You would use a magnet to remove the iron filings from the sand. Iron is a ferrous (magnetic) metal and sand is non ferrous. (Other than Black Sand).
What Are The Physical Properties Of Sand And Small Iron Filings?
I did this today you put the sand and iron filling on newspaper put your magnet in a bag and put it over the iron filing and than take the magnet out of the bag and then all the iron filing will fall of leaving two groups ( sand and Iron filing ) :) p.s not sure about the properties 1 might be that is is magnetic :) cheers

Physical properties are those that you can observe by just looking at the substance..the physical properties of iron filling is its color, appearance, texture, odor, melting point, boiling point, density, solubility, polarity, and many others.
