Watch on YouTubeVideoSedimentation, decantation, filtration
- Sedimentation: heavy insoluble particles settle down when a mixture is left undisturbed.
- Decantation: carefully pour off the clear upper liquid, leaving the sediment behind.
- Filtration: pass the mixture through a filter (paper, cloth, sand). Solid is trapped; liquid (filtrate) passes.
Muddy water example: Let it SETTLE (sedimentation) → pour off clear water (decantation) → any fine particles caught via filter paper (filtration).
Example
Preparing drinkable water from a muddy river: sedimentation + decantation + filtration + boiling = safe to drink.
💡 Tip:Sedimentation + decantation is free and simple. Filtration is more thorough.
