Kinetic Analysis of Amylase Using Quantitative Benedict's and Iodine Starch Reagents Beverly Cochran, Deborah Lunday, and Frank Miskevich
This laboratory emphasizes that enzymes mediate the conversion of a substrate into a product and that either the concentration of product or reactant may be used to follow the course of a reaction. It does so by using an inexpensive scanner and open-source image analysis software to quantify amylase activity through the breakdown of starch and the appearance of glucose.

Mineral Analysis of Whole Grain Total Cereal Paul Hooker
This article describes the quantitative analysis of the elements iron, zinc, and calcium in Whole Grain Total Cereal, a cereal product that claims to contain 100% of the daily value of several vitamins and minerals. This experiment can be implemented at several instructional levels including chemistry courses for science and nonscience majors, and in more advanced chemistry courses such as quantitative or instrumental analysis.
