As with all Event-Based Science modules, much of the information that students need is provided in the pages of Fraud!. However, more information is needed. Information about art and chemistry will add to the authenticity of your study.
Below are some World-Wide Web sites where additional information is available. Click on the highlighted words and be linked with helpful sites.

In Part 1 of the Science Activity called Rusty Elements, students are asked to burn steel wool and describe changes that occur. They then place some steel wool in a humid environment and describe changes that occur. The teacher's guide indicates that rust is formed in both cases. This is not exactly true.
Burning is a reaction between iron and oxygen that produces iron oxide. Since this iron oxide is black and not the red color of rust, it must be Iron(II) oxide (or ferrous oxide, FeO) which is a black powder. Iron (III) oxide (or ferric oxide Fe2O3) is red and is produced when iron rusts.
The purpose of Part I of the activity is to demonstrate that an iron compound is formed by the reaction between iron and oxygen. Also, that the compound is different from the element iron.
Both of these things are true, whether or not the compound is formed by burning or rusting.
Thanks to Joe Muskin for noting this discrepancy.
