Key Stage 2

Meaning

An insoluble material is one that cannot be dissolved in water.

About Insoluble Materials

Insoluble is the opposite of soluble.
When an insoluble material is put in water it can still be seen, no matter how much you stir the water.
An insoluble material will make water appear cloudy.

Examples

Sand is insoluble because it does not dissolve in water.

Key Stage 3

Meaning

An insoluble material is one that cannot be easily dissolved in a solvent.

About Insoluble Materials

Insoluble is the opposite of soluble.
When an insoluble material is put in a solvent (usually water) it can still be seen, no matter how much you stir the solvent.
An insoluble material will make the solvent appear cloudy.
Many materials are soluble in some solvents and insoluble in other solvents.
Many materials we call insoluble can dissolve in a solvent a small amount but so little that the rest sinks to the bottom of the solvent to form a sediment.

Examples

Sand is referred to insoluble in water because very little can dissolve in the water.
