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.
More Snow Jobs, Paul Joslin
More Snow Jobs, Paul Joslin
Iowa Science Teachers Journal
On the first day of snow, when the attention of children is obviously distracted from normal classroom procedures, have them bundle up and go outside. Once outside, have the students follow you in a line and form a circular path. You can then use the circle formed in the snow, to teach or review concepts associated with motion, time, direction, fractions and geometry.

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.

Investigating Iowa's Weeds, Paul G. Jantzen
Investigating Iowa's Weeds, Paul G. Jantzen
Iowa Science Teachers Journal
The term "weed" is often defined as a plant out of place. A. C. Martin has complained that this definition reflects human bias and that pest plants are out of place only with respect to man's immediate purpose. In nature's scheme, they often serve useful functions such as providing food for wildlife throughout the growing season and covering barren soil, thus preventing soil erosion. Judging from their competitive success with many so-called desirable species, they are anything but out of place.

Ias-Aaas Incremental Investigative Grants For High School Students, Lynn W. Glass
Ias-Aaas Incremental Investigative Grants For High School Students, Lynn W. Glass
Iowa Science Teachers Journal
In an attempt to encourage Iowa high schools to provide support for investigative science activities, the Iowa Academy of Science, with the financial support of the American Association for the Advancement of Science, has created an Incremental Investigative Grant Program. These grants, beginning with the current school year, are available for appropriate scientific investigative activities by high school students working under the sponsorship of a science teacher.
Intelligent Zinc
Iowa Science Teachers Journal
Recently, Professor Adon A. Gordus of the University of Michigan has been directing a study of more than 800 well-documented hair samples. Using atomic absorption spectroscopy and neutron activation, his study has uncovered some interesting correlations between academic performance and trace metal content of hair.
The Anti-Science Syndrome, Arthur Koestler
The Anti-Science Syndrome, Arthur Koestler
Iowa Science Teachers Journal
The average person will be reluctant to admit that a work of art is beyond his level of comprehension; but he will, in the same breath and with certain pride, confess his complete ignorance of the principles which make his radio work.

Patriotic Phenolphtalein, Joe Moore
Iowa Science Teachers Journal
To illustrate the "patriotic nature" of phenolphthalein, prepare a dilute solution by dissolving 0.1 gm of phenolphthalein in 100 ml of ethyl alcohol and dilute with 50 ml of water.
Will It Work In Iowa?
Iowa Science Teachers Journal
The embankments of many Austrian highways today show on both sides of the road a new installation: game-warning reflectors which are designed to divert beams from car headlamps into the adjoining countryside. The basic idea for the installation of the reflectors has been derived from the studies of the Institute of Comparative Behavior Research in the Austrian Academy of Sciences, which concentrated on the effect on animals of "eyes" and "eye dummies."

Holography: Capturing The Third Dimension, Michael Timmons
Iowa Science Teachers Journal
Holography, the three-dimensional recording of interference patterns on film has unlimited possibilities in the fields of science, art, technology, and media. Three types of holograms, the "flat" or plane, circular, and white light, are presently being produced successfully and inexpensively in the high school situation. The novelty of holography arouses curiosity while allowing the student to experience the application of interference phenomenon.
