The Word Processor: A Tool Towards Improving Every High School Research Project, George E. O'Brien

Iowa Science Teachers Journal

Two important education phenomena are happening concurrently across the state of Iowa. First, it should be no surprise that the number of computers and computer science course offerings in high school is steadily increasing while the number of microcomputers in students' homes is also becoming greater. These factors have led to an overall increase in the number of high school students interacting with computers across the state. Second, feedback received from a variety of sources including state and regional science teachers' meetings, talented and gifted conferences (TAG), student science fair and symposia competitions and high school in-service visitations by Area …

Rock And Mineral Collecting In Iowa, Joseph H. Brown

Iowa Science Teachers Journal

The enthusiastic collector of rocks and minerals enjoys and practices a most interesting hobby. Nature has provided a free source of materials in many different localities, and the Midwest is no exception to this bounty. Success in finding a rare rock or mineral is limited only by the skill and perseverance of the collector. The natural beauty of many mineral, rock, and fossil specimens makes finding them a stirring experience. The value and rarity of these examples of nature's wealth makes the search for them a stimulating and profitable adventure.

The Learning Cycle Inquiry Strategy, Peter A. Rubba

Iowa Science Teachers Journal

In Carbondale, Illinois, Ms. Walters' 31 seventh graders enter the science classroom to find an array of materials and equipment on the tables. At each table are a balance, metric scale, graduated cylinder, and six cubical solids and six spherical solids; two of each solid type are made of aluminum, two of plastic, and two of steel; one of each pair of solids is larger than the other.

A Biological Light Meter, Dennis Sievers

Iowa Science Teachers Journal

High school experimentation during the study of botany generally includes observing photobiological processes. These might include photosynthesis, phototrophism and photoperiodism. Experiments with these processes often involve exposing a plant or plant tissue to a light source covered with a piece of colored cellophane or plastic. Measurement of the light intensity at a specific wave length is often necessary.

The Feeding Behavior Of The Giant Waterbug, Stephen W. Ziser

Iowa Science Teachers Journal

Ethology, the study of animal behavior; is a branch of biology too often overlooked in beginning biology courses. This is unfortunate since studying the behavior of living animals not only captures the interest and imagination of students more easily than other kinds of laboratory exercises but can also help to develop the skills of observation and description so fundamental to the art of science.

Demonstration Model Of An Organic Catalyst, Dennis Sievers

Iowa Science Teachers Journal

Introductory high school biology courses generally include a discussion of enzymes. Enzymes, commonly defined as biological catalysts, speed up biochemical reactions and are involved in nearly every biochemical process that occurs in a living organism. Many texts currently being used provide diagrams of enzyme action and a discussion of the "lock and key fit" of enzyme and substrate. Laboratory manuals accompanying these texts frequently indicate the usefulness of the chewed cracker experiment to demonstrate the presence and ·action of salivary amylase. Though this experiment uses an enzyme, it does not always accomplish the desired result - to enable the students …

Science Notes - Book News : "Science And Creation: Geological, Theological And Educational Perspectives", Robert W. Hanson

Iowa Science Teachers Journal

During the past few years the scientific community at large and the education community in particular have awakened to the public's concern about restoring traditional values in American society. The theory of evolution is seen by many Fundamentalists as responsible for the destruction of these values. Thus, in an attempt to restore this value system, a substantial part of the public has supported the movement to teach "creation science," which purports to show that a literal interpretation of the Genesis account of origins, including the notion that the universe is only a few thousand years old, can be supported scientifically.

Iowa's Driftless Area: Symposium, Daryl D. Smith

Proceedings of the Iowa Academy of Science

The 1983 Annual Meeting of the Iowa Academy of Science on Luther Campus in Decorah provided an excellent opportunity for considering the "Iowa Driftless Area," a region of scenic beauty and unusual scientific diversity. This rugged landscape dominated by bedrock has undergone weathering and erosion longer than any other region of the state. The term "Driftless Area" originated from an early geologic interpretation that a portion of northeastern Iowa had been untouched by Pleistocene glaciers.

