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.
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.

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.
Acs Study

The Iowa Science Teachers Journal Prior To 1976, Robert E. Yager
Iowa Science Teachers Journal
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.

Holography: Capturing The Third Dimension, Michael Timmons
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.

Excellence In Science Teaching Award Program Prior To 1976, David Mccalley
Iowa Science Teachers Journal
The Iowa Academy of Science has a long and distinguished record of encouraging improvement in science education within Iowa's public and parochial schools. Evidence of this may be seen in its support of the Iowa Junior Academy of Science, The Iowa Science Teachers Journal and various Academy committees having as their major concern the promotion of science education. In past years, the Recognition and Awards Committee of Iowa Academy of Science has functioned to identify outstanding science and mathematics teachers in Iowa.
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 …

Come To The Health Fair, Owen Primavera
Come To The Health Fair, Owen Primavera
Iowa Science Teachers Journal
During the spring of 1975 the Milford High School Science Club planned to sponsor a Health Fair which would involve free medical services for the community. The fair was preceded by a health survey which attempted to administer a questionnaire to all residents of Milford, Iowa. The object of the survey was to determine the immunization status of the community in order to assess the need for conducting a Health Fair.
