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.

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.

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 …

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.

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

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.

The Vascular Flora Of Gitchie Manitou State Preserve, Lyon County, Iowa, Delmar Vander Zee

Proceedings of the Iowa Academy of Science

Gitchie Manitou State Preserve in Lyon Co., Iowa is unique for its relict prairie and quartzite flora. The vascular flora inventoried in 1974-1976 includes 328 species from 66 families. Seven plant communities are described: native prairie, plants of quartzite outcrops, secondary succession grassland, Jasper Pool woods, plants of Jasper Pool mudbank and littoral zone, Big Sioux River flood plain woodland, plants of disturbed areas. Species reported by others are noted and discussed.

Society, Science, And The Scientific Enterprise, Henry Veldhuis

Iowa Science Teachers Journal

Numerous developments in science and technology have moved man to the interfaces between science and government, science and religion, science and economics, and others. The necessity of functioning along these interfaces suggests that science education should include a commitment to the development of the scientific literacy necessary to understand the relationships between science and society.

The Need For A Philosophical Approach In The Teaching Of Science, Everett F. Morris

Iowa Science Teachers Journal

In his paper, Slock (1977) commented upon a different view of what science is and how it operates. It has been my experience that prospective secondary science teachers are extremely deficient in this area. Perhaps, it is not a different view that is needed as much as a definite viewpoint that is needed.

A Checklist Of The Vascular Plants Of The ''Whiting Triangle'' In Central Wisconsin, Robert W. Freckmann

Proceedings of the Iowa Academy of Science

The vascular flora of the ''Whiting Triangle'' - a 30 acre (12 ha) area of semi-wild land within the Stevens Point, Wisconsin urban area has been observed and collected since 1964. Four hundred seventeen taxa have been collected at this site, including typical species of central Wisconsin as well as rare or otherwise notable taxa for the state. A checklist of the flora is presented.

Thirty-one species in 10 genera of foliose and fruticose lichens are reported for Linn County, including 3 lichens previously unreported for Iowa: Cladonia nemoxyna, Physcia luganensis, and Physcia rubropulchra. Information on substrate and abundance of each species is included.

Birds Of Some Iowa Wetlands In Relation To Concepts Of Faunal Preservation, Mitlon W. Weller

Proceedings of the Iowa Academy of Science

Forty-one species of birds nested in the prairie-wetlands complex of Dewey's Pasture during the period 1962 to 1974. Numbers of pairs and nests were recorded annually for the ducks and other waterbirds that dominated the avifauna, but observations on terrestrial species were less detailed and only frequency of occurrence data are presented. These data on bird use of a relict pothole area demonstrate the dynamics of bird populations in relation to habitat conditions. Abundance and diversity of waterbirds were positively correlated with increasing water depth. Problems of conserving typical avifaunas in small wetlands units surrounded by intensive agriculture are discussed …
