The property that could allow a student to easily separate sand and iron filings is magnetism.
The property that could allow a student to easily separate sand and iron filings is magnetism. Here's why:
1. Get a strong magnet: To separate sand and iron filings, you will need a magnet with a strong magnetic force. The stronger the magnet, the more effective it will be in separating the iron filings from the sand.
2. Use the magnet to attract the iron filings: Place the magnet in a plastic bag or wrap it with a tissue or paper towel. Then, move the magnet over the mixture of sand and iron filings. The magnet will attract the iron filings due to its magnetic force.
3. Separate the iron filings from the sand: As you move the magnet over the mixture, the iron filings will be attracted to the magnet and stick to it. Continue moving the magnet around until you have collected all the iron filings.
4. Discard the sand: Once you have separated the iron filings using the magnet, you can simply pour off the remaining sand. Since sand is not magnetic, it will not be attracted to the magnet and will remain in the container while the iron filings are removed.
By using the property of magnetism, a student can easily separate sand and iron filings in a mixture.
