View Resource Chemical Hand Warmer Experiment: Oxidation of a Metal

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity to illustrate the heat energy that is given off during the oxidation of iron. The class will analyze commercial hand warmers and the chemical reaction that allows them to heat up inside their plastic bags. The lesson includes information on the laboratory procedure. Discussion questions are also included.

View Resource Speed Rusting and Hot Hands

This experiment will demonstrate the heat that is released when iron is oxidized. Students will learn to prepare chemical mixtures safely, identify when a chemical reaction is taking place, observe the results of an exothermic chemical reaction and the effects of differing constituents on the rate of the reaction, and apply their observations to the refining and corrosion of iron. This...

View Resource Redox Activity

This resource provides an introductory activity on redox reactions. As the module states, "Redox is short for reduction/oxidation, a pair of chemical processes that always occur together. Reduction is a gain of electrons, and oxidation involves a loss of electrons." The activity covers concepts such as electronegativity and electron distribution, sharing electrons differently, full exchange of...

View Resource Redox Assessment

This brief assessment on Redox reactions is intended to be used after students have completed the introductory activity on the topic. The assessment consists of 10 multiple choice and short answer questions. Although a preview of the activity is available, instructors and students are encouraged to sign up with the Electron Technologies site before starting to use these materials.

View Resource Wet vs. Dry Oxidation Processes

In this YouTube video, created by Southwest Center for Microsystems Education (SCME), viewers can watch an animation on the the difference between wet and dry thermal oxidation processes. This animation "shows a side by side comparison of a wet oxidation process vs. a dry oxidation process. Both processes use an oxygen source to grow silicon dioxide (SiO2) on a silicon wafer heated furnace. Wet ...
