An Easy and Effective Classroom Demonstration of Population Distributions  Marjorie A. Jones
Using a simple experimental design and easily obtained materials, a classroom experiment was conducted to demonstrate normal-distribution behavior for a population. We used popcorn and a hot-air popper. Popped kernels were collected with time and data were plotted as popped kernels per time interval versus time. The data clearly showed a normal (Gaussian) distribution.

A mole of M&M's   Merlo, Carmela; Turner, Kathleen E.
Engaging students by asking the question: How thick would the layer of M&M candies be if we covered the continental United States with a mole of these candies? Compare this to a mole of water.

KC? Discoverer: Exploring the properties of the chemical elements  Liebel, Michael
This software program allows users to explore a large number of properties of the elements. The program can find all elements associated with a certain property, graph numeric properties against other numeric properties, list elements, sort elements, and use the periodic table to select elements.

The length of a pestle: A class exercise in measurement and statistical analysis  O'Reilly, James E.
Too many students get through chemistry without acquiring a basic understanding and appreciation of the concepts of measurement science. The purpose of this report is to outline an extremely simple class exercise as a concrete paradigm of the entire process of making chemical measurements and treating data.
