Summer Undergraduate Research Program (SURP) Symposium
The Science Writing Heuristic (SWH) and Argument Driven Inquiry (ADI) are evidence-based laboratory approaches that emphasize the process of scientific argumentation (Burke et al., 2006; Rudd et al., 2001; Walker et al., 2011). The University of Northern Iowa utilized the SWH approach for over 10 years until research indicated that the cognitive load associated with the pre-lab, specifically, hindered students’ ability to participate in authentic scientific inquiry for the rest of the laboratory experiment (Bonde & Del Carlo, 2018). In response to this, a hybrid model of instruction integrating elements of both the SWH and ADI laboratory approaches was created …

Perturbations Observed In The Orbital Elements Of The Spectroscopic Binary 57 Cygni, Kenneth W. Mclaughlin, Janak Panthi
Perturbations Observed In The Orbital Elements Of The Spectroscopic Binary 57 Cygni, Kenneth W. Mclaughlin, Janak Panthi
Journal of the Iowa Academy of Science: JIAS
We present spectroscopy that confirms periodic Doppler-shifts along with photometry that reinforces a lack of eclipsing in the double-lined spectroscopic binary 57 Cygni. Our spectroscopy concentrates on a range encompassing H-alpha and the helium 667.8 nm line, where we find Doppler-shifts of both stars resolved in the helium line but less so in the broader H-alpha profile. Although we find the radial velocities derived from both lines reasonably consistent, we retained only the helium-line derived velocities for sinusoidal curve-fits to the orbital dependence. The fit-amplitudes specify the ratio of the stellar masses as 1.03 ± 0.05, in agreement with previous …
A Qualitative Comparison Of General Chemistry And Advanced Placement Chemistry Students’ Misconceptions Regarding Solution Chemistry, Megan Vandersee
A Qualitative Comparison Of General Chemistry And Advanced Placement Chemistry Students’ Misconceptions Regarding Solution Chemistry, Megan Vandersee
Annual Graduate Student Symposium
There has been much research on student misconceptions regarding the particulate nature of matter and its relation to solution chemistry (e.g. Adadan & Savasci, 2012; Calik & Ayas, 2005; Calik, Ayas, & Coll, 2009; Pinarbasi & Canpolat, 2003; K. J. Smith & Metz, 1996). However, there is a lack of information regarding student misconceptions in areas of solution chemistry such as factors affecting solubility, polarity & molecular interactions and colligative properties. This research compared the misconceptions in solution chemistry held by students who are approaching the end of an Advanced Placement (AP) chemistry course in the high school setting with …
Herbaceous Vascular Flora Of Forested Seep Wetlands In Winneshiek County, Iowa, Usa, Elizabeth A. Lynch, Anna Burke Weckwerth
Herbaceous Vascular Flora Of Forested Seep Wetlands In Winneshiek County, Iowa, Usa, Elizabeth A. Lynch, Anna Burke Weckwerth
Journal of the Iowa Academy of Science: JIAS
Forested seep wetlands dominated by skunk cabbage (Symplocarpus foetidus) occur frequently in the Canoe Creek watershed of the Upper Iowa River, but this type of wetland has not been described systematically in the upper Midwest. The goal of this study is to document the herbaceous plant flora of five seeps. Although individual seeps are small (200-500 m2), they provide habitat for a high number of plant species. Five seeps with total area less than 0.2 ha supported more than 120 native vascular herbaceous taxa, 20 of which have a coefficient of conservatism (C-value) of 7 or …
A Statistical, Spatial, And Hydrologic Comparison Of Gauge-Based And Mpe-Based Rainfall Measurements, Richard Bernatz
A Statistical, Spatial, And Hydrologic Comparison Of Gauge-Based And Mpe-Based Rainfall Measurements, Richard Bernatz
Journal of the Iowa Academy of Science: JIAS
Gauge-based and multi-sensor precipitation estimation (MPE) data are compared on hourly, daily, monthly and event time scales at site locations over a 12-year period. Gauge data is collected at 16 sites within a 950 km2 portion of the Upper Iowa River in northeast Iowa. Average relative MPE bias is positive for all but the event time scale, and has a magnitude of less than 0.10 for all scales. Gauge and MPE average correlation coefficients range from 0.73 on the hourly scale to 0.92 on the event and monthly scales. The MPE relative bias standard deviation decreases from 1.70 mm on …

Population Genetic Structure Of Asclepias Tuberosa In Northwest Iowa: A Comparison Within And Between Remnant Prairies And Commercially Available Seed, Jeffrey T. Ploegstra, Brittany De Ruyter, Tony Jelsma
Population Genetic Structure Of Asclepias Tuberosa In Northwest Iowa: A Comparison Within And Between Remnant Prairies And Commercially Available Seed, Jeffrey T. Ploegstra, Brittany De Ruyter, Tony Jelsma
Journal of the Iowa Academy of Science: JIAS
Isolated in scattered remnants, less than 0.1% of Iowa’s original tallgrass prairie remains. The small populations remaining are at risk for reduced genetic diversity, inbreeding depression, and outbreeding depression. In light of these concerns, we used microsatellite analysis to assess the genetic structure of butterfly milkweed (Asclepias tuberosa) populations on prairie remnants in northwest Iowa. We compared remnant populations with a restoration population at Dordt College in Sioux Center, Iowa, and with an Oklahoma seed source. Microsatellites identified for use in common milkweed (Asclepias syriaca) had sufficient polymorphism information content (PIC) across the butterfly milkweed ( …

