The Concentration Of Heavy Metals In Lincoln Nebraska's Tap Water, Evan Neuhaus
The Concentration Of Heavy Metals In Lincoln Nebraska's Tap Water, Evan Neuhaus
Honors Theses
Heavy metals are commonplace in nature, and are typically found in scarce quantities in all drinking sources. However, in high enough concentrations, they can have a myriad of negative health effects. This study seeks to find the concentrations of such metals in the Lincoln water supply utilizing the resources of the Water Center at the University of Nebraska at Lincoln. To test for discrete concentrations of trace elements, a method of using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was implemented. ICP-MS uses plasma to ionize and atomize a sample which is then filtered into a series of cones into a …

Periodic Table Club, Makayla Gill, Kailynn Jensen
Honors Expanded Learning Clubs
This club is dedicated to teaching the generation of future scientists the periodic table. This is designed to be a unique take on a STEM club that uses the periodic table as a backbone for a solid foundation in chemistry.
Isotopes In The Estuary: Conception And Application Of Stable And Radioactive Carbon, Derek Detweiler
Isotopes In The Estuary: Conception And Application Of Stable And Radioactive Carbon, Derek Detweiler
Reports
Grades: 9-12 Subjects: Chemistry | Environmental Science | Oceanography
In this interactive estuary-focused activity, students will examine stable and radioactive isotope data which provide information about the source and age of environmental samples such as plant and soil matter. Students will calculate average isotope ratios from five reference land types (forest, wetland, agriculture, industry, aquatic) and an unknown site within an estuary. Students will graph their calculated ratios and determine the land type that most impacts their estuary based on reference-to-unknown comparisons.

Using Interviews In Cer Projects: Options, Considerations, And Limitations, Deboarh G. Herrington, Patrick L. Daubenmire
Using Interviews In Cer Projects: Options, Considerations, And Limitations, Deboarh G. Herrington, Patrick L. Daubenmire
Peer Reviewed Articles
Interviews can be a powerful chemistry education research tool. Different from an assessment score or Likert-scale survey number, interviews can provide the researcher with a way to examine and describe what we cannot see, aspects such as feelings, thoughts, or explanations of thinking or behavior. Most people have no doubt seen countless interviews on TV news and talk shows. These sessions might convey interviewing as a spontaneous, easy, and straightforward process. However, using interviews as a meaningful research tool requires considerable thought, preparation, and practice. This chapter provides a general introduction to the use of interviews as a tool within …
Case Study Of A Successful Educational Partnership: University Of Illinois At Urbana-Champaign And The Illinois Mathematics And Science Academy, Dave Devol
Faculty Publications & Research
This article describes partnerships between an NCSSSMST member institution and a research university and the use of student-generated survey data as a means of both professional self-reflection and asking further questions. As a chemist, I have been trained to write in the style of scientists, and in fact I teach a course at the Illinois Mathematics and Science Academy on the methods of science and scientific writing. This article is intentionally not written in a scientific style; rather is written to convey a story of how a partnership between institutions naturally progressed into my current area of research into motivational …

Chem 109: General Chemistry I—A Peer Review Of Teaching Project Benchmark Portfolio, Eric D. Dodds
Chem 109: General Chemistry I—A Peer Review Of Teaching Project Benchmark Portfolio, Eric D. Dodds
UNL Faculty Course Portfolios
This portfolio has been developed for CHEM 109: General Chemistry I. The course is the first of a freshman level two semester sequence in General Chemistry taken by students with majors in a wide variety of technical and scientific disciplines. CHEM 109 is a high enrollment class, with class sizes for individual sections nearing 200 students. The development of this portfolio was conducted with the following objectives: 1. Clearly identify, justify, and codify the major learning objectives for this course, 2. Describe and rationalize the course structure and learning assessment methods, 3. Analyze and reflect on student achievement in the …
The Complexity Of Reform Efforts In Science Curriculum And Instruction: A Case Study Of The Illinois Mathematics And Science Academy Chemistry Teacher, Tang Wee Teo
IMSA History
This study explores how teacher-initiated site-based reform in a specialized STEM school is conceptualized and enacted, how and why curriculum reform ideas change in the process of enactment, what qualities of teacher agency are entailed, how these qualities are acquired, interplayed, become generative, and/or are influenced to effect different curriculum reform outcomes, and how different conditions support and further teacher agency to make a more defensible curriculum.
In a critical case study of a highly experienced and qualified science teacher, I follow a teacher who initiated efforts to reform the advanced chemistry curriculum. This teacher wanted to make the curriculum …
Chemistry In Second Life, Andrew Lang, Jean-Claude Bradley
Chemistry In Second Life, Andrew Lang, Jean-Claude Bradley
College of Science and Engineering Faculty Research and Scholarship
This review will focus on the current level on chemistry research, education, and visualization possible within the multi-user virtual environment of Second Life. We discuss how Second Life has been used as a platform for the interactive and collaborative visualization of data from molecules and proteins to spectra and experimental data. We then review how these visualizations can be scripted for immersive educational activities and real-life collaborative research. We also discuss the benefits of the social networking affordances of Second Life for both chemists and chemistry students.

The Spectral Game: Leveraging Open Data And Crowdsourcing For Education, Andrew Lang, Jean-Claude Bradley, Robert J. Lancashire, Anthony J. Williams
College of Science and Engineering Faculty Research and Scholarship
We report on the implementation of the Spectral Game, a web-based game where players try to match molecules to various forms of interactive spectra including 1D/2D NMR, Mass Spectrometry and Infrared spectra. Each correct selection earns the player one point and play continues until the player supplies an incorrect answer. The game is usually played using a web browser interface, although a version has been developed in the virtual 3D environment of Second Life. Spectra uploaded as Open Data to ChemSpider in JCAMP-DX format are used for the problem sets together with structures extracted from the website. The spectra are …
Visualizing Atomic Orbitals Using Second Life, Andrew Lang, David C. Kobilnyk
Visualizing Atomic Orbitals Using Second Life, Andrew Lang, David C. Kobilnyk
College of Science and Engineering Faculty Research and Scholarship
We demonstrate the usefulness of Second Life as a platform for enlivening major concepts in chemistry education. These concepts include absorption spectra, selection rules, quantum numbers, and atomic orbital shapes. We have built several exhibits in Second Life which provide 3-dimensional interactivity for each of those areas: an interactive experiment showing the absorption spectrum of hydrogen, an interactive model of selection rules showing allowed and forbidden transitions for each state, a 3-dimensional grid of orbitals showing the constraints on the values of quantum numbers, and a large-scale interactive orbital display allowing the user to choose and rotate to-scale atomic orbitals …
