Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals. Humans need vitamins and minerals--including some metals--in their diets, and this experiment helps learners understand the chemistry of the food they eat. This activity (located on page 2 of the PDF) is one of three activities in the Take Home guide for the Everyday Chemistry unit in OMSI's Chemistry Lab. Also included in the PDF are two additional activities: Spicy Indicator and Mystery Writing.
