Worked practice questions

Which method separates pebbles from sand most quickly?

  1. Distilling
  2. Sieving
  3. Filtering
  4. Dissolving
Show answer and solution

Correct answer: B. Sieving

1. Pebbles and sand grains are both solid but they differ greatly in size. 2. A sieve has openings that let the small grains fall through. 3. The larger pebbles cannot pass and stay behind on the mesh. 4. Sieving is therefore the right method when the parts differ in size. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), Sieving_

Muddy water is poured through filter paper. What is the clear liquid that passes through called?

  1. The residue
  2. The solvent
  3. The mixture
  4. The filtrate
Show answer and solution

Correct answer: D. The filtrate

1. Filtration separates a solid from a liquid using a fine paper. 2. The liquid that comes through the paper is called the filtrate. 3. The solid caught on the paper is called the residue. 4. So the clear liquid collected below is the filtrate. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), Filtration_

Iron filings are mixed into dry sand. Which method separates them best?

  1. Using a magnet
  2. Using a filter
  3. Using a sieve
  4. Using heat only
Show answer and solution

Correct answer: A. Using a magnet

1. Iron is magnetic while sand is not. 2. A magnet held above the mixture picks up the iron filings only. 3. The sand is left behind, so the two are separated. 4. A sieve would fail here because both parts are made of similar sized grains. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), Magnetic separation_
