This experiment features an investigative approach designed for the introductory science or engineering major and integrates concepts in the fields of chemistry, biology, and physics. Derived from faculty research interests, this novel experiment gives students the opportunity to draw conclusions from tests performed to illustrate the connection between molecular structure and macroscopic properties. The chemical synthesis of the compounds studied further enhances the connection between molecular structure and macroscopic physical properties. The results of two separate physical measurements, refractometry and absorption spectroscopy, are combined to calculate a microscopic, but very practical, property of chiral nematic liquidsthe pitch of the helix formed in the liquid crystalline phase.

Assessing the Effect of Web-Based Learning Tools on Student Understanding of Stoichiometry Using Knowledge Space Theory  Ramesh D. Arasasingham, Mare Taagepera, Frank Potter, Ingrid Martorell, and Stacy Lonjers
This paper reports a comparative study using knowledge space theory (KST) to assess the impact of a Web-based instructional software program on students' understanding of the concept of stoichiometry. The software program called Mastering Chemistry Web (MCWeb) allows students to practice problems that emphasize the development of molecular-level conceptualization and visualization, analytical reasoning, and proportional reasoning, as well as learning to recognize and relate different representations in chemistry. The experimental design compared students in two sections taught by the same instructor. One section used the MCWeb instructional software as homework (MCWeb group) while the other section used text-based homework (non-MCWeb group, control).

This paper discusses the results of a survey conducted to ascertain the causes of attrition among 819 students who had successfully completed a remedial chemistry course over the previous three years with a grade of A, B, or C, yet had not enrolled in the subsequent chemistry course at Texas Tech University. Approximately 22% of the recipients completed and returned the survey instrument. The distribution of responses was largely independent of the type of instructor (temporary or permanent faculty), the academic year the remedial course was taken, or the grade received.

In place of traditional cookbook laboratory exercises, a nonmajors' chemistry course uses a demonstration-focused laboratory to understand basic chemical theories. Each student spends the lab session preparing, practicing, and learning the chemistry of two unique demonstrations. By selecting demonstrations of different concepts, the students cover the same breadth and type of themes as a traditional laboratory in a new and exciting format. Twice during the semester, students from the course prepare and present two demonstration shows as an outreach program to 3rd5th graders at local elementary schools.

Kinetics of Alcohol Dehydrogenase-Catalyzed Oxidation of Ethanol Followed by Visible Spectroscopy  Kestutis Bendinskas, Christopher DiJiacomo, Allison Krill, and Ed Vitz
A two-week biochemistry experiment was introduced in the second-semester general chemistry laboratory to study the oxidation of ethanol in vitro in the presence of the enzyme alcohol dehydrogenase (ADH). This reaction should pique student interest because the same reaction also occurs in human bodies when alcoholic drinks are consumed. Procedures were developed to follow the biochemical reaction by visible spectroscopy and to avoid specialized equipment. The effect of substrate concentration on the rate of this enzymatic reaction was investigated during the first week. The effects of temperature, pH, the specificity of the enzyme to several substrates, and the enzyme's inhibition by heavy metals were explored during the second week.

Greenhouse gases feature in many courses in applied chemistry as well as in courses on environmental science, atmospheric chemistry, and so on. We hear a great deal about such matters from the media.

Recently in teaching about greenhouse gases to MSc students I have thought of a link between the topical and classical matters that is pedagogically interesting and might be of value to others teaching in this subject area.

On the Buoyancy of a Helium-Filled Balloon  John E. Harriman
It is shown by expansion of the exponential in the barometric formula that the forces due to pressure acting on a balloon are of the form (PV/RT)Mg and that results agree with those suggested by Archimedes principle. Einstein's equivalence principal provides an answer to what balloons will do in an accelerated car.

Departing from Lectures: An Evaluation of a Peer-Led Guided Inquiry Alternative  Scott E. Lewis and Jennifer E. Lewis
To improve a large-enrollment general chemistry course based on conventional lectures, we instituted a reform combining peer-led team learning with a guided inquiry approach, together called peer-led guided inquiry (PLGI). For one group of first-semester general chemistry students, a PLGI session was combined with two lectures per week, and this group was compared to a control group that had the usual three lectures per week. Students were compared based on performance on identical course exams and on a final exam from the ACS Examinations Institute given at the end of the semester. The experimental group was found to perform better than the control group overall, in spite of experiencing one fewer lecture each week.

Lipid Extraction and Cholesterol Quantification: A Simple Protocol  M. Carmo Barreto
A fast and simple protocol for lipid extraction from egg yolk and walnut is presented. Students learn to extract total lipids from both sources and to assess the quantity of cholesterol in lipid extracts by the LiebermannBuchard method, in a semi-quantitative way. This experiment is easily done in a two-hour lab period, except for the evaporation of lipid extracts to dryness, which proceeds overnight and is weighed by the students the following day

Measuring Viscoelastic Deformation with an Optical Mouse  T. W. Ng
A simple demonstration of viscoelasticity can be carried out by attaching a weight to a polymer film and watching it extend over time. For accurate and quantifiable data on the deformation, an electronic displacement sensor should be incorporated. Most of such sensors are expensive. Here, an optical mouse was demonstrated to provide accurate data at low cost. The experiment was also devised in a manner to allow students to learn about viscoelastic deformation experientially.

Using Organic Light-Emitting Electrochemical Thin-Film Devices To Teach Materials Science  Hannah Sevian, Sean Müller, Hartmut Rudmann, and Michael F. Rubner
Light-emitting thin films provide an excellent opportunity to learn about principles of electrochemistry, spectroscopy, microscopic structure of the solid state, basic circuits, and engineering design. There is currently strong interest in academic and industrial engineering research centering on developing organic light-emitting devices for applications in flat panel displays. In this educational module, designed for high school or introductory undergraduate courses, students learn how to make a ruthenium-based thin-film device. In the process, they learn about the solid-state electrochemistry at work in the film, as well as the electroluminescence that results when current passes through the device.

Introduction of Mass Spectrometry in a First-Semester General Chemistry Laboratory Course: Quantification of MTBE or DMSO in Water  Mike Solow
An experiment has been developed to introduce first-semester general chemistry students to mass spectrometry. Students analyze water samples contaminated with a known compound, either DMSO or MTBE. Students are asked to determine the concentration of the compound in the water. In performing this experiment, students should learn (i) how the mass of an atom or molecule is determined, (ii) the effect of the presence of different isotopes on molecular mass, (iii) the role of an internal standard, and (iv) how mass spectrometry is used in answering various scientific questions.
