A Classroom Savonius Windmill, William G. Hoffman
A Classroom Savonius Windmill, William G. Hoffman
Iowa Science Teachers Journal
The Savonius or S-rotor windmill was introduced to the United States in 1924. The powershaft is located in the vertical plane rather than horizontally as in the traditional bladed Stuart windmill. This has several benefits. The windmill does not need a wind direction seeking vane since it doesn't matter from which direction the wind is blowing. Also, power is available at the base of the mill rather than at the top of the tower. The Savonius mill is also less easily damaged by high winds than the traditional windmill.

Building Rapport And Changing Attitudes, Owen Primavera
Building Rapport And Changing Attitudes, Owen Primavera
Iowa Science Teachers Journal
During the past few years there seems to be a growing apathy on the part of high school students towards education. It seems that many are weaker in the basic skills of reading, writing and mathematics and could care less about their progress. Why do students feel this way about education and what can educators do to improve the situation?

What Is The Universe, And Why Is It Doing These Strange Things?, George L. Murphy
What Is The Universe, And Why Is It Doing These Strange Things?, George L. Murphy
Iowa Science Teachers Journal
1979 marks the fiftieth anniversary of a major advance in man's attempt to understand the overall structure of the physical universe. It was in 1929 that Hubble announced his discovery of the expansion of the universe. Ever since that time, astronomers have been finding evidence that the entire universe has been evolving, and have been attempting to adjust their view of the world accordingly.
Society, Science, And The Scientific Enterprise, Henry Veldhuis
Society, Science, And The Scientific Enterprise, Henry Veldhuis
Iowa Science Teachers Journal
Numerous developments in science and technology have moved man to the interfaces between science and government, science and religion, science and economics, and others. The necessity of functioning along these interfaces suggests that science education should include a commitment to the development of the scientific literacy necessary to understand the relationships between science and society.
The Need For A Philosophical Approach In The Teaching Of Science, Everett F. Morris
The Need For A Philosophical Approach In The Teaching Of Science, Everett F. Morris
Iowa Science Teachers Journal
In his paper, Slock (1977) commented upon a different view of what science is and how it operates. It has been my experience that prospective secondary science teachers are extremely deficient in this area. Perhaps, it is not a different view that is needed as much as a definite viewpoint that is needed.
New Audubon Society School
Iowa Science Teachers Journal
The National Audubon Society has established a special environmental education program which can serve as an accredited portion of any college, high school or graduate school student's curriculum.
Poorman's Litmus Paper

Purchase a head of red-purple cabbage. Cut up small pieces so that approximately a cupful of chopped leaves is obtained. Pour in enough water to cover the leaves and boil until the leaves turn colorless. Decant the purple liquid and store the liquid in a refrigerator for use.
Energy Concepts In The Iowa School Curriculum, Jack A. Gerlovich
Energy Concepts In The Iowa School Curriculum, Jack A. Gerlovich
Iowa Science Teachers Journal
Public school energy costs have soared nationally 150 percent since 1972-73. According to Educational Facilities Laboratories (EFL), that represented a $50 expenditure per student during the 1977-78 academic year (1). "School energy costs have doubled in the past 5 years .... Districts surveyed reported hikes ranging from 35 percent to over 400 percent, the average being 110 percent."
Wind Energy In Iowa, E. S. Takle
Wind Energy In Iowa, E. S. Takle
Iowa Science Teachers Journal
Wind and wind energy can be used as means for studying various topics in general science, mathematics, physics, and electronics courses. A brief background on wind energy and wind-driven electrical generators is provided. Suggestions are given for problems and projects on wind energy. These student activities can be used both for studying basic science and mathematical concepts and for developing an energy awareness.

Iowa Basic Skills Test, William Coffman
Iowa Basic Skills Test, William Coffman
Iowa Science Teachers Journal
'"As a professional in this business of testmaking, I am much more aware of the limitations of testing than most laymen. Achievement tests such as ours are designed as tools to help teachers do their jobs. Scores from them cannot be used as final judgments on anything - not children, not teachers, not schools and certainly not American education in general."

Iowa's Climate, Paul Waite
Iowa's Climate, Paul Waite
Iowa Science Teachers Journal
Living, as we are in Iowa, we are well aware of the effects upon our activities of the ever changing climate, which is, in itself, the summation of the even more variable daily weather. No one of us can escape the fact that our climate profoundly affects our energy, occupation, recreation, transportation, shelter, and food supply.

Iowa Tornadoes: Motivators For Science Teaching, John Stanford
Iowa Tornadoes: Motivators For Science Teaching, John Stanford
Iowa Science Teachers Journal
Iowa is located in the northern portion of the Midwestern "tornado belt." Students' natural interest in tornadoes and thunderstorms provide the alert teacher a ready-made introduction to science and the environment. The new paperback TORNADO -Accounts of Tornadoes in Iowa provides a wealth of information for the teacher, as well as reading material appropriate for students from upper-elementary through college.
Utilization Of Wave Energy, Walter R. Schmitt
Utilization Of Wave Energy, Walter R. Schmitt
Iowa Science Teachers Journal
When looking upon an aroused sea, many wonder how this seemingly large energy resource could be used. Inventive minds have gone to work on devices of all kinds - pumps and bellows, buoys, barges, and ramps, surface and subsurface siting, using alloys and plastics, etc. -generally based on mechanical or hydraulic principles. They would probably all work (if somebody would build them), but none thus far have been shown to do so profitably.
Some National Trends In High School Science Education And Their Influence In Iowa, Jack Gerlovich
Some National Trends In High School Science Education And Their Influence In Iowa, Jack Gerlovich
Iowa Science Teachers Journal
In August, 1978, a NEW sponsored National Assessment of Educational Progress (NAEP) report was issued entitled, Three Assessments of Science: Changes in Achievement 1969-77. The report indicated a 4.7 percent decrease in science achievement scores for 17 year-old high school students since 1969. During the same time period, 2.5 percent and 1.4 percent declines were reported for 13 and 9 year olds in science, respectively. Declines were observed to be greater in the physical than the biological sciences.
