Setting Fires To Stem Cell Research, Roxanne Greitz Miller Jan 2005

Setting Fires To Stem Cell Research, Roxanne Greitz Miller

Education Faculty Articles and Research

The goal of this lesson is to present the basic scientific knowledge about stem cells, the promise of stem cell research to medicine, and the ethical considerations and arguments involved. One of the challenges of discussing stem cell research is that the field is constantly evolving and the most current information changes almost daily. Few science texts contain stem cell information, and those that do are generally written at a reading level above that of a typical middle grade student. In the lesson, students are introduced to the FIRES strategy and given an opportunity to evaluate stem cell information from …

Worldview, Science And The Understanding Of Nature, William W. Cobern Jan 2005

Worldview, Science And The Understanding Of Nature, William W. Cobern

Scientific Literacy and Cultural Studies Project

I am drawn to Nature because I see in Nature the handwork of God and I wonder what are our responsibilities as stewards of Nature? Being of a scientific bent, I wonder how Nature works? I wonder how Nature came to be? In other words, my thoughts– my everyday thoughts– about Nature are rooted in deep, fundamental beliefs that I hold about my life and the world in which I live, that is, my worldview. Nature of course is the traditional domain in which the “natural” sciences operate, but how we understand science and Nature is rooted in our worldview. …

Days Of Our Spineless Lives: A Never Ending Saga, Lori Ihrig

Iowa Science Teachers Journal

This activity is an interdisciplinary method for engaging students in biological investigations through working with living aquatic invertebrates. The learning cycle begins with students conducting fieldwork to collect aquatic invertebrates. Students then think and propose ideas to create an observation record that they can use to study their organisms in the classroom. Finally, through the use of well-phrased questions along with wait-time, positive nonverbal responses, and non-judgmental responses, the teacher is an ally working with students in inquiry to generate the requirements of a final project. This article promotes National Science Education Content Standards, A, C, and F, and Iowa …

The Moths Of Neal Smith National Wildlife Refuge: A Preliminary Assessment, Michelle N. Lewis, Renae M. Steichen, Keith S. Summerville Jan 2005

The Moths Of Neal Smith National Wildlife Refuge: A Preliminary Assessment, Michelle N. Lewis, Renae M. Steichen, Keith S. Summerville

Journal of the Iowa Academy of Science: JIAS

North American prairie systems are believed to have supported substantial insect biodiversity. Loss of prairie and oak savanna habitats, however, has been severe in many Midwestern states, including Iowa. An unanswered question facing land managers interested in restoring tallgrass prairies to the Iowan landscape is the degree to which restored habitats contain native insect species that are dependent upon prairie habitat. This study reports data from a preliminary survey of the moths of Neal Smith National Wildlife Refuge, a 2,292-ha prairie and oak savanna restoration site in central Iowa. We identified and cataloged a total of 426 species of moths …

Iowa's Sand Prairie State Preserves: Anomalous Grain-Size Distributions And Optically Stimulated Luminescence (Osl) Dates, Steven H. Emerman, Brian R. Depew, Lisa K. Anderson Jan 2005

Iowa's Sand Prairie State Preserves: Anomalous Grain-Size Distributions And Optically Stimulated Luminescence (Osl) Dates, Steven H. Emerman, Brian R. Depew, Lisa K. Anderson

Journal of the Iowa Academy of Science: JIAS

Grain-size distributions and optically stimulated luminescence (OSL) dates were obtained for the sand from Iowa's five sand prairie state preserves, which are Behren's Ponds and Woodland, Cedar Hills Sand Prairie, Kish-Ke-Kosh Prairie, Marietta Sand Prairie and Rock Island. OSL dates ranged from the late Pleistocene (15,560 years B.P.) to the very late Holocene (as recent as 590 years B.P.), indicating that the late Pleistocene and Holocene Epochs in Iowa have seen multiple episodes of aridity, which is consistent with results from the Nebraska Sand Hills and eolian sand stringers in southeastern Minnesota. The grain-size distributions were anomalous in that, compared …