Synchronous Rotation In The Eclipsing Binary 68 Herculis Inferred From Doppler Shifts In Its Spectrum And Light Curve Modeling, Kenneth W. Mclaughlin, Janak Panthi
Synchronous Rotation In The Eclipsing Binary 68 Herculis Inferred From Doppler Shifts In Its Spectrum And Light Curve Modeling, Kenneth W. Mclaughlin, Janak Panthi
Journal of the Iowa Academy of Science: JIAS
Our differential photometry of the eclipsing binary 68 Herculis through V- and R-filters shows periodic minima consistent with a previously established period. As a function of its orbital motion, we report spectra over a limited wavelength range encompassing H-alpha 656.3 nm and helium 667.8 nm lines. Doppler shifts of both stars were resolved in H-alpha, while only the more massive star rendered the helium line with Doppler shifts that agree with the radial velocity we derive for it from the H-alpha profile. Sinusoidal curve-fits to the orbital dependence of the radial velocities imply circular orbits for both components, with amplitudes …
Gene Expression Of Components Of The Insulin/Insulin-Like Signaling Pathway In Response To Heat Stress In The Garter Snake, Thamnophis Elegans, Tonia S. Schwartz, Anne M. Bronikowski
Gene Expression Of Components Of The Insulin/Insulin-Like Signaling Pathway In Response To Heat Stress In The Garter Snake, Thamnophis Elegans, Tonia S. Schwartz, Anne M. Bronikowski
Journal of the Iowa Academy of Science: JIAS
The insulin/insulin-like signaling (IIS) pathway is an evolutionary conserved molecular signaling pathway that regulates growth, reproduction, stress resistance, and longevity in response to nutrition and external stress. While the constituents of this pathway and their functions are relatively well understood in laboratory model animals, they have not been explored in many other organisms, with notable exceptions in the fisheries literature. We tested for the gene expression of four key components of this pathway in the garter snake (Thamnophis elegans) liver, and determine how the transcription of these components responds to heat stress. We found that the two insulin-like …

Improved Functional Prediction Of Hypothetical Proteins From Listeria Monocytogenes 08-5578, Michael J. Lagier, Brittany Bowman, Kelsey Brend, Katherine Hobbs, Michael Foggia, Mark Mcdaniel
Journal of the Iowa Academy of Science: JIAS
Listeria monocytogenes is a foodborne human pathogen responsible for listerosis. The genomes of several L. monocytogenes strains have been recently sequenced. The genome of L. monocytogenes 08-5578, which was in part responsible for a significant listerosis outbreak in 2008, contains an unexpectedly high percentage of protein-encoding genes (1,927 out of 3,161; 60.96%) autonomously annotated as hypothetical proteins. The aim of this study was to test whether a manual annotation strategy could be used to assign more meaningful functional names to the hypothetical proteins of 08-5578. A holistic, manual gene annotation strategy that utilized sequence homology, cellular localization predictions, structure-based evidence, …

The Role Of An Urban Tallgrass Prairie Remnant In Conservation: A Case Study In Central Iowa (Usa), Jimmie D. Thompson, Deborah Q. Lewis, William R. Norris
Journal of the Iowa Academy of Science: JIAS
Although more than 85% of Iowa (USA) was covered by tallgrass prairie at the time of settlement by Europeans in the early 19th century, less than 0.1% remains. The Richard W. Pohl State Preserve at Ames (IA) High School, surrounded on three sides by structures, roads, and other development, protects 4 ha of tallgrass prairie. The preserve, commonly referred to as Ames High Prairie (AHP), was grazed but never plowed under private ownership until its acquisition by the Ames School District in 1959.
Although considered for development as a parking lot or football field in the 1960s, the residents of …

Culturally Relevant Pedagogy: Secondary Mathematics In An Urban Classroom, Julia Glissmann North
Culturally Relevant Pedagogy: Secondary Mathematics In An Urban Classroom, Julia Glissmann North
Honors Program Theses
Research and test scores have shown that African-American, Latino, Native American, and other minority students are underachieving in secondary mathematics. This is concerning not only to school personnel – who are under pressure to have students perform well on standardized tests – but also to the future of the country. When teachers adopt a culturally relevant pedagogy, diverse students will have a better opportunity to learn and retain mathematical content. When academic content is taught in a culturally relevant way, students are able to retain the information, improve their performance in school, and become more informed participants in society. Through …

The Vascular Flora Of Clay Prairie State Preserve (Butler County, Iowa): Recommendations To The Iowa State Preserve System, Edwin L. Freese, William R. Norris
Journal of the Iowa Academy of Science: JIAS
Clay Prairie State Preserve (1.2 ha) is an upland prairie located in Butler County, IA, and represents one of the last remnants of black-soil tallgrass prairie in northeast Iowa. An annotated checklist of the vascular flora of Clay Prairie is presented here, based on a previously published flora of the preserve and recent field work conducted by the authors between 1997 to 2001, and 2008 to 2011. The preserve contains a diverse vascular flora representing 50 families, 145 genera and 214 taxa (174 native to Iowa). In comparison with 26 larger prairies (4 to 121 ha) protected in the Iowa …
