Many metals oxidize and corrode, but rust, or iron oxide, is specific to ferrous metals such as steel. Rust is formed when oxygen bonds with an atom of iron to form an iron oxide molecule. This molecule is considerably l... More » Science Chemistry

Building a model bridge to demonstrate aerodynamics and exposing metal to chemicals to identify how rust forms are two ideas for science projects. Other ideas are capturing rainwater to create a renewable energy source a... More » Education K-12

Rust on metal is caused by surface metal atoms and molecules forming metal oxides in the presence of oxygen and water. Iron is the most common material that rusts, forming iron oxides, but most other metals can rust as w... More » Science Chemistry Atoms & Molecules
