Watch on YouTubeVideoSieving
Separate particles of DIFFERENT SIZE using a mesh. Small particles fall through; large ones stay on top.
Uses:
- Bran from flour (in a kitchen sieve)
- Gravel from sand (construction)
- Tea leaves from tea (strainer)
The mesh size determines what passes through.
Example
Atta (flour) with tiny bran chunks → sieve → fine flour falls through, bran stays on top.
💡 Tip:Sieving = SIZE-based. Doesn't work if particles are similar in size.
