Iron Bar Lab

This lab activity uses cereals that are fortified with iron, hot water, a drinking glass, and white magnet stirring bar. The students weighed the dry cereal before placing it in the glass. The students place the magnet stirring bar at the bottom of the glass then they place the cereal and hot water in the glass. The students then stir the items for a set time, after which they remove the magnet stirring bar. There should be dark slivers of iron left on the bar. The students then removed the slivers of iron from the bar and let them dry overnight.
The purpose of this activity was to have students participate in an engaging hands-on activity that simulated the extraction process of minerals and elements that occur in the real environment.