Letter To The Editor - Conservation Of Freshwater Mussels In Iowa, K. Elizabeth Poole Jan 2005

Letter To The Editor - Conservation Of Freshwater Mussels In Iowa, K. Elizabeth Poole

Journal of the Iowa Academy of Science: JIAS

Freshwater mussels occur in a variety of aquatic ecosystems worldwide but nowhere is mussel species richness as high as is reported in North America. With nearly 300 recorded species in the U.S., mussels are key components of freshwater biodiversity playing a vital role in benthic communities. Ecologically important in biological processing and nutrient cycling, mussels are also an important food item for a variety of mammals including mink, otter, and raccoon. In addition to ecological importance, freshwater mussels have been economically important in the production of cultured pearls.

Hydrogeology Of Hanging Bog State Preserve: The Role Of Hillside Seeps In Draining The Iowan Surface, William L. Niemann Jan 2005

Hydrogeology Of Hanging Bog State Preserve: The Role Of Hillside Seeps In Draining The Iowan Surface, William L. Niemann

Journal of the Iowa Academy of Science: JIAS

Along the margin of the Cedar River Valley, groundwater discharges from eroded and weathered glacial materials of the Iowan Surface to modern alluvial deposits of the valley floor. Hanging Bog State Preserve, located along this topographic, geologic, and hydrologic boundary, represents one such groundwater discharge location, in the form of a perennial hillside seep. Based on detailed monitoring of surface water and groundwater levels within the preserve for a one-year period, it is shown that a significant quantity of groundwater, collected from a disproportionately large recharge area, is funneled to the valley wall at this site and subsequently carried to …

Aspects Of An Interior Stream Clam Midden From 1915 At Quasqueton, Buchanan County Iowa, Dennis W. Schlicht Jan 2005

Aspects Of An Interior Stream Clam Midden From 1915 At Quasqueton, Buchanan County Iowa, Dennis W. Schlicht

Journal of the Iowa Academy of Science: JIAS

During clam surveys on the Wapsipinicon River in 1991 buried clams were observed in a bank of the river at Quasqueton, Buchanan County, Iowa. An interview with the landowner revealed that the clams were from a 1915 local clamming operation. Excavation and examination of many of the clams reveal interesting differences in species composition and size, when compared to more recent specimens from the river. Observations on the midden were recorded, species determinations were made and measurements were taken. Comparisons are made to two other modern surface surveys on the river. Differences were observed in both species composition and shell …

Introducing Students To Polar And Non-Polar Interactions Through Inquiry, Jerrid Kruse Jan 2005

Introducing Students To Polar And Non-Polar Interactions Through Inquiry, Jerrid Kruse

Iowa Science Teachers Journal

Almost half of all chemistry teachers do not use inquiry in their classroom. Teachers cite classroom management, safety, and workload as reasons for not implementing inquiry techniques in their classroom (Deters, 2004). These teachers may resist laboratory-based inquiry finding it too daunting for themselves and their students. However, both students and teachers can progressively move to laboratory-based inquiry by first starting with less demanding science inquiry. This article describes an inquiry atmosphere created in a discussion classroom setting where students only minimally interact with materials. Students investigate macroscopic properties of water and hexane at their desks and the teacher performs …

The Unionid Mussels (Mollusca: Bivalvia: Unionidae) Of Missouri River Floodplain Ditches In Fremont County Southwestern Iowa And Atchison And Holt Counties Northwestern Missouri, Ellet Hoke

Journal of the Iowa Academy of Science: JIAS

A survey of ditches in the Missouri River floodplain in southwestern Iowa and northwestern Missouri resulted in the recovery of nine unionid mollusk species. The floodplain ditches may provide valuable habitat for mussels in a region that has suffered a tremendous decrease in productive aquatic habitats over the past sixty-eight years. Additional survey activity is needed to determine the complete inventory of unionid mollusks in the area.
