Gold Alloys
None of the gold used in jewelry is pure gold. Some gold isn't even 'gold'-colored (e.g., white gold). The different colors are due to the presence of other metals alloyed with the gold. This table gives common compositions of the different colors of gold.

Gold and Silver Pennies
Take copper-colored pennies and turn then silver, then make them gold. This is an easy chemistry project that uses common laboratory chemicals.

Hollow Penny Project
This is an easy chemistry project that uses common materials. You take a post-1982 penny, score the copper surface to expose the zinc interior, react the zinc with acid, and are left with a hollow copper penny.
