The Distribution Of Amphipods In Southeastern Minnesota And Their Relation To Water Quality And Land Use, James A. Muck, Raymond M. Newman

Journal of the Iowa Academy of Science: JIAS

The distribution of the amphipods Gammarus pseudolimnaeus and Hyalella azteca was determined from 97 designated trout streams in Minnesota, along with temperature, conductivity, and nitrate levels. Streams were classified into 4 land use/geology groups. G. pseudolimnaeus was found in 11 counties and at 123 of 168 sites in 83 of the 97 streams sampled. Hyalella azteca was found in 7 counties at 26 sites m 21 streams. Spearman rank correlations showed a high degree of correlation between nitrate (range: 0-11 mg N/L), conductivity (range: 325-870 μS/cm), and geology. The relative abundance of G. pseudolimnaeus was negatively correlated with nitrate, geology …

Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker

Journal of the Iowa Academy of Science: JIAS

Fens are peatlands which are dependent on groundwater discharge to provide nutrient enrichment. Fens are found in a variety of landscape positions and in most Iowa landform regions. This paper presents a classification system for Iowa fens based on landscape position, stratigraphy, and hydrologic factors. Iowa fens can be separated into six categories: 1) fens along valley wall slopes; the groundwater source for these fens is sand and gravel buried between glacial tills (inter-till); 2) fens in hummocky topography on the northwestern margin of the Des Moines Lobe landform region; the water source is sand and gravel buried within glacial …

The University Of Iowa Museum Of Natural History: An Historical Perspective, George D. Shrimper

Journal of the Iowa Academy of Science: JIAS

The 132-year record of UIMNH essentially mirrors historical and on-going trends in related institutions. As scholarship grew in the natural sciences during the 19th century, natural history museums became centers for scientific research. A "Golden Age" of museum-based expeditionary work and taxonomic research was marked at UI by the careers of curator/naturalists Calvin, Nutting, Macbride, and Shimek. Systematic biology and paleontology thrived with the accumulation of extensive collections. De-emphasis of "natural history" studies followed after 1920-30 with a concomitant growth in cellular and molecular biology. In seeking new directions and financial support, many museums, including UIMNH, shifted emphasis to public …

Science Notes - Field Testers Needed For Biology Education Project, Jonna M. Higgins

Iowa Science Teachers Journal

The National Association of Biology Teachers (NABT) is seeking 40 life science and biology teachers to field test hands-on laboratory activities that require little or no money to implement. Field testers will receive a consulting fee of $450 plus $25 to implement the materials into their classrooms.

Astronomy Resources - Taking A Meteor Shower, Stephanie A. Althof

Iowa Science Teachers Journal

The summer months are often the most popular for skygazing. Mild weather combined with a host of appealing astronomical events tends to attract both amateur and professional astronomers to look skyward. One of the more brilliant and "flashy" events to observe is a meteor shower. As children, many of us remember watching a "falling" star shoot across the sky. Little did we know that what we were actually observing was a piece of space debris known as a' 'meteor.'' Meteors may appear at any time and from any direction, but most of the visible meteors viewed each year are parts …

Teaching Chemistry Safety: A Personal Issue, Judith Lemons

Iowa Science Teachers Journal

As chemistry teachers, it is our moral and legal duty to make the laboratory a safe and healthy place for our students. However, safety policies will be most effective if the students share the responsibilities for promoting safety and preventing accidents. We can help to motivate our students to remember and apply safety principles if we make safety a personal issue for each student. I have found that a student will more readily comply with laboratory rules on a regular basis if the rules are important for that student, and that student has actively participated in the safety learning process.

An Inexpensive Indicator For Acids And Baths, Susan Christensen, Yvonne Smith

Iowa Science Teachers Journal

Is your shampoo acidic, neutral or basic? Put more simply: what is the pH level of your shampoo? Have you ever wished to find the correct answer to that question? If so, you can repeat the experiment that we did to find the pH, not only of your shampoo, but of many other things as well.

This project was completed for GB 303, Field and Lab Biology for Elementary Teachers, at Emporia State University. While looking through a book on teaching science to elementary children (Schmidt and Rockcastle 1982), one of us developed the idea of using red cabbage juice …

The Pessimist And The Optimist, John D. White

Iowa Science Teachers Journal

Suppose that in 1945 a respected sage had been asked, "What do you see for the future?" and he had replied, "Rust, sand and soot." He would have been considered a pessimist. An optimistic sage might have replied instead: "The future will be powered entirely by atomic energy. Contagious disease will be eliminated by antibiotics such as penicillin. Harmful insects will be eradicated by DDT and similar chlorinated hydrocarbon insecticides."

Teaching The Logic Of Falsification: A Classroom Excercise, David Lopatto

Iowa Science Teachers Journal

Every science teacher soon discovers that the intuitions students use to solve problems are frequently at variance with the critical thinking skills required by science. 1be exercise presented here focuses on the value of making scientific hypotheses and then attempting to falsify rather than confirm them. When challenged to test a hypothesis, intuitive thinkers tend to show a confirmation bias, i.e., they will propose a test in which the results will be a positive instance of the hypothesis (Einhorn and Hogarth, 1978; Wason, 1960). Scientists, on the other hand, know that tests are specific instances that cannot inductively ''prove" the …

Reach-Ing For Our Dreams!, Sharon Kaufman, Tom Buckley

Iowa Science Teachers Journal

More than half a decade ago, several individuals and agency and organization representatives decided it was time to act upon the belief that conservation and the environment in Iowa needed a more generous and reliable funding source. Representatives of two dozen agencies and organizations, coordinated by the Iowa Natural Heritage Foundation, worked with several key legislators to draft the Resource Enhancement and Protection (REAP) program. The program itself passed the Iowa House and Senate unanimously and, after a little haggling over funding, was signed by Governor Branstad in May 1989.
