Mathematics / Science Demonstration Classrooms In Iowa

Iowa Science Teachers Journal

Last fall, about 200 mathematics and science educators participated in the Governor's II Conference on Mathematics and Science Reform. The conference focused on achieving integration of math and science in Iowa by using model classrooms. Five months later, Iowa teachers, administrators and staff continue to develop model classrooms.

A New Perspective For Science Inservice: Problem Solving Demonstration Classrooms, Julie L. Wilson, Edward L. Pizzini

Iowa Science Teachers Journal

"Project: Problem Solving in the Model Classroom" was begun one year before the Governor's II Conference as a cooperative effort between the University of Iowa and a number of Iowa school districts. The Dwight D. Eisenhower funded program was intended to develop model classrooms that used problem solving with math/science, Science/Technology /Society (STS) or technology as effective classroom practice. The project has become an integration of inservice strategies, demonstration classrooms and reform initiatives that improve science education in Iowa. At the Governor's II Conference, we recognized that future model classrooms could benefit from our experience, specifically our rationale, development of …

Demonstration Classrooms: A Thematic Approach To Science/Mathematics Integration, Carl W. Bollwinkel, Barbara A. Bonnett, Rosalie J. Cochran

Iowa Science Teachers Journal

A fundamental principle of ecology is that "everything is interconnected." This observation holds true in the academic as well as the natural world; if we study an environmental issue in depth, we find that it cannot be resolved by means of any single discipline. Environmental studies transcend all disciplines so as to include the sciences, mathematics, technology, social studies, language arts and the practical and fine arts. The science component, ecology, is itself an integrating rather than a splintering science. It draws together the traditionally separate disciplines of biology, chemistry, physics and earth science. Mathematics provides a tool for quantifying …

Model Demonstration Elementary Classrooms In Northeast Iowa: The Luther College Project, Darrel Hoff, Joyce Becker, Nanette Eklund, Wendy Stevens

Iowa Science Teachers Journal

Luther College has a tradition of elementary teacher preparation stretching back to the tum of the century. It was therefore fitting that Luther College receive the only Eisenhower model demonstration program grant given to an Iowa four-year college. Built on outreaches and contacts developed by a teacher enhancement summer workshop held on the Luther Campus in 1993, the new program extends its outreach to the entire Northeast Iowa region.

Editor's Corner - Preserving Biodiversity: Notes To A Korean Grandson, Carl W. Bollwinkel

Iowa Science Teachers Journal

One of the things that makes this world such a wonderful place is the variety of living things. There are thousands and thousands kinds of plants and animals. Some are so tiny we cannot see them without a magnifying glass. Some are bigger than elephants. Some, like parrots, have bright colors. Some, like orchids, have very strange shapes. Some, like people, come in different sizes, shapes and colors and do very interesting things. There are many differences in all these living things and we call this "diversity."

Estimation Of Percent Body Fat By Hydrostatic Weighing In High Schools, Fred W. Kolkhorst

Iowa Science Teachers Journal

Concerns with fitness have increased interest in body composition and ideal body weight. Although anthropometric (e.g. skinfold) measurements can quickly determine general body composition, hydrostatic weighings are more accurate. While most exercise physiology laboratories on university campuses have a specialized tank for performing hydrostatic weighings, adequate stations can be set up in any swimming pool for a minimal initial cost. Several scientific concepts can be demonstrated during this exercise: measurement of lung volumes, determination of body density and calculation of percent body fat.

Science Notes - The Future Of Eisenhower Funds

Iowa Science Teachers Journal

Many local educators may be unaware that passage of the national "GOALS 2000" legislation will have a direct and perhaps dramatic effect on the Dwight D. Eisenhower Mathematics and Science Education Program (IKE), the Department of Education's largest program for professional development. GOALS 2000 will permit the Secretary of Education to waive the regulatory and statutory requirements of the original IKE legislation when a state files an application to implement its statewide planning for education reform.

The Pleistocene Glacial Record At Two Quarries In Decatur County, Iowa, Keith E. Schilling, Robert A. Stewart

Journal of the Iowa Academy of Science: JIAS

The Pleistocene stratigraphy and sedimentology of two quarry exposures near Grand River and Decatur City in Decatur County, Iowa document a sequence of Pleistocene sediments overlying striated Pennsylvanian limestone which represent at least two pre-Illinoian glacial advances into the ancestral Grand River valley. Two pre-Illinoian diarnictons separated by a clast pavement were observed at the Decatur City quarry; a single diarnicton was present at the Grand River quarry. At both quarries, the diarnictons exhibit comparable lithologic properties and are genetically interpreted as basal tills. The pre-Illinoian tills are tentatively correlated with the Alburnett Formation in eastern Iowa, primarily on the …

Competitive Abilities Of Oat And Barley Varieties, B. D. Mcbratney, K. J. Frey

Journal of the Iowa Academy of Science: JIAS

Competitive ability of a plant genotype reflects its capacity to yield well and compete successfully for light, moisture, and nutrients when grown with similar or dissimilar genotypes. This trait is important to plant breeding because most breeding populations are propagated in mixed or competitive stands. The objective of this study was to assess the competitive abilities of oat and barley genotypes.

Two sets of oat and barley genotypes were evaluated for competitive ability. Set I consisted of five oat varieties, and Set II consisted of two barley and three oat varieties. Neither set, when averaged, showed over- or under-compensation with …

The Early History And Recent Trends In Iowa Herpetology, Reeve M. Bailey, James L. Christiansen

Journal of the Iowa Academy of Science: JIAS

Herpetological exploration of Iowa began in 1823 with Long's expedition to the Rocky Mountains. From that time until an 1892 publication by Osborn based on Iowa specimens, herpetological research in the state was minor and incidental. Several significant reports appeared after that date involving analysis of Iowa specimens and from 1938 to 1944 a major base-line collection of the amphibians and reptiles of Iowa was established. Studies after that time have added a few species to Iowa’s known herpetofauna but recently have concentrated not only on composition of the fauna and distribution, but emphasized population changes, ecological relationships, and better …

Some Significant Iowa Plant Records From The Herbarium Of University Of Nebraska At Omaha, Barbara L. Wilson

Journal of the Iowa Academy of Science: JIAS

Though the herbarium of University of Nebraska at Omaha (OMA) lies outside the state boundaries, it contains a number of interesting western Iowa records. Publicizing these and other little-known Iowa plant records is especially important at this time, since a checklist of Iowa's vascular plants, compiled by Eilers and Roosa, is nearing completion.
