A Modified Demonstration of the Catalytic Decomposition of Hydrogen Peroxide  Carlos Alexander Trujillo
A safer and cheaper version of the popular catalyzed decomposition of hydrogen peroxide demonstration commonly called the Elephants Toothpaste is presented. Hydrogen peroxide is decomposed in the presence of a surfactant by the enzyme catalase producing foam. Catalase has a higher activity compared with the traditional iodide and permits the use of diluted hydrogen peroxide solutions. The demonstration can be made with household products with similar amazing effects.

Small-Scale Kinetic Study of the Catalyzed Decomposition of Hydrogen Peroxide  Ronald O. Ragsdale, Jan C. Vanderhooft , and Arden P. Zipp
The decomposition of hydrogen peroxide can be studied directly and quickly by determining the rate of formation of oxygen bubbles produced. This experiment, like the iodine clock reaction, provides quantitative measurements for a general chemistry course.

A Kinetics Experiment To Demonstrate the Role of a Catalyst in a Chemical Reaction: A Versatile Exercise for General or Physical Chemistry Students  Christine L. Copper and Edward Koubek
By modifying the iodine clock reaction, students can use the initial rate method to observe the role of a catalyst in a chemical reaction via activation energy calculations and evaluate a proposed mechanism. They can also determine the order with respect to each reactant and the rate constants of the noncatalyzed and catalyzed reactions.
