The Penny Experiment Revisited: An Illustration of Significant Figures, Accuracy, Precision, and Data Analysis  Joseph Bularzik
In this general chemistry laboratory the densities of pennies are measured by weighing them and using two different methods to measure their volumes. The average and standard deviation calculated for the resulting densities demonstrate that one measurement method is more accurate while the other is more precise.

Improving Conceptions in Analytical Chemistry: ci Vi = cf Vf  Margarita Rodríguez-López and Arnaldo Carrasquillo Jr.
A common misconception related to analytical chemistry, which may be generalized as the failure to recognize and to account analytically for changes in substance density, is discussed. A cautionary example is made through the use of mass-based units of composition during volumetric dilution. The correct application of the volumetric dilution equation ci Vi = cf Vf is discussed. A quantitative description of the systematic error introduced by incorrect use of the volumetric dilution equation is also specified.

Students were tested for their understanding of 25 words and five symbols commonly used in connection with chemical equilibrium. This test showed that most of the students had an inadequate grasp of the meaning of all five symbols. It also showed that, on the average, their understanding of symbols was more problematic than their understanding of words.

A Living Periodic Table  James L. Marshall
A complete "living" periodic table of samples of all the elements through uranium is described. In many instances a sample of an element is accompanied by a direct commercial application. This periodic table is very helpful in enabling the student to gain a hands-on understanding of the true nature of the elements--as opposed to the more usual compilation of mere abstract data.

A challenging self-contained qualitative analysis test for transition metal compounds comprising nine unknowns whereby the unknown solutions can be systematically identified, without relying on external reagents, by inter-mixing the unknown samples. The names of the samples are made known, but their correspondence with the samples is concealed. A representative range of transition metal compounds was selected, together with two complementary main-group compounds. This "9-bottle" test encourages logical deduction and analytical thinking.
