If you spilled a container of iron filings on the ground, how would you separate the iron fillings from the soil using their individual physical properties?

Use a magnet to remove the iron filings from the soil.
MAGNETISM
To separate the iron filings from the soil, you can take advantage of their different physical properties. Here's a procedure you can follow:
1. Use a magnet: Iron is a magnetic material, so a magnet can be used to attract the iron filings. Place a strong magnet near the mixture and move it around gently. The iron filings will cling to the magnet, allowing you to separate them from the soil. You can repeat this process multiple times to ensure you've removed all the iron filings.
2. Sieving: If there are larger soil particles mixed with the iron filings, you can also use a sieve. A sieve is a mesh-like tool that allows smaller particles to pass through while capturing larger ones. Place the mixture on the sieve and gently shake it or tap it. The soil particles will fall through the sieve, while the iron filings remain on top. Carefully collect the separated iron filings.
3. Using water: If the soil and iron filings are not easily separable using a magnet or sieve, you can try using water. Iron filings are heavier than most soils; therefore, they will sink if the mixture is stirred with water. Fill a container with water and add the mixture to it. Stir the mixture vigorously to allow the heavier iron filings to sink to the bottom. Then carefully decant the water, leaving the iron filings behind. You may need to repeat this process a couple of times to ensure efficient separation.
Remember to exercise caution while performing these steps. It's important to handle magnets safely, and if you're dealing with potentially contaminated soil, make sure to take necessary precautions and dispose of it properly.
