The Occurrence Of Chestnut Lamprey (Lchthyomyzon Castaneus; Pisces: Petromyzontidae) In The Chariton River In South-Central Iowa, Mark K. Flammang, John R. Olson

Journal of the Iowa Academy of Science: JIAS

In the mid-1990s, Iowa Department of Natural Resources (IDNR) Fisheries Bureau biologists began receiving reports from anglers of a parasitic lamprey attached to fish taken immediately downstream from Rathbun Lake on the Chariton River in south-central Iowa; these reports have continued to present. In 2002, the IDNR received and identified a chestnut lamprey (Ichthyomyzon castaneus Girard) from an angler who removed the lamprey from a common carp (Cyprinus carpio Linnaeus) he captured. This record was the first for a lamprey from the Chariton River drainage in Iowa. Five additional specimens of chestnut lamprey have been collected and identified …

Mammal Capture Success Of Scent Stations And Remote Cameras In Prairie And Forest Habitat, Marc N. Mckinney, Aaron M. Haines

Journal of the Iowa Academy of Science: JIAS

Two common noninvasive (i.e., no stress to the animal) methods used to survey mammals include track stations (i.e., track captures of mammals) and remote camera-traps (i.e., photo-captures of mammals). Our objectives were to compare capture effectiveness of both track stations and remote cameras in both forested and prairie habitats. This project was conducted on 4 study sires (2 forested sires and 2 prairie sites) located in Fayette County, Iowa. Each study site had 6 trapping stations 2:: 100 m apart. We monitored traps for a total of 216 trap nights and we recorded a total of 368 captures composed of …

The Vascular Flora Of Boone County, Iowa (2005-2008), Jimmie D. Thompson

Journal of the Iowa Academy of Science: JIAS

A vascular plant survey of Boone County, Iowa was conducted from 2005 to 2008 during which 1016 taxa (of which 761, or 75%, are native to central Iowa) were encountered (vouchered and/or observed). A search of literature and the vouchers of Iowa State University's Ada Hayden Herbarium (ISC) revealed 82 additional taxa (of which 57, or 70%, are native to Iowa), unvouchered or unobserved during the current study, as having occurred in the county. This total of 1098 taxa (979 species, 57 varieties, 39 subspecies, 23 hybrids) places Boone County first in vascular plant richness among 18 published county inventories …

Meaningful Distributed Instruction— Conceptual Previews For Symbolic Procedures, Edward C. Rathmell

Faculty Work

Understanding a symbolic procedure means far more than “getting the right answer.” A mathematical symbolic procedure or written skill involves step-bystep thinking that leads from a computational problem to a solution. Memorizing this step-by-step procedure may enable a student to answer the problem, even answer it correctly. Yes, that is important, but understanding means much more.

Trends In Environmental Concern By Grade Level: A Study Of Elementary, Middle, And High School Students, Ryan David Lensing

Dissertations and Theses @ UNI

Environmental concern has been frequently measured since the 1970's, however, much of this research has focused on adults. Of the studies that look at students, the majority focus on high school with little attention given to middle or elementary grades. None of these studies have looked at elementary, middle, and high school students from the same population. This study uses the NEP Scale for Children in conjunction with free response questions to examine the trends in environmental concern from 120 Catholic elementary, middle school, and high school students from Des Moines, Iowa. The findings show no significant differences in levels …

Struggling Learners Of Mathematics: An Investigation Of Their Learning Through Reform-Based Instruction, Jennifer Pothast

Time.....Is On Our Side?, Jerrid Kruse

Iowa Science Teachers Journal

Several articles in this issue explicitly note that their approach to the activity about which they write takes extra time. They make clear there is an “easier way to do it”. Yet the authors also note how the goals they have for students are better promoted through their “slower” activity. Whenever I discuss education reform with fellow teachers, the number one constraint that consistently arises is “time”.

Simple Machines: Promoting Student Application And Reflection, Sarah Borzo

Iowa Science Teachers Journal

Simple machines are a common elementary grades science topic. This article describes how I frame my simple machines unit using a problem and have students reflect on their initial designs as we learn about each machine. The students then apply their learning by preparing proposals for how they might use simple machines to aid in the building of a pyramid. This article promotes National Science Education Standards A, B, and E and Iowa Teaching Standards 1, 2, 3, and 5.

Weaving The Web Of Inquiry: An Activity Introducing Students To Marine Food Webs, Jena Kline, Ryan Dickinson

Iowa Science Teachers Journal

This activity engages students in a biological investigation focusing on marine life. Students receive pictures of several marine organisms, make observations, and propose a possible food web which includes each of the organisms. Students also explain to the class their rationale behind the construction of their food web. This activity promotes increased familiarity with food webs, ecosystems, and energy flow. While this activity focuses on marine life, the activities and strategies could be used with most any ecosystem of interest. This activity promotes National Science Education Standards A, C, F and G, and Iowa Teaching Standards 2, 3, 4, and …

Kicking The Tires Of Natural Selection: The Carriage Still Runs After 150 Years

Iowa Science Teachers Journal

Science is both tentative and durable. This is its great strength: as we discover new evidence, or find new ways to interpret existing evidence, scientific ideas can be modified, offering us a more complete and reliable picture of the universe. Helping your students understand this aspect of science not only reduces their resistance to learning about evolution, but also encourages deeper understanding about how science works.

That’S Not My Style: Myths About Learning And Teaching, Jerrid Kruse

Iowa Science Teachers Journal

The notion of “Learning styles” seems to be very popular these days in education. The idea that we all learn differently is intuitively appealing with the varied personalities, successes, and struggles of our students. However, the notion that each person learns differently is likely a myth (Olson, 2006; Feldon, 2005; Willingham, 2005). Students don't possess different learning styles; rather every student has unique prior knowledge, experiences, and developmental levels.

Gully And Stream Bank Erosion In Three Pastures With Different Management In Southeast Iowa, George N. Zaimes, Richard C. Schultz, Mustafa Tufekcioglu

Journal of the Iowa Academy of Science: JIAS

Gully and stream banks can be major sources of sediment and nutrients to surface waters, both major water quality problems in the United States. Sediment may also carry phosphorus to surface waters, the primary limiting nutrient causing eutrophication. Overgrazing can induce gully and stream bank erosion by reducing vegetation cover that weakens bank soil resistance to stream water flow. This study examines stream and gully bank erosion adjacent to continuous (CP), rotational (RP) and intensive rotational (IP) pastures, grazed by beef cattle in southeast Iowa. Stream and gully bank erosion were measured by: a) surveying the extent of the severely …

Earthwatch Expedition: Taking Research Experiences To The Classroom, Katherine J. Megivern

Iowa Science Teachers Journal

I participated in the Live from the Field Earthwatch Expedition - Mammals of Nova Scotia, through a fellowship awarded by Wells Fargo. During this experience I participated in research to study the abundance of mammals in Nova Scotia and determine the effect of climate change on natural systems. After this experience I developed an inquiry project for my students in which they study the populations of insects. The students develop their own questions, collect data and make sense of their research. By investigating populations, students are encouraged to see the wonderful biodiversity right in their backyard! This article Promotes National …
