Purpose: 


The purpose of this science fair project is to determine which type of metal is the most rust resistant.  Rust can be red, brown, and yellow.  Rust can be scaly or powdery in consistency.  Rust can form due to water and salt.  Iron reacts with oxygen to form iron oxide which is rust.  Aluminum reacts with oxygen to form aluminum oxide, while copper produces copper carbonate.  This science fair project needs to be completed over at least ten days. 

 

Hypothesis: 


The different types of metals will produce more rust.  Metals exposed to saltwater will produce more rust faster than metals exposed to tap water.


Variables:


Type of metal (steel, copper, zinc, aluminum)

Type of water (saltwater, tap water)


Materials Needed:


  • 10 clear cups
  • 10 pencils
  • Salt
  • Measuring cup
  • Spoon
  • Tap water
  • Masking tape
  • Markers
  • 12 inches of steel wire cut into two equal pieces
  • 12 inches of copper wire cut into two equal pieces
  • 12 inches of zinc wire cut into two equal pieces
  • 12 inches of aluminum wire cut into two equal pieces
  • Camera (optional)
