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.

Science Notes - Relationships In Physical Science Text Book Available

Iowa Science Teachers Journal

Project RAMPS (Relationships and Mathematics in Physical Science) has developed Relationships in Physical Science, a textbook based on the idea that mathematics and laboratory activities should be an integral part of science education. The mathematical exercises included in the text are intended to help students gain a better understanding of the scientific concepts they are studying. Most of the materials necessary for the activities are already in the classroom or can be obtained from a supermarket.

Checklist Of The Vascular Flora Of Page County, Iowa, Barbara L. Wilson

Journal of the Iowa Academy of Science: JIAS

The vascular flora of Page County, Iowa, was studied from 1987 through 1991. Seven hundred forty two species and four hybrids of vascular plants were found. A quarter of the flora consists of non-native species. Taxa not previously reported in Iowa include: Amsinckia intermedia, Brassica kaber, Cardaria chalapensis, Callirhoe bushii, Carex mesochorea, Eleocharis xyridiformis, Euphorbia prostrata, Lactuca saligna, Leontodon autumnalis, Scirpus mucronatus, Sclerochloa dura, and Vernonia arkansana.

Necklace Radio Transmitter Attachment For Pheasants, Terry Z. Riley, Bruce A. Fistler

Journal of the Iowa Academy of Science: JIAS

We tested a pre-assembled, necklace-radio-transmitter-attachment design on female ring-necked pheasants (Phasianus colchicus) in northern Iowa. Birds were captured by nightlighting and bait trapping between September 1989 and March 1990. Radio transmitters were attached to 128 using a wire necklace. Two birds had problems adapting to the necklace, and 3 birds removed them. Twenty-three birds were still alive and wearing necklaces at the end of the study, for an average of 318 (SD= ± 52) days. Ease of attachment, long durability, light weight, and minimal bulk make the necklace an effective alternative to harness and poncho mounts.

Book Review: Landforms Of Iowa, Michael L. Thompson

Journal of the Iowa Academy of Science: JIAS

Many of us are interested in the landscape around us. We ask: Why is this hill so steep or why is that valley so wide? Why does my garden's soil have so much clay? Why does Iowa have no mountains' Landforms of Iowa should capture a broad audience of teachers, students, agriculturalists of all sorts, historians, homemakers, naturalists, botanists, biologists, foresters, geographers, civil engineers, as well as geologists and pedologists-in short, just about any Iowan who has ever wondered how and when the landscape at his or her doorstep or outside the car window was fashioned. Its stated purposes are …

Fifty Years Of Fisheries Management M An Obstinate Prairie Lake, Dennis L. Scarnecchia, James R. Wahl

Journal of the Iowa Academy of Science: JIAS

Little Wall Lake, a shallow 104 ha glacial lake in Hamilton County, Iowa, has been manipulated for about 50 years by fishery managers in an attempt to provide a stable sport fishery. Managers have used dredging, water level manipulation, aquatic vegetation control, mechanical fish removal and fish eradication with toxicants, sport fish stocking, introduction of piscivorous fish, artificial habitat structures, and winter aeration. Attempts to stabilize the fishery have been unsuccessful, and because of overpopulation and stunting of panfishes, total fish eradications were conducted in 1977 and 1989. We review the history of management efforts on the lake, and suggest …
