Iron filings, 12 ounce jarSprinkle these iron filings on a piece of paper and then move magnets underneath to create magnetic field patterns. For less mess, sprinkle iron filings into a clear plastic page protector or into a plastic petri dish. You'll get 12 ounces of fine mesh iron filings in an easy-to-dispense jar that's just right for a classroom or large group. Ages 8 & up with adult supervision.Overall Rating: ![]() Write an online review and share your thoughts with other customers Sort Reviews: Newest | Oldest | Highest Rating | Lowest Rating - Monday, March 15, 2010homeschoolmom Reviewed By: Rhonda Wiggins I did not know how much of this we would need for the science experiment so I got the 12 ounce jar. This was way more than I needed, but I will save the rest for later experiments. |
