Separating a mixture

Start with sand, salt and water.

1. STIR

The salt dissolves. The sand does not.

2. FILTER

Sand stays on the filter paper.

Salt solution passes through.

3. CHOOSE WHAT TO COLLECT

SALT: evaporate some water and allow crystals to form.

WATER: boil, then cool the vapour to collect liquid water.

Follow your teacher’s heating and safety instructions.
