This demo shows how flakes of iron can be extracted from iron-fortified cereals with the use of a strong magnet. The demo shows a physical separation process and provides students with a good example of how one component (the iron) can be separated from a heterogenous mixture (the cereal). The demonstration can lead to discussions about the need of, and uses for, iron in biological systems.
