Abstract
Cereal manufacturers have a few choices for how they include iron in their products. Some cereal manufacturers prefer to add particles of pure iron metal (called elemental iron or reduced iron) because elemental iron is stable in storage and does not affect the cereal's flavor. General Mills' brand-name "Total" is one such cereal. The addition of this strongly magnetic form of iron allows "Total" cereal to be used in the two demonstrations described in this article. In the first, a flake of "Total" cereal is inserted between the two poles of a permanent magnet. The iron in the cereal allows the flake to remain suspended between the two poles. The second uses crushed "Total" cereal and a neodymium magnet. The crushed cereal is scattered over clear Plexiglas and the magnet can be moved around underneath. This drags the iron filings through the crushed cereal.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.


C&EN CLICs

Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
