NCERT Class 6 Science Chapter 9
Methods of Separation in Everyday Life
This chapter introduces Class 6 CBSE students to various techniques used to separate mixtures in daily life and industry, including sieving, filtration, evaporation, distillation, and magnetic separation. Students understand why separation is necessary and how the appropriate method depends on the properties of the substances in the mixture. Real-life applications make these concepts relatable and practical.

Key Terms
- Filtration
- A separation technique that removes insoluble solid particles from a liquid using a filter (like filter paper).
- Evaporation
- A method of separating a dissolved solid from a liquid by heating the solution until the liquid vaporizes, leaving the solid behind.
- Sieving
- A method of separating solid particles of different sizes using a sieve or mesh that allows smaller particles to pass through.
- Magnetic Separation
- A method of separating magnetic materials (like iron filings) from non-magnetic materials using a magnet.
- Distillation
- A separation technique that separates liquids based on their different boiling points by heating and then condensing the vapour.
- Decantation
- A method of separating a mixture by carefully pouring off the liquid while leaving the sediment at the bottom of the container.
Frequently Asked Questions
What are the methods of separation of mixtures in Class 6 Science?▾
Class 6 covers several methods of separation including filtration (for insoluble solids in liquid), evaporation (for dissolved solids), sieving (for mixed solids of different sizes), magnetic separation (for magnetic materials), and distillation (for liquids).
What is filtration in Class 6 Science Chapter 9?▾
Filtration is the process of passing a mixture through a filter medium (like filter paper) to separate insoluble solid particles from a liquid. The liquid that passes through is called the filtrate, and the solid left behind is the residue.
How is salt separated from water in Class 6 Science?▾
Salt is separated from water using evaporation. When the saltwater solution is heated, water evaporates as vapour, leaving behind the solid salt. This is also how salt is obtained from seawater in natural salt pans.
What is magnetic separation used for in Class 6?▾
Magnetic separation is used to separate magnetic materials from non-magnetic ones. For example, iron filings can be separated from a mixture of sand and iron filings using a magnet. It is also used industrially to remove iron from food grains.
What is the difference between filtration and sieving in Class 6 Science?▾
Sieving separates particles of different sizes from a mixture of solids (like separating stones from flour), while filtration separates insoluble solids from liquids (like separating sand from water) using a filter medium.