Status Of Four Orchid Species At Silver Lake Fen Complex, Sara Carroll, Robert L. Miller, Paul D. Whitson

Proceedings of the Iowa Academy of Science

The native orchids Liparis loeselii and Spiranthes romanzoffiana inhabit hydric-mesic sapric histosol soils supporting three distinct fen vegetation zones at Silver Lake Fen State Preserve. Platanthera hyperborea and Cypripedium candidum primarily inhabit adjacent mesichydric aquoll mollisols supporting wetland and marsh vegetation. The fen orchids possessed shallow subterranean storage organs and perennating buds bathed in shallow water, while the non-fen orchids exhibited deep storage organs and perennating buds above a deep water table. Ramet census demonstrated all orchids possessed reproductive efforts greater than 90%, except C. candidum which exhibited 52% effort, probably due to low pollination. Genet analyses suggest L. loeselii …

Repeat Of A 1916 Bird Census In Northwestern Iowa, Peter E. Lowther

Proceedings of the Iowa Academy of Science

On 17 June 1982, a census of birds was taken on a section of farmland in Woodbury County, Iowa, to repeat earlier censuses in 1916 and 1926. A total of 41 species and 359 individuals were counted; 19 species were common to all three censuses. In general, between-year comparisons show great similarity in the bird life for the three censuses. Farmsteads, riparian and pastures (in this order) were the habitat classes with highest bird densities. The three most abundant species (House Sparrows, Barn Swallows and European Starlings) were found on farmsteads; the next two most common species (Western Meadowlark and …

Some Views On The Archaeology Of The Driftless Area In Iowa, R. Clark Mallam

Proceedings of the Iowa Academy of Science

The archaeology of the Driftless Area in Iowa encompasses a time frame extending from approximately 10,000 B.C. to Euroamerican contact. Researchers have defined a series of prehistoric adaptations for this period which can be conveniently grouped under two major modes of production: hunting/gathering and hunting/gathering-horticultural. By analyzing the evolution of these modes it may be possible to define prehistoric belief systems and the manner in which they functioned as significant components in the adaptation process. This combined scientific-humanistic approach may contribute toward a broader understanding of the prehistory of this region.

The Vegetation Of The Paleozoic Plateau, Northeastern Iowa, David C. Glenn-Lewin, Roger H. Laushman, Paul D. Whitson

Proceedings of the Iowa Academy of Science

The present vegetation of the Paleozoic Plateau region of Iowa is a fragmented representation of the original complex of oak-hickory forest mixed with more mesophytic forest, open oak savanna and hill prairie. Because of the topographic variation and the relatively cool, moist environment of the region, the forests are the best developed of those in Iowa, and show the greatest variation, including two types of alluvial forests (Salix thickets and alluvial hardwood forest), and several kinds of upland forests (Tilia, Acer, Quercus borealis, Q, alba and Pinus forests). These types represent points along a more-or-less continuous topographic gradient. Many of …

Report On Studies Of Streams In The Iowa Driftless Region, James W. Eckblad, Thomas G. Coon

Proceedings of the Iowa Academy of Science

The streams of the Iowa Driftless Area occupy old entrenched valleys, have high gradients, and transport cool waters flowing rapidly over rocky substrates. Water quality, overall, is relatively high when judged by either physio-chemical characteristics or stream communities. Distribution of aquatic biota largely reflects the habitats provided by spring-fed streams.

Comparison Of Otolith And Scale Age Determinations For Freshwater Drum From The Mississippi River, Timothy J. Goeman, Don R. Helms, Roy C. Heidinger

Proceedings of the Iowa Academy of Science

A comparative aging study was conducted using scales and otoliths from 123 freshwater drum collected in Pool 14 of the Mississippi River. Two independent readings by 2 investigators resulted in full agreement on ages assigned using otoliths, but only 64% agreement using the scale method. A final age was determined for the remaining scale samples based on the most commonly assigned age. However, there was no agreement on assigned ages for 12% of the scales examined. Otoliths were validated as an accurate method for aging freshwater drum by age frequency histograms for 3 consecutive years. The marked 3-year periodicity in …

A Floristic Analysis Of The Attached Diatoms In Selected Areas Of The Upper Mississippi River, Jeffrey B. Vansteenburg, Mark R. Luttenton, Ronald G. Rada

Proceedings of the Iowa Academy of Science

Attached diatom communities were studied along the border of the main channel of Navigation Pools 5 and 9 of the Upper Mississippi River. A total of 296 diatom taxa representing 42 genera were observed in the study. Approximately 52% of the taxa were common to both pools. The number of taxa was greatest in both study areas during the spring and fall and lowest during the summer. Coccones placentula var. euglypta (Ehr) Cl. usually accounted for ca 50% of the diatom density during the summer in Pool 5, whereas Cocconeis placentula var. euglypta and Navicula tripuntata var. schizonemoides (V …
