A Word About Wood, H. M. Barnes
A Word About Wood, H. M. Barnes
Iowa Science Teachers Journal
The annual per capita consumption of wood in the United States is 65 cubic feet. This is equivalent to seven trees, ten inches in diameter and fifty feet tall for every American.
Corn To Alcohol, A. C. Haman
Corn To Alcohol, A. C. Haman
Iowa Science Teachers Journal
The combination of critical fuel shortages and zooming oil prices have led to the possibility of converting corn to an alcohol fuel, a process that has been known for some time. The benefits offered by an alcohol-fuel industry are substantial, among a few are: the fuel source is renewable each year; domestic alcohol fuel reduces dependence on oil imports; and fuel alcohol burns clean reducing pollution. The economic impact to the state economy is obvious.
The Earth's Gravity Field, Robert S. Carmichael
The Earth's Gravity Field, Robert S. Carmichael
Iowa Science Teachers Journal
Curiously, books in Iowa have more "gravity" effect in them than even TIME suspected. In fact, due to gravity effects in the State, a) the same book would weigh less in Des Moines than it would in the town of Anita, 50 miles (80 km) to the west. b) a quick way to lose weight is to travel from the north-central Iowa town of Blairsburg to the nearby town of Wellsburg.

Iowa Diatoms: Part Ii (Preparation), James Hungerford
Iowa Diatoms: Part Ii (Preparation), James Hungerford
Iowa Science Teachers Journal
This is the second in a series of articles on Iowa diatoms. The first article appeared in the Dec. 1978 issue of the Iowa Science Teachers Journal and dealt with the collection of diatoms in the field. After collecting diatoms in the field and labeling the collection jars properly, you must now prepare the diatoms for study in the laboratory. This article outlines the basic techniques for preparing diatoms for laboratory study.
Acetate Peels From Iowa Carbonate Rocks, Wayne I. Anderson, Mary Hogan
Acetate Peels From Iowa Carbonate Rocks, Wayne I. Anderson, Mary Hogan
Iowa Science Teachers Journal
Iowa's rock record is noted for its abundance of carbonate rocks. These carbonate rocks, limestones and dolomites, contain interesting textural features and an abundance of fossils. The fossils can often be removed from the rock matrix and studied. The fossils can also be studied in cut and polished slabs of rock or by making thin sections of the rock. Thin sections are prepared by cutting a thin slice from the rock and gluing the slice on a glass slide. The rock slice is then ground-down with abrasives to a thickness of .030 mm., covered with a coverslip, and studied with …

Warning - Strong Oxidant!, Howard Lyon
Warning - Strong Oxidant!, Howard Lyon
Iowa Science Teachers Journal
Even the most casual survey of the uses of hydrogen peroxide would demonstrate that it is considered to be one of the safest oxidizing reagents available. Hundreds of useful commercial applications employ dilute H202 - water mixtures for bleaches, bubbling agents, mild cleansers and other gentle oxidation processes. The use of hydrogen peroxide in the teaching laboratory is recommended as far safer than the use of the pennanganates, nitrates, dichromates, chlorates and perchlorates which might otherwise be employed. The 3% solution is used to clean open cuts or employed as mouthwash. Analytical laboratories, employing higher concentrations, would …
Energy Kits
Iowa Science Teachers Journal
Under a new policy announced by the Charles Edison Fund, the famous Edison Teaching Kits (used effectively in more than 13,000 classrooms) are again available to teachers and school librarians.
Decapods Of Iowa (Part Ii), Gary Phillips
Decapods Of Iowa (Part Ii), Gary Phillips
Iowa Science Teachers Journal
Since the classic work of T.H. Huxley in 1880 on The Crayfish, decapods have been widely used in teaching elementary zoology, as well as for research along more advanced lines. Traditionally decapods have been used to demonstrate various characteristics typical of arthropods in general. Among these are the open circulatory system, ventral nervous system and segmentation.
Solar Energy Packets

DOE Solar energy Curriculum for Grades 7-12. This program consists of 43 solar energy activities arranged in five packets.
Energy Quiz
Iowa Science Teachers Journal
America, with about 6% of the world's population, consumes about 30% of the world's available energy. The average American citizen consumes about seven times the energy of other world citizens. But what does the average citizen know about this energy that is used in a too casual manner?

Is There A Greater Role For Insects As Food?, G. R. Defoliart
Is There A Greater Role For Insects As Food?, G. R. Defoliart
Iowa Science Teachers Journal
The world food deficit has resulted in an expanded effort to find new sources of protein. With significant research efforts directed toward development of oilseed, leaf, fish and single cell concentrates, it is surprising that insects have been almost totally overlooked. They are a natural food for many kinds of animals and they are used widely as food by some human populations, especially in the tropics where they help compensate for the general deficiency in animal proteins, fats and calories. The few biochemical studies done to date indicate that insect protein is of high quality.

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.

Beyond The Metre (Part I), Richard S. Tompkins, Vincent N. Lunetta
Beyond The Metre (Part I), Richard S. Tompkins, Vincent N. Lunetta
Iowa Science Teachers Journal
This article is the first in a series discussing the wide spectrum of metric units. Metric education programs typically avoid measuring force, energy, and other physical quantities. Specialized units like the joule and pascal, however, will be appearing more and more frequently. How many Americans can confidently interpret a label rating a light bulb in lumens? This series of articles for the general reader will review the history of the metric units, the rationales behind their definitions and the fine points of their usage. Examples and exercises will relate the special units to every day experiences. This initial article will …
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."

Tetrahymena: Cell For All Seasons, Eugene C. Bovee
Tetrahymena: Cell For All Seasons, Eugene C. Bovee
Iowa Science Teachers Journal
Certain protozoa have often been the cellular animals of choice for research and teaching in the past 100 years. In 1926, Asa Schaeffer (20) placed "the amoeba" at the pinnacle for animals that serve as primary research tools, along with the dog and the frog. Paramecium (one or more of its species) and Euglena (one or more of its species) are other protozoa (the latter, also an alga) well-known and oft-employed in both teaching and research. In the past 40 years, however, another protozoan has gained prominence in research, equalling - even superseding - the three mentioned above. Its generic …
Safety In Iowa Science Programs: A Status Report, Jack Gerlovich, Frank Starr
Safety In Iowa Science Programs: A Status Report, Jack Gerlovich, Frank Starr
Iowa Science Teachers Journal
School science laboratories are active sites of learning. They may also be areas of potential danger from fire, explosives, caustic chemicals, poisons, noxious fumes, and projectiles. Science teachers are charged with the responsibility of establishing an environment in which students shall have relevant, practical science experiences. In addition, certain segments of the subject matter will require that students develop particular attitudes, knowledge, and skills. Inevitably students will periodically be exposed to potentially dangerous situations.
