Stimulating Interest In Iowa Secondary School Science, Jack Gerlovich, Joe Moore
Iowa Science Teachers Journal
America, today, is a highly technological society, based heavily upon knowledge of scientific concepts and principles. Without knowledge in basic science, and its processes, living with and understanding technology cannot be accomplished. More specifically, alienation of the lay public from the scientific community and scientific endeavors may result.

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."
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.

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.

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.

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?
