This article is really good because it explains how a simple demo used to determine the presence of carbon dioxide often used in biology class can be used for different disciplines such as physical science and earth science. As included in this article are extensions to the simple demo such as the effect of temperature on the production of carbon dioxide. This article can also be used by middle school teachers as well since the chemical needed is only a simple indicator. Reading the article also provides the background for a chemical reaction and is ideal in a chemistry classroom.
