaning because of the lack of firsthand experience with marine tides. The suggestion contained herein provides a vicarious experience with tides for landlocked Iowans that will hopefully stimulate discussion resulting in an improved understanding of tidal phenomena.

Some High School Biology Electives, James H. Meyer, Robert Nelson Jan 1977

Some High School Biology Electives, James H. Meyer, Robert Nelson

Iowa Science Teachers Journal

Cedar Falls High School, for many years, offered a science curriculum composed of traditional biology, chemistry, and physics courses. The percentage of students taking science courses began declining in the late 1960's, reaching a low of 573 students (out of approximately 1,500 students) in the 1972-73 school year. Since all science courses offered at the school were elective.it was concluded that some adjustment in course offerings was in order if a greater percentage of the student body was to be reached. As a result of the efforts of the science staff, five new biology courses were developed and subsequently introduced …

Eighteen Years Of The Hawkeye Science Fair, Dean Stroud

Iowa Science Teachers Journal

Pre-planning for the first Hawkeye Science Fair began in 1958 when representatives of the Iowa Medical Society, the Des Moines Register and Tribune Co., and Drake University met to discuss the feasibility of organizing to sponsor a science fair. Later, the Scanlon Medical Foundation was added to the list of sponsors. The first fair was held in the spring of 1959.

The Hazards Of Window Peeping, Sondra Waltz Jan 1977

The Hazards Of Window Peeping, Sondra Waltz

Iowa Science Teachers Journal

When studying the development of a chick embryo by opening up an egg every few days to observe its growth, two problems arise. The first is that every egg does not begin its development at the same time or proceed at the same rate. Second, the disposal of the embryo after it has been studied (especially after taking on the appearance of a mature chick) is awkward. The psychological impact upon the child in killing the poor little chick is difficult to assess and, for some students, may even destroy the educational objectives of the whole study.


Bioassay And Corn Coleoptiles, S. Lane Wilson Jan 1977

Bioassay And Corn Coleoptiles, S. Lane Wilson

Iowa Science Teachers Journal

In the 1930s, Dr. F. W. Went and R. Bonner conducted investigations into the factors regulating cell elongation in plants and their subsequent effect on plant growth. These studies eventually led to the isolation of a plant growth hormone called auxin. Auxin was finally identified chemically as indole-3-acetic acid or IAA.

Reflections Of A Life Fellow, James Hungerford Jan 1977

Reflections Of A Life Fellow, James Hungerford

Iowa Science Teachers Journal

There was a Hungerford in the first graduating class of Iowa State University. One of my grandfathers was a former Iowa College president, founder of Blue Cross, president of one of Iowa's larger hospitals and held a doctorate in Humanities. My other grandfather was a farmer and all of his five sons and two daughters were either educators or professors or farmers or combinations thereof. With these roots, I have a feeling of pride in my heritage, a deep-seated affection for the State of Iowa and an unshakable belief in the value of science and education.

My career as a physics teacher began in 1938. This was the year that I was assigned to teach my first physics class. My undergraduate field was biology. I needed something to compensate for my very inadequate background in physics.


Self-Paced Experiences: A Participant's Daily Log, Jay B. Thorniley Jan 1977

Self-Paced Experiences: A Participant's Daily Log, Jay B. Thorniley

Iowa Science Teachers Journal

As part of my educational requirements, prior to student teaching, at the University of Northern Iowa, I was required to participate in a self-paced classroom. The following is a daily log of my experiences in a class of 18 students in the course, Self-Pacing Biology Experiences (SPBE), at the Malcolm Price Laboratory School. These notes, taken over six weeks, should prove helpful to those teachers considering adoption of self-pacing programs.

The Potential Of Wild Plants As Food Resources, J. R. K. Robson Jan 1977

The Potential Of Wild Plants As Food Resources, J. R. K. Robson

Iowa Science Teachers Journal

The modern world is so full of scientific wonders that we often forget to look back in history and recognize landmarks that were just as significant as the discovery of the transistor, penicillin, or the laser beam. The history of our present day food is a prime example of a phenomenon that is considered to be too mundane to be taken seriously. Yet, thousands of years ago man made a scientific discovery concerning food that made possible the growth of settlements that became our cities.
