The thermite reaction is one your students will never forget. Flames, sparks, temperatures exceeding 2200 ºC and melted iron are all produced by this spectacular reaction. Thermite is a generic name given to a very high temperature reaction between a metal oxide and aluminum. The most common use of thermite is for fusion welding.
The thermite demonstration has always been one you wish you could do, but don’t because of the dangers in getting the reaction started. Recognizing this problem, Flinn Scientific has developed a special starting material called Thermite Igniting Sticks. These new igniting sticks are the most effective, safe and controllable way to start a thermite reaction. Simply light the igniting stick with a match, place it into a pile of thermite, and watch the reaction take place. It’s just that easy and safe. Teacher Demonstration Notes included.
Concepts: Exothermic reactions, oxidation–reduction, thermite reaction.
Time Required: 20 minutes
Note: Please remember that any demonstration where the reaction exceeds temperatures of 2200 ºC should always be done behind a safety shield and conducted in a fume hood or better yet outside. If you want to demonstrate a thermite reaction, this Flinn kit is your best choice.

Systems and system models
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
