Chemistry Projects with Metals and Alloys

There are many interesting chemistry projects you can do using metals and alloys. Here are some of the best and most popular metal projects. Grow metal crystals, plate metals onto surfaces, identify them by their colors in a flame test and learn how to use them to perform the thermite reaction.

You can use chemistry to change the color of copper pennies to silver and gold.
You can use chemistry to change the color of copper pennies to silver and gold. Anne Helmenstine
Pennies ordinarily are copper-colored, but you can use chemistry know-how to turn them silver or even gold! No, you won't be transmuting the copper into precious metal, but you'll learn how alloys are made.

Bismuth is a crystalline white metal, with a pink tinge.
Bismuth is a crystalline white metal, with a pink tinge. The iridescent color of this bismuth crystal is the result of a thin oxide layer on its surface. Dschwen, wikipedia.org
You can grow bismuth crystals yourself. The crystals form rapidly from bismuth that you can melt over ordinary cooking heat.
