Suppose you have a mixture of iron filings, sand, and sugar and you want to separate the three. Fill in the materials you expect to see at each step as you perform the actions shown to separate them. The materials you may expect to see are: iron filings, sand, sugar, and sugar water.

Explanation:

mixture of iron filings, sand, and sugar

First Step - Iron Fillings

Use a magnet to separate the iron fillings from the mixture. Due to magnetic properties of the iron fillings, the magnets would attract the iron fillings and separate it from the mixture.

Second step - Sand

Place the sand and sugar mixture in water. The sugar would dissolve in water and the sand easily separated by filtration.

Third step - Sugar and Sugar water

Boil the sugar water to remove the water and place in the refrigerator for crystallization of the sugar.
