Materials:
* Iron filings
* Small pieces of lead
* A strong magnet
* A clear container (like a glass or plastic bowl)
* A spoon or spatula
Procedure:
1. Mix the metals: Carefully combine the iron filings and lead pieces in the clear container.
2. Apply the magnet: Hold the magnet above the mixture. You'll see the iron filings clinging to the magnet.
3. Lift and separate: Slowly lift the magnet, and the iron filings will come with it, leaving the lead behind in the container.
4. Repeat if needed: If some iron filings remain, repeat steps 2 and 3 until all the iron is separated.
Why this works:
* Magnetic properties: Iron is a ferromagnetic material, which means it's strongly attracted to magnets. Lead, on the other hand, is not magnetic.
* Separation by magnetism: The magnet pulls the iron filings away from the lead, allowing for a clean separation.
Safety Precautions:
* Always handle magnets with care. They can be strong and can pinch fingers if not handled properly.
Let me know if you'd like to try another separation experiment!
