An advanced undergraduate chemistry laboratory experiment to study the advantages and hazards of the coupling of NIR spectroscopy and chemometrics is described. The combination is commonly used for analysis and process control of various ingredients used in agriculture, petroleum and food products.

The Vitamin C Clock Reaction has now been adapted to serve as a student laboratory experiment in the education process of high-school and college-level general chemistry. Despite of imparting valuable knowledge, it also may be hazardous, as the tincture of iodine contains inflammable substances that may cause burning on prolonged exposure.

Research collaborations between chemists and other scientists resulted in significant outcomes such as development of software. Such collaboration provided a realistic learning experience for computer science students.

This article provides support to college science instructors who wish to implement new strategies to probe student understanding, not to prescribe a single best way to conduct a college science course.

Random-climb models enable undergraduate chemistry students to visualize polymer molecules, quantify their configurational properties, and relate molecular structure to a variety of physical properties. The model could serve as an introduction to more elaborate models of polymer molecules and could help in learning topics such as lattice models of…

The nanotechnology degree programs initiated at various institutions provided an excellent way of learning to look at the amazing opportunities that arise when various disciplines of science interact. The enrolled students were actively engaged in the subject matter and also expressed greater confidence in their ability to consider technology with…

An experiment is designed where students will be using both gold and silver nanoparticles to study the enhancement factors of organic molecules adsorbed to the surface of the nanoparticles during or after synthesis by using surface-enhanced Raman spectroscopy (SERS). The experiment has helped students learn about the theory and experimental…

Experiments suited for the undergraduate instructional laboratory in which the heats of formation of several aliphatic and aromatic compounds are calculated, are described. The experiments could be used to introduce students to commercially available computational chemistry and its thermodynamics, while assess and compare the energy content of…

The Biology department at Spelman, a historically black women's college has undertaken a major curriculum revision in the last few years. A primary goal of this revision is to increase the breadth of topics in biology classes. Historically, classes in the areas of ecology and evolution have been underrepresented whereas Spelman has always offered…

Inquiry-driven lab exercises require students to think carefully about a question, carry out an investigation of that question, and critically analyze the results of their investigation. Here, we describe the implementation and assessment of an inquiry-based laboratory exercise in which students obtain and analyze novel data that contribute to our…

Illustrates that the knowledge of crystal structure, particularly face centered cubic array, can be applied to an explanation of how a solid fuel nuclear reactor works. (MLH)

Describes Fraunhofer's scientific career as a glass and lens maker, a discoverer of dark lines in the solar spectrum, a corrector of lens aberration, and investigator of diffraction. Gives biographical data and anecdotes. Includes a bibliography, mainly of German sources. (GH)

Describes a technique that can be used to develop accuracy, precision, and a neat laboratory approach in the student. The technique can also be used to demonstrate the stoichiometry of a reaction. (GS)

The leap of a grasshopper is used as an introduction to the capabilities of muscle, using Newton's laws of motion and other standard equations as the basis of the study. (Author/PEB)

Describes the year of 1973 as a banner year for environmental geology and briefly details the areas where environmental applications originating from earth scientists are occurring. (BR)
