There have been some major changes among the nation's schools in the past 20 years. These include (a) appearance of paraprofessionals; (b) new instructional technologies; (c) varying levels of desegregation; (d) federal funding accompanied by federal control; (e) larger school districts; (f) more informal instructional arrangements; and (g) unionization of teachers.


A Laboratory Excercise In Gas Chromatography For High School Students, Bernard Hermanson Jan 1981

A Laboratory Excercise In Gas Chromatography For High School Students, Bernard Hermanson

Iowa Science Teachers Journal

Gas chromatography is a sophisticated tool for the isolation, identification and quantification of chemical compounds. The purpose of this exercise is to introduce the principles of gas chromatography to first year chemistry students. For the exercise, students inject their own chemical samples, estimate the purity of these samples by counting the number of peaks on a print out, measure retention times for the materials observed, and compare the "r" values to those of known substances.

Comparison Of Perceptions Of Major Problems In Science Education, Jack Gerlovich, Robert Yager Jan 1981

Comparison Of Perceptions Of Major Problems In Science Education, Jack Gerlovich, Robert Yager

Iowa Science Teachers Journal

The National Science Foundation has stimulated much thought, analysis and assessment concerning the discipline of science education. The three status studies of K-12 science education have attracted national attention and study (Helgeson, 1978; Stake & Easley, 1978; Weiss, 1978). Nine professional groups have had committees analyze the results of these studies from the perspective of their respective memberships. The National Science Foundation also awarded another large research grant to the University of Colorado called Project Synthesis. This project, under the direction of Norris Harms, has attempted to synthesize the status study reports and the recent data from the National Assessment …

Do Reading Ability And Sex Differences Make A Difference In Science Achievement?, Sharon Wadsworth, Lynn Glass Jan 1981

Do Reading Ability And Sex Differences Make A Difference In Science Achievement?, Sharon Wadsworth, Lynn Glass

Iowa Science Teachers Journal

Educators, parents and politicians of late have all been concerned with test scores, especially declining test scores. Much debate has taken place concerning whether, in fact, there has been a decline in the level of student performance or, rather, whether there has been a change in the population of students taking a given test. Many explanations have been tendered concerning reasons for the possible decline in test scores. This study was concerned with science scores from one Iowa high school. Specifically, this study sought to determine if there was a decline in science test scores and to determine what variables …


Potential New Iowa Multi-Use Crops For Oils And Hydrocarbons, Russell A. Buchanan Jan 1981

Potential New Iowa Multi-Use Crops For Oils And Hydrocarbons, Russell A. Buchanan

Iowa Science Teachers Journal

Many green plants contain, on a dry weight basis, more than 5 percent oil plus hydrocarbon that is not concentrated in storage organs. In these plants, oils and hydrocarbons (botanochemicals) are distributed throughout major plant tissues often as the major component of a latex. Although there has been little past interest in processing whole plants for botanochemicals, there is now great interest in these new and renewable sources of raw materials and energy. Various plant species are being regarded as potential "gasoline trees", as possible domestic sources of natural rubber and plastic, as new sources of industrial feedstocks or even …


Quick Crystals, Sil Crespo Jan 1981

Quick Crystals, Sil Crespo

Iowa Science Teachers Journal

When teaching about minerals, there is no way that you can omit the topic of crystals. Usually, we either go to our mineral cases and take out examples of crystals to pass around, or we grow our own. The only problem with these methods is that both take time. With the former, we are looking at crystals "after the fact." With the latter, we lost the interest of some students because it takes too long to grow crystals from a solution.


A Use For A Throwaway, Dennis Kingery Jan 1981

A Use For A Throwaway, Dennis Kingery

Iowa Science Teachers Journal

A small vial or test tube plugged with cotton makes a very satisfactory watering device for caged insects. A significant drawback, however, is the difficulty in preventing the tube from rolling whenever the cage is moved. Setting the tube in a lump of clay is often suggested, but the clay soon becomes quite soiled.

A Tool For Assessing, Implementing, And Evaluating Science Curriculum (K-12) For Iowa Schools, Jack Gerlovich, Gary Downs, George Magrane

Iowa Science Teachers Journal

In the fall of 1977 the Iowa Department of Public Instruction (DPI) began to receive many requests for assistance in developing coordinated science programs. Local schools faced with aging science materials, economic constraints, increasing pressure from publishing companies, and decreasing student reading and computing skills needed guidelines for assessing, implementing and evaluating their science curriculum. The purpose of this tool is to provide such assistance.

Help Keep Hawks In Hawkeye Land, Steve Duecker Jan 1981

Help Keep Hawks In Hawkeye Land, Steve Duecker

Iowa Science Teachers Journal

Many people have watched a hawk soar on a warm spring day. As the hawk turns lazy circles in the sky, he is riding currents of air that push him up. Not much hunting is done from this soar. Hawks are equipped with strong feet and sharp claws called talons. These are for capturing and killing their food. Their hooked beak is used to tear the food up for swallowing. Hawks have ear openings and can hear fairly well. The eyes of the hawk are about eight times more powerful than a human's and are especially built to detect movement …


Due To Technical Difficulties Jan 1981

Due To Technical Difficulties

Iowa Science Teachers Journal

The worst thing about a burning issue is that no one can smell it until there's a fire. We all spend our days deeply engrossed in ourselves, noses pressed to the grindstone. Who can see anything in that position? Then, something ignites a spark - and, suddenly, everyone calls "Fire!"

Iowa Science Teachers Journal

At the University of Northern Iowa we have four so-called "Current Curricula" courses - one each in junior high science, biology, chemistry, and physics. Each is preceded in the teaching degree programs by a course called "Orientation to Science Teaching." Most students who take these Current Curricula courses are juniors or seniors and have had at least part of their professional sequence in the College of Education.
