Separating Mixtures

Choose sieves, magnets, filters, and evaporation.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 46

Mixtures can be taken apart, because each material keeps its own properties. Pick a tool that uses a difference.
A sieve lets small pieces fall through its holes. A magnet pulls out iron and steel.
A filter traps solid bits and lets liquid through, so it can catch sand in water.
Dissolved salt passes right through a filter. To get it back, let the water evaporate. The salt stays behind.
