Rusting Steel Wool Experiment
This experiment with Steel Wool is easily done at home with supplies that you likely have on hand or that are easily accessible. The Steel Wool experiment explores the chemical reaction of rust that occurs when water, air and other substances come in contact with metals that contain iron. This experiment will take 24 hours to observe and will give a hands on look at why children should remember to stow their toys and bicycles away and keep them out of the elements.
How to Do It
The chemical reaction of rust is a common reaction that happens to iron and metals that contain iron. Rust is caused by the metal's exposure to air and water and is accelerated by the presence of salt. The steel wool in jars 1 and 3 will rust and deteriorate more slowly than the other jars. Containers 2 and 5 will only start to show rusting if there is some air trapped underneath the lid of the jar.
