Resolving Spectral Lines with a Periscope-Type DVD Spectroscope Fumitaka Wakabayashi
Describes the periscope-type of DVD spectroscope and demonstrates the numerical analysis of its emission and absorption spectra. This improved design allows one to observe and photograph visible spectra more easily and clearly than earlier models; it thus has the potential to be a cost-effective, powerful, and versatile tool for science education.

Simultaneous Display of Spectral Images and Graphs Using a Web Camera and Fiber-Optic Spectrophotometer Brian K. Niece
A method is presented for displaying images and graphs of spectra on a single screen in the classroom. The simultaneous display of both forms of the spectra helps students to make connections between the qualitative, visual spectra and quantitative, graphical representations.

Periodic Tables of Elemental Abundance Steven I. Dutch
Patterns of element abundance in the sun, chondrite meteorites, and the continental crust of the earth and the moon are portrayed on a periodic table. The abundance of each element is represented by a circle whose radius is proportional to the logarithm of the element's abundance.

Before There Was Chemistry: The Origin of the Elements as an Introduction to Chemistry Neil Glickstein
The use of cosmology as an interdisciplinary introduction to a chemistry course is discussed. Students read a variety of nontext sources in order to piece together the events of the early universe that led to the creation of the elements. An introduction to gravity, mass, time, distance, temperature, and density are all possible with thematic cohesion.

Screening and Sequential Experimentation: Simulations and Flame Atomic Absorption Spectrometry Experiments Richard J. Stolzberg
Students are introduced to screening and sequential experimentation using simulations and experimentation. The work begins with spreadsheet simulations and practice with the experimental design software. Students learn how to use the graphical output, normal quantile plots, to recognize the specific factors that affect the result of an experiment. In the laboratory, students make a preliminary investigation of the effect of six variables (flame observation height, flame stoichiometry, acetic acid, lamp current, wavelength, and slit width) on the atomic absorption signal for silver.

The use of an air-natural gas flame in atomic absorption Melucci, Robert C.
The experiment reported in this paper demonstrates that students can get excellent results using air-natural gas flame in atomic absorption, and a tremendous advantage in safety is gained for a small sacrifice in the limit of detectability.
