Survey Of In-Service Needs Of Iowa Science Teachers, Timothy Cooney, Darrel Hoff Jan 1983

Survey Of In-Service Needs Of Iowa Science Teachers, Timothy Cooney, Darrel Hoff

Iowa Science Teachers Journal

National concerns about science education have suggested a number of factors which are contributing to what is now being called a crisis. One such factor is that colleges and universities are producing fewer certified science teachers, even as many science teachers are leaving the classroom to pursue other employment. A second factor is that the average age of the science teacher is increasing and many teachers have not continued to update their training. A third factor; which may be a result of the first two, is that the number of secondary students taking science and the number of courses they …

Collecting Reptiles And Amphibians For Classroom Use, Donald J. Perschau Jan 1983

Collecting Reptiles And Amphibians For Classroom Use, Donald J. Perschau

Iowa Science Teachers Journal

The advantages of living organisms in the classroom are well known to biology and elementary teachers. Live animals and plants spark interest, provide color and movement, can be used as teaching materials, and can generally improve the classroom environment. Organisms commonly found in classrooms include plants from the genera Coleus, Dracena, Philodendron, and many others, and animals which are often small mammals or perhaps tropical fish. Seldom does one find more primitive vascular or non-vascular plants, invertebrate animals, reptiles or amphibians. It has been my experience that these organisms have much to add to the classroom and …

The Identification Of Unknown Bacteria, Steve Ziser Jan 1983

The Identification Of Unknown Bacteria, Steve Ziser

Iowa Science Teachers Journal

A major activity of most college level introductory microbiology courses is the identification of one or more unknown bacterial species. The ways suggested in many lab manuals for identifying bacteria are often unorganized and difficult to follow. In addition, the huge volume of information often required to make a diagnosis may overwhelm beginning microbiology students who are largely incapable of weighing the importance of many of the tests in trying to decide how to best proceed with the identification. Microbiology manuals too often overlook the fact that identification is an orderly process of moving from general characteristics to more specific …


Human Evolution, Robert D. Seager Jan 1983

Human Evolution, Robert D. Seager

Iowa Science Teachers Journal

A common characteristic of humans is a desire to know their roots. This is evident not only in the tracing of family ancestries, but in the excitement about and attention given to the study of the roots of our entire species - the study of human evolution. We have, over the past few million years, evolved from an ape-like ancestor to modern Homo sapiens. Like evolution in general, the fact of human evolution is as firmly established as anything in science. There are, however, differences among scientists concerning details of this process. In this paper I will give an historical …

A Multiple Evaporator For General Chemistry, H. I. Feinstein Jan 1983

A Multiple Evaporator For General Chemistry, H. I. Feinstein

Iowa Science Teachers Journal

Many experiments require a hood clue to the evolution of hazardous fumes. One such experiment involves the use of nitric acid in the determination of combining ratios of certain metals, e.g., tin and oxygen. Where large classes are the rule, as in general chemistry, and the number of fume hoods is limited, the progress of the class is slowed considerably if individual set-ups are used.

Diatoms (Part V): Ecology, James Hungerford Jan 1983

Diatoms (Part V): Ecology, James Hungerford

Iowa Science Teachers Journal

Diatoms are found in a wide variety of habitats. Fossil evidence suggests that diatoms are of relatively recent geologic origin in comparison to other algal groups. The oldest known fossil specimens come from the Jurassic Period (Vinyard 1979). Centric diatoms are predominant in the more ancient strata and also are the predominant forms in present day oceans (Vinyard 1979). Fossil diatoms are used to locate oil strata and water strata, to record the movement of glaciers and to reconstruct paleoecological environments.

Science And Math Teachers: A National Survey Of Supply And Demand, Trevor Howe Jan 1983

Science And Math Teachers: A National Survey Of Supply And Demand, Trevor Howe

Iowa Science Teachers Journal

Total enrollments in Iowa public schools, K-12, have declined. Total enrollments have declined by 130,116 students in ten years. The projected enrollments are expected to drop 31,444 students in the next five years. Obviously the implication is a reduction in the number of teaching positions at both the elementary and secondary levels over the next several years. However, current data indicate that the science and math teacher supply is decreasing more rapidly than student enrollment.
