Student Feedback: In Collegedunia NCERT revision checks, students found Chapter 9 easier when every method was linked to the property that makes it work.
- 76% needed a clear difference between filtration, decantation and evaporation.
- 69% wanted examples from kitchen, farming and recycling.
- 63% revised faster with a method-choice flow chart.
Class 6 Science Chapter 9 Notes Overview
Chapter 9 shows why substances are separated in everyday life. We may remove an unwanted component, separate two useful components, or recover a dissolved solid from a liquid. The key is to identify a difference in property.
| Method | Property used | Daily example |
|---|---|---|
| Handpicking | Size, colour or shape | Stones from pulses |
| Winnowing | Weight difference | Husk from grains |
| Sieving | Particle size | Bran from flour |
| Evaporation | Water changes to vapour | Salt from salt solution |
| Filtration | Insoluble solid cannot pass through fine pores | Tea leaves from tea |
Solid Solid Separation Methods in Chapter 9
Solid solid mixtures are separated by handpicking, threshing, winnowing, sieving or magnetic separation. The chosen method depends on what difference is easiest to use.
- Handpicking works for a few visible particles.
- Threshing separates grains from stalks.
- Winnowing separates lighter husk from heavier grains.
- Sieving separates solids of different sizes.
- Magnetic separation removes iron from non-magnetic materials.
Solid Liquid Separation Methods in Chapter 9
Sedimentation, decantation, filtration and evaporation are used when a solid is mixed with a liquid. Muddy water, tea leaves in tea and salt solution are the main NCERT examples.
| Situation | Method | Reason |
|---|---|---|
| Mud settles in water | Sedimentation and decantation | Heavy insoluble particles settle |
| Tea leaves in tea | Filtration | Leaves cannot pass through strainer holes |
| Salt dissolved in water | Evaporation | Water evaporates and salt remains |

Choosing the Correct Separation Method
Always start with the mixture. Then ask which property differs most clearly. This prevents confusion between similar methods like decantation, filtration and evaporation.
- If particles are visible and few, use handpicking.
- If solid particles differ in size, use sieving.
- If one solid is light and another is heavy, use winnowing.
- If an insoluble solid is in a liquid, use sedimentation, decantation or filtration.
- If a solid is dissolved in a liquid, use evaporation to recover the solid.
- If one part is iron, use magnetic separation.
