Materials List: Design a Process to Remove Iron:
Cereal Magnets

Each group needs:

  • 480 ml (1 cup) cereal with a high iron content, such as TotalĀ® or any cereal that contains 100% of the recommended daily allowance of iron

To share with the entire class:

  • magnets of varying strengths, such as magnets generally used in classrooms; refrigerator magnets have less strength and may not work, but provide students with an alternative with which to experiment
  • ZiplocĀ® bags
  • cups of water
  • blender
  • electronic balance that is sensitive enough to be able to detect small changes in weight (at least one tenth of a gram); if not available, see the Procedure section for alternative ways to quantify the amount of cereal removed
