The investigation that could demonstrate a chemical property of iron is:
**Performing an investigation to show how iron reacts with oxygen to form rust.**
This investigation shows a chemical change, as rusting involves a chemical reaction between iron and oxygen, resulting in the formation of iron oxide (rust), which has different chemical properties than elemental iron.
