Rusting is a chemical reaction where Iron turns redish-brown.

Iron needs water and air to rust.

We paint Iron to stop it from rusting.


These gears were shiny but the Iron has rusted.	This pipe was painted to stop it rusting but where the paint has been damaged the Iron has started to rust.

Place 5 Iron nails in different conditions in sealed containers.

1 nail in a test tube with a small amount of water and air.

1 nail in a test tube with a small amount of salty water and air.

1 nail in a test tube with air and some dry rice to keep the air dry.

1 nail in a test tube full of water to keep the nail submerged.

1 nail wrapped in plasticine to stop any water or air getting to it. (Dipped in wax will also work).
