Filtration
Distillation
Chromatography
Evaporation
Which sequence of separation techniques would you use to separate a mixture of water, tiny iron nails, gravel and glass marbles?
Use a magnet to remove the iron nails, then use sieving to separate the gravel and glass marbles, and finally use filtration to separate any remaining solids from the water.
Use filtration to remove the water first, then use a magnet to separate the iron nails, and finally use evaporation to separate the gravel and glass marbles.

A teacher made a sugar water mixture in a glass container using tap water and sugar. What should the teacher do to separate the sugar from the water after the sugar is dissolved into the water?
The teacher should freeze the mixture to separate the sugar and water.
The teacher should boil the mixture until the water evaporates and leaves the sugar in the glass.
The teacher should pour the mixture through a filter to trap the sugar as the water passes through.
The teacher should use a magnet to attract the sugar to the bottom of the glass.
Sugar and sand were added to water, then stirred. The mixture was then poured through the filter paper. Which statement correctly tells what happened?
the sugar and the sand both stayed on the filter paper and the water went through the filter into the beaker
the sand stayed on the filter paper and the sugar and water went through the filter into the beaker
the water, sand, and sugar all went through the filter paper and into the beaker
the water, sand, and sugar all stayed on the filter paper, and nothing went into the beaker
Which of the following, if added to water, would change its shape?
glass
salt
sand
wood
If I pour sand and water onto a filter, what will happen?
water and sand will go through the filter
sand will get caught in the filter, water will pass through
both sand and water will get caught in the filter
In filtration, what is the part that remains called?
What physical property changes when you add lemon juice to water?
The color of the lemon juice changes.
The color of the water changes.
The lemon juice sinks to the bottom.
