Science Notes - Outlook Is Underway!
Iowa Science Teachers Journal
The first Outlook class of Iowa educators began course work on Monday, June 5, 1983. A total of 320 educators from all parts of the state were enrolled in the eight week-long, in-service training programs. Seven of the week-long sessions were at the Springbrook Conservation Education Center north of Guthrie Center and one week was scheduled for the campus at the University of Northern Iowa at Cedar Falls.

Man Or Mouse?
Iowa Science Teachers Journal
When testing a new compound (Chlorfenvinphos) for killing ectoparasites on dogs, Vernon Brown of the Shell Toxicology Lab in England found the LD50 differences between species to be enormous. For rats, the LD50 value was 12 mg per kilogram of ordinary feed, for mice 100-200 mg, while dogs proved indestructible at 12,000 mg.

Human Evolution, Robert D. Seager
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 …
Teaching Nuclear Issues
Iowa Science Teachers Journal
The Nuclear Information and Resource Service has just published several new publications designed to help educators teach about nuclear weapons and nuclear power.
The Nuclear Arms Race And The Science Curriculum, James Cottingham
The Nuclear Arms Race And The Science Curriculum, James Cottingham
Iowa Science Teachers Journal
This paper proposes some ideas about the appropriateness and value of the study of nuclear weapons in the school curriculum in general and the science curriculum in particular. I will discuss some ideas that have been tried in this area by me and by others as well as some proposals that could be tried in the future. In addition, I will reflect on things we should be doing as science teachers in regard to nuclear weapons issues.
Human Skin Temperature And Biological Clocks: A Laboratory Exercise For Physiology Students, K. A. Langley, G. E. Folk Jr.
Human Skin Temperature And Biological Clocks: A Laboratory Exercise For Physiology Students, K. A. Langley, G. E. Folk Jr.
Iowa Science Teachers Journal
A simple laboratory experiment is described, consisting of taking the mean temperature between two fingers of human subjects. The results from comparing male and female students is presented. The change in skin temperature over four hours is documented, to demonstrate the importance of doing standardized experiments at the same time of day.
Diatoms (Part V): Ecology, James Hungerford
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.
Energy Crunch
Iowa Science Teachers Journal
Chop up some spinach, throw in some fat, add water, sunlight and a few other chemicals, and you may end up with a recipe for easing the energy crunch. At the Michigan State University laboratory of biophysicist Dr. H. Ti Tien , these ingredients are used to make a device for generating electricity directly from sunlight.
Paleobotany, Dennis Sievers
Paleobotany, Dennis Sievers
Iowa Science Teachers Journal
Paleobotany is the study of fossilized plant material, and includes the study of fossilized spores and pollen. Many plants during the Pennsylvanian Period were fossilized during coal formation in permineralizecl peat deposits, forming coal balls. Coal balls contain numerous fossils of plant fragments, including pollen and spores that are preserved in meticulous detail. The tools and processes required for the study of microfossils in coal balls are inexpensive and can be found in most high school laboratories. Two methods of coal ball study will be described in this paper. The first method involves the study of microfossils through the preparation …

A Multiple Evaporator For General Chemistry, H. I. Feinstein
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.
Spinach
Iowa Science Teachers Journal
Ever wonder why spinach is supposed to be so good for you? Popeye will tell you it's the presence of healthy quantities of iron. But did you know that every gram of spinach also contains manganese, strontium, zinc, uranium and europium - in fact, at least 27 trace elements?
