Materials:
* Iron filings and sulfur powder mixture
* A strong magnet (a bar magnet or horseshoe magnet works well)
* A shallow, non-metallic container (like a plastic tray or bowl)
* A clean sheet of paper
Procedure:
1. Spread the Mixture: Pour the iron filings and sulfur powder mixture into the shallow container, spreading it out evenly.
2. Apply the Magnet: Carefully hold the magnet above the mixture, not touching the container. Move the magnet slowly back and forth across the surface.
3. Observe the Iron: You'll notice the iron filings being attracted to the magnet and forming a clump or a line along the path of the magnet.
4. Collect the Iron: Slide a sheet of paper under the magnet to collect the iron filings.
5. Repeat: Move the magnet over the remaining mixture several times, collecting the iron filings each time.
6. Clean Up: Once most of the iron filings are removed, you'll be left with the sulfur powder. Discard the iron filings and clean up your workspace.
Why This Works:
* Magnetism: Iron is a ferromagnetic material, meaning it's strongly attracted to magnets.
* Non-magnetic Sulfur: Sulfur, on the other hand, is not magnetic and will not be affected by the magnet.
This method allows you to easily separate the two substances based on their magnetic properties.
